However, it seems the world just can’t get enough of water. Global water demand is projected to increase 55 percent by 2050. Most of the demand will be driven by the agriculture industry, which currently makes up 70 percent of freshwater consumption, but is projected to grow another 69 percent to meet the food demands of the growing population. New-growth industries will put additional pressure on freshwater supplies. For example, water used to cool power stations is projected to increase by more than 20 percent by 2055 and water demand from the manufacturing industry in developing nations will grow by 400 percent by 2055. Unfortunately, 97.5 percent of earth’s surface water is inadequate for human use.

The growing demand is putting heavy pressure on current water supplies that appear to be shrinking due to global warming and climate change. As a result, there have been extensive efforts by individuals and households to conserve and recycle water. However, in major cities around the world, water is wasted before it even reaches people’s taps.

Water leaking through the cracks

In the U.S., about 2.1 trillion gallons of water slip through the cracks, literally, each year, or about 6 billion gallons of water per day. The ancient water infrastructure throughout the country is full of leaking pipes, cracked mains and broken meters.

For example, the largest water filtration plant in the world, Jardine Water Filtration Plant, is located in the city of Chicago and pumps out purified water to about 5 million residents via thousands of miles of pipes. However, about 22 billion gallons of water leak through old pipes and broken water mains in the city every year. In Philadelphia, the Water Department pumps out 250 million gallons of purified water daily to nearby residents, but more than 60 million gallons are lost through the pipes every day.

In Canada, home to some of the most abundant supplies of freshwater, there are cities with 35 to 45 percent water loss. Ontario, for example, has outdated and leaky pipes responsible for the loss of about  CAD 700 million per year in wasted drinking water.

In the UK, about 872 million gallons, or 20 percent the nation’s treated water supply, leaks through old pipes before it reaches residents. This is 62 million gallons more per day than water loss rates from a decade ago, showing the severe consequences aging pipes can have.  

Faulty water pipes

The biggest problem with water systems around the world is simply their age. They were built ages ago, often with insufficient materials and outdated technology, and now, they’re too expensive and extensive to repair or replace.

However, old pipes can pose a number of problems. Besides the gallons of wasted purified water, an outdated water system can pose major health risks. In the U.S., 1 in 4 people drinks unsanitary water due to insufficient water infrastructure. It has already been proven that contaminants can enter the water system through leaks that are most often caused by corrosion and material defect.

Water pipes installed decades ago are traditionally made of cast iron and laid on wooden blocks or rocks. Such pipes are highly corrosive and most susceptible to damage. Also, a well-functioning pipe keeps contaminated water out with pressure from mains that forces water out of minor cracks, but not in. Over time, damage to a certain section of a pipe can cause this pressure to drop, and groundwater often finds its way in through cracks.

Making it right with steel

The ideal solution for outdated, faulty water pipes would be to replace them with new ones equipped with the latest damage detection and repair technologies. However, such projects are not only expensive, but a city’s water system is often politically, regionally and physically intertwined with other entities, making it difficult to take on such a mammoth task.

Thus, cities opt for isolated repairs instead, either placing a stainless steel clamp over the damaged area or inserting a smaller stainless steel pipe inside the existing, cracked pipe. Stainless steel is the most common material for repairing and replacing outdated cast iron, concrete and lead pipes due to its excellent strength and resistance to corrosion. Higher grades of stainless steel, such as POSCO’s PossSD, can also resist high levels of pressure and are naturally resistant to microbes. Stainless steel can also be manufactured to withstand extreme temperatures.

Major cities such as Tokyo, Seoul and Taipei are undergoing massive projects to replace the majority of their water pipes with stainless steel to ensure safe and abundant drinking water for residents. For other cities, repairing leaky pipes with stainless steel will save millions of dollars currently leaking through the pipes and prevent illnesses associated with contaminated water. As the global demand for water continues to grow and fresh water supplies continue to shrink, conservation is becoming more important than ever, ensuring that stainless steel will play a vital role in water pipe repairs and replacements for years to come in efforts to correct and maintain the system that serves the basis of all human activities.

The U.S. is headed towards a major shortage of truck drivers. (Source: The New York Times)

However, the U.S. is short of about 30,000 to 35,000 drivers for every 750,000 trucks, and the number of driver shortages may reach up to 245,000 by 2022. That’s because right now, the average age of truck drivers in the U.S. is 55, and potential new recruits are choosing to sign up for construction or manufacturing jobs instead.

