How do we achieve sustainability?

No one would deny the importance of sustainability. But how do we achieve it?

According to Jin, the answer can be found in the ‘Life Cycle Approach’ model. This model provides a better idea of how sustainability can be achieved. Life Cycle Approach seeks to prevent the root causes that can threaten the environment by identifying and considering all stages of a product’s life cycle, beginning with the extraction of raw materials.

Take vehicle emission as an example, it is widely known that electric vehicles produce far less pollution than gasoline vehicles. However, a closer look at vehicle operation would reveal that electric vehicles also produce a fair amount of pollution by burning carbon when generating electricity.

Can Steel be life-cycled?

So how does steel fit into the Life Cycle Approach?

Jin showed little bit more on details of the reasons why steel should be considered as an important eco-friendly as product or a material. Beginning with the manufacturing stage, the by-products of steel production, such as slag, can be recycled to make raw materials for road construction. Once in use, its longevity is a great advantage in terms of sustainability efforts. Steel used in buildings and various infrastructures boast a life span of almost 100 years. Steel used in vehicles and various machines also can last over 10 years.

After it has served its purpose, steel is still highly recyclable and boasts a recycling rate of nearly 90%. Because it can be infinitely recycled while maintaining its inherent property and quality intact, steel is considered the most suitable material for circulation economy.

POSCO’s Clean advanced technology may be the solution for green society

Steel is essential for our sustainable future

Jin mentioned that the POSRI reports clearly illustrates that various ways of steel can be applied to the Life Cycle Approach and its viability as an integral element for sustainability. POSCO strives to stay ahead of the curve by utilizing its cutting-edge technology to develop innovative products and solutions, such as the GIGA STEEL and FINEX® smelting processes.

Finally, Jin assured that with the Life Cycle Approach in mind, POSCO takes pride in all the efforts in reducing greenhouse emissions and in paving the way towards a sustainable society.

This year, more skyscrapers will fill the skylines of cities, mostly in Asia. Continuing on from previous years, cities, architects and the general public alike are favoring low-energy, sustainable buildings and showing a tendency to renovate existing buildings with reinforcements where possible.

Take a look at 2 of the tallest skyscrapers built in 2017, and some of the most exciting building projects coming scheduled for completion in 2018.

2017: Ping An Finance Center

The Ping An Finance Center is located in the city of Shenzhen, and is the second tallest building in China and fourth tallest building in the world. The entire structure measures 599.1 meters, or 1,965 feet, offering 119 floors of office and retail space.

The Ping An Finance Center is classified as a composite building, meaning both steel and concrete materials are used to make up the main structural parts of the skyscraper. This can apply to any of the following combinations – steel columns with concrete beam floors, steel structure with a concrete core, steel columns encased in concrete or a system of steel tubes filled with concrete. The exterior is outfitted with a sculpted stainless steel facade for maximum corrosion resistance to coastal climate.

2017: Lotte World Tower

Korea’s Lotte World Tower is the tallest building in Korea and the fifth tallest building in the world measuring 555.7 meters and 1,823 feet from the ground to the very top. Construction began in Seoul back in 2011 and took 7 years to complete. The 129-story building is made of a reinforced concrete core, concrete encased steel columns and steel floor spanning.

POSCO supplied the 40,000 tons of steel to build the Lotte World Tower, consisting of both regular and thermomechanical control processed (TMCP) steel. As part of POSCO’s solutions marketing, the company proposed using 120 mm thick high-performance grade steel (SM490TMC) instead of welding 40 mm and 80 mm thick plates together for better performance and cost efficiency. The steelmaker also proposed the use of a steel column flat plate structure and steel piping for enhanced shock, high-wind and fire resistance.

Lotte World Tower also features solar panels, wind turbines and water harvesting systems as part of a sustainable, eco-friendly design.

2018: Hanking Center Tower

The Hanking Center Tower scheduled for completion in March of 2018, will set a new world record as the tallest all-steel building in all of Asia. Most skyscrapers are made of a mixture of concrete and steel, but the Hanking Center Tower is composed of a unique, all-steel structural system. The main body is also detached from the core by about 9 meters, held together by a series of sky bridges and steel braces to allow the building flexibility to withstand seismic activity and maximum exposure to natural light.

At 350 meters, or 1,148 feet, the Hanking Center Tower will be classified as a super tall building when completed in west Shenzhen, China. The building underwent extensive seismic and wind tunnel tests for performance verification, and residents and visitors alike will be able to enjoy the sky gardens and spacious open spaces in the heart of the city.

2018: Salesforce Tower

San Francisco has a new tallest building with the opening of the Salesforce Tower in January of this year. Standing at 326.1 meters, or 1,070 feet, the skyscraper also made extensive use of steel for its columns and floor spanning and features a reinforced concrete core. The Salesforce Tower is also one of San Francisco’s most-expensive buildings at USD 1.1 billion.

Not only is the 65-story building San Francisco’s tallest building, it is the city’s first commercial building to use a water recycling system. The city government, Boston Properties and Salesforce teamed up to support blackwater reuse that will give tenants of the building access to recycled water. The skyscraper also has net-zero greenhouse gas emissions.

2018: Comcast Technology Center

The 341.7 meters, or 1,121 feet tall Comcast Technology Center opened early this year, and stands as Philadelphia’s tallest skyscraper. The USD 1.6 billion building also has smart features, including a central plant that acts as the brain of the building, using artificial intelligence to learn human patterns.

The skyscraper can track the number of people inside, predict weather patterns and will only generate just enough energy required for any given time. The building also makes use of water running through all parts of the building to cool temperatures and has a special, silver coated glass which can repel heat from the sun. As such, the Comcast Technology Center is one of the most technologically advanced and green buildings in the U.S.

Continuing on from a strong year of construction in 2017, the new skyscrapers of 2018 and beyond will continue to strive for environmental sustainability, incorporate newer technologies and make extensive use of steel for cost efficiency and safety.

As structural damage is the leading cause of injury and deaths during an earthquake, architects, engineers and builders need to make sure buildings are built with the right materials and design.

The Materials

The most dangerous type of earthquakes are ones that trigger horizontal movements, because tall buildings are better at resisting vertical loads than horizontal ones. These ground motions can damage building foundations in a matter of minutes, causing severe injuries and deaths. Building a structure to withstand seismic waves starts with the right materials with the right properties, and steel is by far the most widely used material for building earthquake-resistant buildings.

According to the World Steel Association, ductile buildings are safer as they dissipate energy from seismic waves. A building will typically have ductile parts that can undergo plastic deformations without complete structural failure during an earthquake. Steel is the most common type of material for such parts.

Moreover, due to the law of inertia, the lighter the building, the less force seismic waves will exert on the building. That’s why it’s important, especially for taller buildings, to be made of light and flexible materials such as steel that can “bend” with the movement of earthquakes. On average, multi-story steel buildings are 60 to 70 percent lighter and 10 times stronger than concrete-framed buildings of the same size.

The Design

With steel, builders can add vital designs and reinforcements to keep the structure standing through an earthquake. Here’s some of the most widely-used measures.

Cross braces transfer the force of an earthquake to the ground. (Source: Earthquakes in India)

The structural integrity of buildings can be reinforced with steel cross braces that frame the exterior of a building in an x-shape. Ultimately cross braces can transfer the force of seismic waves back down to the ground, instead of letting the building take the hit. Builders can also reinforce the walls of buildings with additional vertical walls, or shear walls, that add stiffness to the frame of the building, allowing it to resist swaying or horizontal movements.

Base isolation involves separating the building from the foundation so that the isolators to absorb shock from the earthquake. The isolators allow the building to move at a slower pace because they dissolve a large part of the shock. Moment-resisting frames also effectively dissipate energy from floors and roofs to the building’s foundation and the stiff yet flexible frames can change shape during an earthquake. Although more costly, moment-resisting frames enable buildings to withstand an earthquake with excessive horizontal movement.

Putting it into practice with POSCO’s Steel House

In September 2017, Young Bae Kim’s home in Gyeongju province, Korea was hit with a 5.8 magnitude earthquake, just 8.9 km from where the earthquake started. Surprisingly, Kim’s home was unscathed. “I could feel the ground shake, but the house was completely under control.” Kim expressed.

Kim lives in one of the Steel Houses built by POSCO employees who volunteer to build homes and bridges for communities in need. Each Steel House is made with POSCO’s lightweight structural steel known for its durability, fire resistance and vibration resistance. The homes also incorporate PosMAC, a specialized galvanized steel that is 5 to 10 times more corrosion-resistant than standard steel and is more durable and affordable.