All this leads to climbing prices for freight transportation. Last December, at the peak of holiday deliveries, U.S. companies saw the highest monthly average rate for freight transportation since 2010. The high operation costs and lower profit margins are putting a heavy strain on industries. Heading into 2018, companies have to compete for carriers as there is just one truck available for every 12 loads.

As a result, Major automakers are heavily invested in autonomous electric freight trucks such as Tesla, Volvo and Daimler, and there are many proponents of an eco-friendly, safe and driverless future for freight transportation. However, autonomous freight trucks are not a realistic option for companies just yet. At a time of transition between the old and the new, there is a serious lack of capacity in freight transportation, and companies are left to deal with the higher costs for delivery.  

But good news right around the corner

Although the driver shortage is a major concern, it is a natural phenomenon in the transition towards a safer, more sustainable and more efficient freight transportation industry.

Already, Uber has its autonomous trucks on the highways of Arizona. Every truck does have a human driver present to take over anytime, and the company uses transfer hubs to transfer goods between highways and local roads. Autonomous trucks are the safest and most efficient for use on highways, so human drivers transport goods from highways to the final destination. The company is working to operate without human backup drivers in the near future.

Speeding up delivery

Numerous other automotive and tech companies besides those mentioned above are getting ready for autonomous freight transportation. The faster autonomous freight trucks are able to operate commercially, the faster industries can cut costs, improve delivery times and reduce their carbon footprint.

This means software technology, high-capacity batteries as well as the right automotive materials will play a crucial role in the future of the freight transportation industry, as well as in related industries. This transformation will open up new business opportunities for automakers, software companies as well as steel manufacturers like POSCO.

For autonomous truck manufacturers looking for ultra-lightweight yet super strong materials for optimal fuel efficiency, POSCO developed POSCO GIGA STEEL. The advanced high-strength steel (AHSS) material is 3 times stronger and 3.5 times cheaper than aluminum. Steel is also 100 percent recyclable and an electric vehicle made of AHSS requires 30 percent less energy than aluminum throughout its entire lifecycle. POSCO also developed a premium non-oriented electrical steel called Hyper NO for the most advanced and sustainable electric motors.

POSCO also works with its auto partners to research and provide customized technology and materials solutions for their autonomous EVs. In the midst of a critical shortage of truck drivers, POSCO hopes to speed up autonomous EV adoption both for personal and commercial transportation and aid the transition into a more efficient and environmentally sustainable economy.

Over the years, Game of Thrones has become more than just a show, but also a cultural movement, as fans have fallen in love with everything Game of Thrones related. As a result, HBO has partnered with numerous breweries to create special-edition beers, and the show’s jewelry designers even opened up their own online store. Another surprising consequence of the show’s popularity is the increasing number of people taking up an interest in blacksmithing to make replicas of their favorite swords and weapons from the show.

The Blacksmiths of Today

Although blacksmiths are rare to come by today, in the 18th and 19th centuries, they were a vital pillar of society. Blacksmiths hand-produced everything made of iron and steel, from pots and farming tools to swords and shields. They forged life’s necessities out of the hot metals, right up to the industrial revolution.

Traditionally, only young men were eligible to become blacksmiths once they completed a 7-year paid apprenticeship. Apprentices worked for established blacksmiths who would in turn house, feed and train them. Today, women can also become blacksmiths and there are various training and education programs available for aspiring blacksmiths.

Modern blacksmiths do not hammer away to produce tools and weapons out of necessity, as machines are far more capable and efficient. Instead, they turn out beautiful pieces of art such as sculptures and unique knobs and bolts. And, the growing popularity of Game of Thrones has more young people pursuing the art as a hobby and a profession.

The Artist Blacksmiths Association of South Australia has reported a growing number of young adults who want to take up the art as a result of the show’s growing popularity. Most of the props in movies for war scenes and superheroes are crafted by hand, and fans want to replicate their favorite characters’ swords, shield and armor.

Blacksmithing for Dummies

So, for all you Game of Thrones lovers, or just plain ol’ steel junkies, here are the basics to get started in the craft. Get a piece of iron or steel, heat it, pound it into shape and cool it down. It sounds simple, but it takes a whole lot of sweat, patience and know-how to do it right.

Heating

Having a good source of heat is vital for blacksmiths, and most opt for a coke or propane forge (or oven). Steel is heated repeatedly to make a single object, so blacksmiths have a forge that is always hot and ready. Blacksmiths also commonly use an acetylene torch to apply heat to isolated areas to achieve specific designs.