POSCO Employees volunteer their time to build steel houses in rural communities.

Because all the Steel Houses survived the Gyeongju earthquake while other homes were damaged, more and more people in Korea are choosing steel for their homes over traditional building materials such as wood and concrete. The same trend can be observed in Japan, where earthquakes are much more frequent. In order to build more earthquake-resistant buildings, steel is still the best solution available.

However, these building projects are on another level of huge, and with all the megacities popping up throughout the country, China boasts many of the biggest infrastructure projects in the world. Here’s the Steel Wire’s look at some of the most impressive to date.

Three Gorges Dam

China is home to the largest dam in the world, measuring 1.5 miles in length and sitting 60 (!) stories tall. The Three Gorges Dam took 1.92 million tons of rolled steel to complete, along with 10.82 million tons of cement and 1.6 million cubic meters of timber. The dam opened in 2003 on the Yangtze River and last year, generated a record-high 97.8 billion kilowatt-hours of electricity, 4.35 percent higher than the previous year.

Beijing Capital International Airport

Beijing Capital International Airport (PEK) was the second largest and busiest airport in the world in 2016, just behind the Hartsfield–Jackson Atlanta International Airport in the U.S. PEK recorded 94,393,454 passengers that flew in and out in 2016, a 5 percent increase from 2015, and is easily the biggest airport in all of Asia.

The first phase of the airport cost USD 3.5 billion and was completed in 2008, but in order to handle the growing number of passengers, an expansion project is planned for 2025. The estimated 5-year project will almost double PEK’s capacity and cost an additional USD 13 billion.   

Jiaozhou Bay Bridge

China is also home to the longest sea-crossing bridge in the world. The massive structure stretches over 26.4 miles and connects the cities of Qingdao and Huangdao. The 110ft width accommodates 6 traffic lanes that are supported by 5200 steel pillars.

The bridge first opened in 2011 and took USD 2.3 billion and over 10,000 workers to build. The Jiaozhou Bay Bridge also took 450,000 tons of steel to complete, allowing the bridge to be able to withstand earthquakes up to 8.0 in magnitude, typhoons and the force from a 300,000-ton object.  

Jiuquan Wind Power Base

Not surprisingly, the largest wind farm in the world located in China. Jiuquan Wind Power Base is made up of 7,000 turbines that generate enough electricity to sustain a small country. The plant was approved in 2008, and the government has pledged an additional USD 17.4 billion by 2020 as part of the effort to develop China’s renewable energy industry. For now, only 3.3 percent of all the electricity generated in China comes from wind turbines. With the additional investment, Jiuquan Wind Power Base will be able to generate a massive 20 gigawatts of sustainable electricity.

New Century Global Center

What does the biggest building in the world look like? A mini country. Located in Chengdu, Sichuan province, the New Century Global Center combines a shopping mall, water park, hotels, movie theaters, offices, restaurants, ice rink and more into 19 million sq.ft. of space. The structure is made of glass and steel and measures 500 meters long, 400 meters wide and 100 meters high. Designed by architect Zaha Hadid, it even has artificial sun for the perfect weather, 24 hours a day.

Port of Shanghai

The world’s biggest ports are mostly located in China, and the biggest one is the Port of Shanghai. In 2012, 744 million tonnes of cargo and 32.5 million twenty-foot equivalent units (TEUs) of steel containers passed through the port. The entire area of the port on the Yangtze River covers 3,619km² comprised of 3 main ports: Wusongkou, Waigaoqiao and Yangshan Deep-Water Port. About 25 percent of China’s trade passes through the Port of Shanghai, or 2,000 steel container ships per month.

Most recently, the 4th phase of the Yangshan Deep-Water Port was completed, making it the largest automated port in the world. It spans across 2.23 million square meters, and can automatically handle 4 million standard containers per year, or 25 per hour. It was also built to accommodate the heaviest ships in the world.

China is using its steel to build up the country’s infrastructure, and set world records along the way. Besides being impressive in size, the structures are expected to contribute to greater connectivity and economic prosperity throughout China.

The U.S. is the birthplace of many iconic figures, movies, and buildings. The Statue of Liberty is one such work of art which stands as a symbol of freedom and independence. The Empire State building is another architectural icon in the center of New York, a city which in and of itself represents the U.S. Although these monuments appear majestic on the exterior, it is their interior composition that has kept them standing tall all these years. These and other international iconic structures embody the limitless ways steel builds culture around the globe.

The Statue of Liberty

A Gift from the French

An early sketch of the Statue of Liberty (Image courtesy of Copper Development Association Inc.)

More than a hundred years ago, the French sent a giant gift to celebrate America’s independence and to honor their friendship. The Statue of Liberty was first assembled in France, taken apart, shipped to the U.S. and then erected once more. It still stands tall, but even stronger today thanks to some important improvements made along the way.

As the Leaning Tower of Pisa is to Italy and the Eiffel Tower is to France, the Statue of Liberty embodies and represents America’s values of freedom and independence. Although Lady Liberty looks as smooth and stunning as her first debut, her journey was nothing short of rocky.

The statue was assembled in the U.S. in 1886. The iron and copper figure stood the test of time for almost 100 years. However, from 1982 to 1986, the statue underwent major reparations to so that Lady Liberty could make it to her centennial anniversary in 1986. It was a costly effort, and interestingly, marked one of the earliest joint efforts between the private and public sectors to fund a public project.  

What was wrong with Lady Liberty?

In short, the Statue of Liberty can be broken down into three main parts: the copper exterior (a sheet of copper that covers the entire statue), the internal skeleton or pylon made of puddled iron, and the Armature (a frame that connects the copper exterior to the internal skeleton).

The armature is made up of iron bars, 1300 of them, weighing 20 pounds each. Due to concerns about corrosion, layers of protective materials were applied to the bars, such as coal tar, aluminum, and lead. The coating itself weathered over the years and began to trap moisture. Thus, the iron started to rust.

Engineers decided to replace the entire armature, but with what?

Four prospective materials underwent extensive testing:

1. Aluminum bronze
2. Cupro-nickel
3. Ferralium
4. Stainless steel

The obvious choice was stainless steel as it would not rust, but also gift builders with its elasticity, light-weight, strength, and ductility.

Ten years after the repairs, in 1996, inspectors deemed the armature corrosion-resistant and it has remained so ever since. It would have been wiser and less costly to start with steel in the first place, as the engineers of the Empire State Building did, but it seems even steel could use… even more steel.

A Steel on Steel Testament

The Empire State Building Stands tall in the middle of New York City

In the Big Apple, The 86-year-old Empire State Building also recently underwent enhancements. Engineers added 39 tons of steel plates onto the building’s existing steel mast (the pointy part at the top, also known as the tower) to improve its carrying capacity.  

The planning for this project alone took over two years. Steelworkers, engineers, and builders had to take into account the bustling city below. High winds were another factor to consider. In the end, engineers came up with a cocoon-like encasing to be placed around the tower at the top of the building during construction to keep falling pieces in and strong winds out.  

Once set inside the cocoon, workers began wielding 39 tons worth of steel bars and plates onto the tower. The process was tedious as steel parts could only be transported into the cocoon in small pieces.  

In the end, the sturdier mast with a greater carrying capacity was worth the struggle.

The Empire State Building was built in 1931 and was the tallest building in the world at the time. Due to its unique design, the American Society of Civil Engineers named it one of the Seven Wonders of the Modern World. It is also a significant part of American culture, as the Empire State Building has been featured in more than 90 movies, including “King Kong” in 1933.  

Every year, the Empire State Building generates more than $100 million in revenue. About 20% of the revenue comes from the antennas attached to the 200-ft-tall steel broadcast tower. The remaining 80% is generated by the flocks of tourists that visit from all over the world, confirming the Empire State Building as an international landmark.  

However, it is not the only building receiving international attention and recognition.

The Leaning Tower of Abu Dhabi

Abu Dhabi is another country where steel lays the foundation for iconic buildings. The Capital Gate Building may not have a long history, but it is an architectural wonder. It is often compared to Italy’s Leaning Tower of Pisa, but it has four times leaner The Capital Gate leans to the west a whopping 18 degrees.

How is this possible?

Engineers used a technique called pre-cambered core. Basically, they offset the core to counter the gravitational force created by the leaning mass of the building. The core or base of the building is a 7-foot mass of steel mesh and concrete locked down to almost 500 piles, which are drilled 100 feet into the ground. The external skeleton called a diagrid is also made of steel. These features, as well as some extensive math equations, allow the building to stand tall, at an angle.

The landmark leans in the center of the Abu Dhabi National Exhibition Centre complex and the Capital Centre master development. It captured international attention when The Guinness Book of World Records confirmed the Capital Gate Building as the “World’s furthest leaning man-made tower” in 2010.  

The list of iconic steel structures is endless…

Although the ones we discussed are just three iconic structures, it’s easy to see why steel makes up so many other buildings, statues, and memorials all over the world.  In the U.S. alone, iconic structures such as the Brooklyn Bridge, the Gateway Arch in St. Louis and the Willis (Formerly Sears) Tower are all made of steel.

Steel is cheaper, more sustainable and more durable than other materials such as iron and wood.

In addition, emerging technology will only further enhance the compatibility of steel for architecture and construction. One promising area of innovation is 3D printing for buildings.

Printing Steel in 3D

The typical concrete construction process consists of:

1. Setting up a steel/metal frame (rods) for the building
2. Pouring concrete over the rods
3. Formwork- using a wooden “shell” to hold the concrete in place as it dries

The problem with this process is the formwork. Because custom-made formwork is extremely expensive and non-reusable, builders opt for standardized, block-shaped formwork. This limits design creativity on top of the economic and environmental inconvenience.

Mesh Mould is a digital 3D printer in the works by researchers at the ETH Zürich research institute. The printer would produce steel frameworks that are both fine and dense, so that poured concrete would not seep out before it solidifies. The developers of Mesh Mould also created a special concrete mix to accompany the steel frames. Mesh Mould would eliminate formwork completely. Not only will this make the whole construction process more sustainable, it will lower material expenses and also save time. Others have taken notice as well. Mesh Mould received the 2016 Swiss Technology Award.

Statues, building, and monuments can be made of numerous different materials. However, when exploring iconic buildings and monuments that have stood the test of time and breached scientific barriers, steel proves to be the perfect fit.

Upcycling ensures that resources are used to their fullest extent, minimizing the number of trips made to the landfill. Vivian Kim, a travel writer, takes us deeper into this topic and introduces two examples of upcycling architecture from her time in both Korea and the Netherlands.

Steel, an Ideal Material for Upcycling

Steel is 100% recyclable, which makes it one of the most ideal materials for upcycling. Other construction materials, such as wood and plastic, can only be recycled a limited number of times before they lose its original properties and functionality and need to be downcycled (recycled into a material that is of lower quality than the original material). Steel, on the other hand, never loses its original quality. In fact, it can even increase in value and be upgraded to a higher grade of steel with the same amount of energy it would take to recycle it.

Steel is also reusable. Entire buildings made of steel can be reused or have their lives extended by years, just by making small improvements. Because steel can be easily reused for its original purpose, there is less of a need to use raw materials from scratch, allowing for more sustainable construction.

Let’s take a look at some of the most widely recognized pieces of upcycling architecture in the Netherlands and Korea.   

Amsterdam’s Abandoned Shipyard Reborn as Cultural Hub

Utilizing recycled materials in the design of a building is nothing new. In fact, upcycling in the Netherlands had its beginnings in the 1960’s when a small, social movement began in Jordaan, a well-known neighborhood in Amsterdam. The Dutch began to mobilize the community to protect their historical buildings and prevent constant demolition from taking place. Local governments also recognized the importance of reusing and remanufacturing materials from an economic standpoint and began to push for more upcycling initiatives.

A great example of this is the NDSM ship wharf, the site of the former Dutch Shipbuilding and Dry Dock Company. Just a 15-minute ferry ride from Amsterdam Central Station, the NDSM was once one of the largest shipbuilding companies in the world. However, a shortage of shipbuilding orders led to the company’s eventual closure in 1984. The abandoned shipyard soon became the breeding grounds for “city nomads” and local artists to take their place and breathe new life into the empty buildings. Through their efforts, the NDSM quarter was transformed into what is now a cultural hotspot in Amsterdam.

The NDSM ferry stop in Amsterdam Central.

As soon as visitors step off the ferry, they are greeted by what looks like a scene from an eerie, sci-fi movie. The NDSM ship wharf is full of gray, bleak buildings covered with graffiti and steel containers that are painted bright red and blue.

The former NDSM wharf is now Amsterdam’s newest creative hot spot.

Crane Hotel Faralda in the Sky of Amsterdam

At the center of the NDSM wharf stands a monumental, 50-meter-high crane called Crane 13. It is painted in red, blue and yellow, the signature colors of Dutch artist Mondrian. Built in 1951 by Hensen Ltd., it was one of the largest cranes in the world but slowly faded from the public’s memory with the closure of the shipbuilding company.

The Crane Hotel Faralda, transformed from a rusty, old crane into a luxurious high-end hotel.

In the spirit of upcycling, the 60-year-old rusty crane was transformed into the Crane Hotel Faralda in 2013 despite immense technical challenges. The hotel, named after a female Dutch spy who saved hundreds of people during World War II, is made entirely of steel.

As a crane’s main purpose is to lift heavy objects, only the strongest of steel is used to build it. For this reason, High-Strength Low-Alloy Steel (HSLA) is often employed. It contains 0.05% of carbon and other raw materials such as chromium, nickel, molybdenum, and vanadium – the secret behind its enhanced strength. HSLA steel is also more resistant to atmospheric corrosion, enabling Crane 13 to withstand the strong Netherland winds of the North Sea for over 60 years.

In the following time-lapse video, watch how the rusty crane transforms into an iconic symbol of the NDSM quarter and one of Europe’s most unique and sensational hotels.

An old rice mill transforms into one of Seoul’s hotspots

Another example of upcycling that shifts the culture can be found in the quaint neighborhood of Seongsu-Dong, South Korea. Known as the “Brooklyn of Seoul”, Seongsu-Dong is known for its trendy and hip cafes embedded in between old warehouses and factories. Its roots can be traced back to the 1970s where steel, leather and printing factories once dominated the streets. But, beginning in 2010, a wave of cafés, galleries, and studios began to break into the bleak space, transforming the once gray industrial district to a colorful vibrant scene brimming with new sights and sounds.

Hidden within the streets of Seongsu-Dong is the Daelim Warehouse, an old rice mill that has in recent years, been upcycled into a multi-cultural hub that doubles as a café and performance/exhibition venue for the artist community. From the bare concrete walls to the metal rod ceiling structure, it retains the distinct flair of a warehouse, cultivating a special atmosphere that has people flocking to it on a regular basis. Because of its unique interior, it has even been acknowledged as one of the most Instagram-worthy spots in Seoul.  

[clickToTweet tweet=”Upcycling is more than just a passing fad – it will continue to be an integral part of a sustainable lifestyle.” quote=”Upcycling is more than just a passing fad – it will continue to be an integral part of a sustainable lifestyle.” theme=”style6″]

From the NDSM quarter in Amsterdam to the Seongsu-Dong neighborhood in Seoul, upcycling has become a worldwide trend improving our surroundings as we live, create and build. Just as steel has been with mankind for thousands of years, it will continue to play a crucial role in recycling, reusing and upcycling.

Advancements in products, production methods, and new technologies have helped POSCO expand the expectations of what a sustainable steel company should be.  

In honor of Earth Day, The Steel Wire takes a look back at seven recent initiatives & breakthroughs from the last year that have helped POSCO become an industry leader in sustainable development.

POSCO GIGA STEEL: Lighter for EVs, Less Production Emissions

As the auto industry heads toward producing lighter, more fuel efficient vehicles, they need materials that are both strong and light. Car bodies manufactured with POSCO GIGA STEEL and other advanced high strength steels could see a 26% reduction in total weight. Also, based on its life cycle assessment measuring carbon dioxide emissions from production to recycling, POSCO GIGA STEEL performs remarkably well as an eco-friendly material. According to the World Steel Association, steel emits 2.0 to 2.5 kg of carbon emissions when producing 1 kg of material while aluminum emits 11 to 12.6 kg when producing the same amount.

See how POSCO GIGA STEEL offers an ideal material solution for automakers looking to make more lightweight and fuel efficient cars.

POSCO’s Smart Factory Introduces Artificial Intelligence

When POSCO introduced artificial intelligence into its smart factory operations in February, they were able to create higher quality products using a more sustainable production method. Coating weight control is a highly sophisticated process that keeps the coating layer consistent. Quality can deviate depending on the worker, but with POSCO’s new AI technology they can ensure quality control while reducing wasted zinc during production.

Read more about how POSCO is using AI and smart factory technology to make its operations more efficient and sustainable.

POSCO’s Advancements in Lithium Extraction Recharge the Battery Industry

Lithium extraction traditionally takes anywhere from 12-18 months using a slow evaporation technique. However, POSCO’s new extraction method, which came online in February of this year, takes from 8 hours up to one month while also offering a purity rate of 99.9% and increasing the lithium recovery rate to over 80%, which reduces the resources needed for extraction making the process more sustainable and eco-friendly. Also, in a first for the industry, POSCO developed a way to extract lithium from recycled batteries. Both of these innovations have helped create more eco-friendly processes for an industry that is expected to grow exponentially in coming years.

POSCO’s World Premium Stainless Steel Shows No Corrosion After 18 Years at Incheon Airport

The first passenger terminal at Incheon International Airport was built in 2001 using POSCO’s 446M steel, and after 18 years, few signs of corrosion have been seen. Building exteriors and roofs are the most visible parts of buildings, while also being the most vulnerable to corrosion. Materials used in their construction should be both corrosion-resistant and aesthetically pleasing. Therefore, when planning for the second terminal, they decided to use the same type of steel along with the application of the bead blast process that will create a rough texture on the roof to lower the reflectivity rate for aircraft pilots during take-offs and landings.

Find out how POSCO’s stainless steel products offer decorative and durable interior and exterior options in buildings.

Daniel Libeskind says, “[I]n buildings that move us, there’s an element of care. It’s not a question of whether a building makes us feel good or bad. It’s about being moved. It’s something that goes very deep.”

Take a look at these three unique buildings that used steel in creative ways. Most architects and engineers work to hide the steel underneath the walls and floors, but these three architecture firms brought the steel to the exterior – and to dramatic effect. Even if you have never seen or been in these buildings, we can all imagine what it would be like. Try to focus on the emotions you may feel when you read about the buildings and tell us about it in the comments below.

Zaha Hadid’s Investcorp Building, Oxford University

The Investcorp Building, located in Oxford University’s St. Antony’s College, is part of the school’s Middle East Center. Named after the investment firm that donated £11 million to have it built, the building includes a library, classrooms, and offices. Designed by the late Zaha Hadid, considered to be one of the most famous avant-garde contemporary architects of our time, the project has evoked a multitude of emotions from those on campus.

Conspicuously different from the other Victorian buildings found on Oxford’s campus, the Investcorp Building has brought out supporters and detractors. Some said that it “Looks like a beached whale,” or “No, a crashed airplane.” While some of Hadid’s supporters, like the center’s director Eugene Rogan said, “Every line meant something. It bends the brain. I’m in love with this building and I can’t hide it… there’s something Daliesque about it.” The Independent even went so far as to say that it was “undoubtedly Hadid’s most intriguing small building.”

Many will argue that the building does not blend in well with its surroundings on Oxford’s campus, but it is also hard to deny the precision and expertise that went into the design. Love it or hate it, Hadid’s Investcorp Building is one that will fuel debate for decades to come.

Turkey’s Raif Dinçkök Yalova Cultural Center

The modern Raif Dinçkök Yalova Cultural Center was designed by Istanbul’s Emre Arolat Architects. It is a mini-city in a box with different multi-purpose facilities inside that are connected by a vast maze of ramps and walkways.

Its unique exterior is made of corten steel, short for “corrosion resistance” and “tensile strength,” a type of weathering steel that has no need for painting. Over time it develops a rust-like appearance while maintaining its resistance to atmospheric corrosion.

The intentionally rusted facade offers a blank canvas for the city and serves to heighten expectations of what might be inside.

Arch Daily says, “The surface, which is also suitable for recycling, acts as a natural palette, containing the changes it will go through, like the color and tone changes caused by oxidation. This movement will make the relationship between the city and the building more interactive.”

Frank Gehry’s Walt Disney Concert Hall, Los Angeles

Frank Gehry’s stainless steel Walt Disney Concert Hall remains one of the famous architect’s most well-known works – as well as one of the most famous buildings in LA. Architectural Digest called Gehry the “most important architect of our age,” and the LA Times said that “Disney Hall accomplishes all the things Gehry has become famous for and all the things he was supposed to be incapable of doing.” The stainless steel jutting out into the landscape is both striking but soft.

“Ten years after its debut, it remains the city’s greatest room.” -Christopher Hawthorne, LA Times

Some patrons have argued that entry into the hall is rather abrupt as one must move from the sidewalk directly into the lobby, with little fanfare. Then, having entered the hall, even the lobby is considered “narrow and asymmetrical.” But Gehry seemingly did this on purpose “in an effort to save the architectural and emotional payoff for the moment when you walk into the auditorium itself.” He realized that this building was to be a monument to the music and musicians that played there, and so he wanted the focus to be on that aspect – minimizing the rest for emotional effect.

Some of these landmarks date back more than 100 years, but they have endured. Go behind the scenes to see how director Damien Chazelle brought these classic buildings to life in the fantastical song and dance numbers of La La Land.

l Griffith Observatory

In La La Land, Griffith Observatory, and the park where it sits, is the setting for some of the more memorable scenes. Mia and Sebastian’s first dance number took place in Griffith Park on a road overlooking the city (see image below), and the observatory can be seen later in one of the couple’s various date sequences.

The Griffith Observatory opened in 1935 on land that was donated to the city of Los Angeles by Colonel Griffith J. Griffith in 1896. Sitting atop Mt. Hollywood, the observatory offers views of downtown LA, the Pacific Ocean, and the famous Hollywood sign. Visitors can access exhibitions on astronomy and space while also enjoying access to public telescopes and the Samuel Oschin Planetarium.

With construction starting in June 1933 in the midst of the Great Depression, designers found materials and labor were cheap. The concrete structure was supported by a steel structure, while the three domes were raised “by wrapping copper sheets around steel frames.” The observatory has stood the test of time, hosting millions of visitors since its opening in 1935. However, in 2002 the observatory temporarily closed for restorations. The $93 million renovation retained the art deco exterior while updating much of the interior, including the planetarium.

Due to its long history and iconic status in Los Angeles, the Griffith Observatory has appeared in many films and TV shows. In addition to La La Land, it can be seen in Rebel without a Cause (1955), The Terminator (1984), and even The Simpsons.

l Watts Towers

During one of the film’s montage sequences, Mia and Sebastian visit Watts Towers – a collection of 17 sculptures made of steel, metal, and concrete reaching heights of over 30 meters. Starting in 1921 and continuing for 33 years until 1954, Italian immigrant Simon Rodia made these sculptures using steel rebar, concrete, and wire mesh. He decorated them using found objects, mostly refuse, such as the green glass from cola bottles, seashells, and blue milk of magnesia bottles.

At age 75, Rodia decided to give up on the project and go live with his sister in northern California. The city of LA attempted to have the towers removed due to safety issues; however, the art community convinced them to conduct a stress test first. Steel cables were connected to each tower as a crane attempted to move them from their foundations. The steel and concrete structures held firm with the crane ultimately buckling under pressure – forcing the city of LA to acknowledge their safety and keeping them in place for the public to enjoy.

l Colorado Street Bridge

Sebastian and Mia also visited the famous Colorado Street Bridge, allowing audiences to revisit one of the older landmarks of Los Angeles. Finished in 1913, the Colorado Street Bridge was thought to be the highest concrete bridge at that time. Its beautiful arches sit 150 feet above the Arroya Seco and have provided a romantic setting for many couples.

When construction began in 1912, engineers faced several hurdles.  The slopes on both sides were steep and the arroyo bed was seasonally wet; however, engineers created a work-around by curving the bridge 52 degrees to the south and using massive archways to help reinforce the concrete structure.

To support the concrete bridge, the designers used a spandrel construction with support columns holding up the arched ribs of the bridge. In total, over 11,000 cubic yards of concrete and 600 tons of steel were used at a cost of $235,000.

The bridge was used to connect Pasadena to LA, but by the 1930s it was already overrun and insufficient for the city’s needs. After falling into disrepair in the late 80’s, and eventually closed after the Loma Prieta earthquake in 1989, the bridge reopened to the public in 1993 after renovations.

Today, the bridge is open to cars and pedestrians. Visitors can come and admire the design, concrete, and steel that have kept this bridge in use for over 100 years.

With award season in high gear, La La Land is poised to bring home quite a few statuettes. Behind the songs, love, and heartbreak sits the city of Los Angeles bathed in bright lights and decorated with some of the most beautiful buildings of 20th century America. Thanks to the steel holding them together, these structures have endured time, earthquakes, and multitudes visitors.