Holding

An anvil looks like a big block of steel, and its the bedrock on which blacksmiths create their masterpieces. The quality of the anvil will affect not only the quality of the final product, but also the amount of physical labor required by the blacksmith. Tool steel is one of the best kinds of anvils available as it is extremely hard. Instead of absorbing energy from the blow of a hammer, it forces the energy back up the piece of metal being worked.

Besides providing a flat surface, or face, for blacksmiths to pound away on, an anvil has many different features and functions. Blacksmiths also use the anvil to cut, shape and hold the piece of steel being worked along with tongs and clamps.

Hitting

The actual “work” entails a lot of hitting, but in a very calculated and practiced way. Blacksmiths use different types of hammers to pound the metal into various shapes. The 3 most basic techniques are drawing out, upsetting and peining. Drawing out a piece of hot steel means to make it longer by hammering the sides. Upsetting refers to adding force to one end of a hot piece of metal to add volume. Piening means to hammer the piece of steel to move it in a particular direction or to spread it out thin. Blacksmiths use tongs or other specialized tools to hold down the hot steel on the anvil while hammering and working the steel into shape.

Quenching

After countless cycles of heating and hitting, the blacksmith will end up with the desired shape. The final step is to dip the work into a bucket of cold water to cool and harden the steel.

With the above basics, and all the accompanying safety gear, anyone can pick up the craft as a hobby to create unique pieces of steel art, or replicas of the greatest swords of Westeros.

POSCO values the contributions from its female workers and their role in its success. In the past, The Steel Wire has looked at women in the steel industry as well as a few of the women who have had a lasting impact at POSCO. Please check out the in-depth interviews with Yukyung Lee, Group Leader of Iron Ore Group of the Raw Materials Department; Mihwa Park, Head of the Information Planning Department; Young Choi, Vice President of PR at POSCO Daewoo; and Lee Yoon Hee, Vice President of POSRI.

Today, in honor of International Women’s Day, we want to take a moment to celebrate three women who broke barriers in their own male-dominated fields. Their hard work, perseverance, and dedication allowed the world to recognize and acknowledge the capabilities of women.

Alice Peurala, Woman of Steel Who Fought for Gender Parity in Steel Industry

Women have long been a minority in the metals and mining industries (Catalyst noted in 2015 it was at just 13.3% in the U.S.). However, thanks to the efforts of women like  Alice Peurala, many more rights and protections are afforded to them today.

Alice Peurala, the first woman to head a steel unit, played a vital role in the steel industry during WWII. Peurala was one of the first female steelworkers who entered Chicago’s South Works mill in 1953 when there were only a few women left in the field. Most of the women who had steel jobs as a result of WWII had been let go when the men returned home. Those who remained, including Alice Peurala, faced gender discrimination in hiring and promotion. Having been an activist in the civil rights movement, she was determined to transform the steel industry into a more comfortable workplace for female employees.

“I did not win as a woman. I campaigned as a candidate who would do something about conditions in the plant that affect 7500 people – men and women.” – Alice Peurala

When Peurala was denied a promotion from her job in the Metallurgical Division to a job in a product testing lab in 1967 because people thought she was ineligible for a job that required overtime and heavy lifting, she sued the mill at the recommendation of the Equal Employment Opportunity Commission (EEOC). Due to her unwavering efforts, a compromise settlement was reached and in 1969, Peurala finally got her promotion. Her successful lawsuits against gender discrimination and the dictatorial control of the steel company owners were indeed a victory for all women in manufacturing. Alice eventually won the presidency of the Local 65 in 1979 and left an impressive legacy as a fighter for women’s rights.

Raye Montague, The First Person to Design Computerized Ships for Navy 

Raye Montague, the first female Program Manager of Ships in the U.S. Navy, not only shattered the glass ceiling as a black woman in the then male-dominated Navy but also the first person who single-handedly changed the way the U.S. Navy designed and used ships.

Growing up, she was often ridiculed for wanting to become a female engineer and was even denied entry into the University of Arkansas because the school did not allow minority enrollment at that time; however, she did not let gender or race barriers discourage her.

She taught herself how computers worked and rose in the ranks for 14 years to become a computer systems analyst at the Naval Ship Engineering Center.  In 1970, she showed the world that women were just as capable as men in the male-dominated Navy by revolutionizing the design process for all naval ships and submarines – a task she famously completed under 19 hours even though she was given a month by her boss.

Montague retired in 1990 and entered the Arkansas Black Hall of Fame in 2013. After the award-winning film Hidden Figures was released, which tells the true story of three African-American women who helped the U.S. space program at NASA, Montague appeared on Good Morning America and sparked interest in her story as another true “hidden figure” during that same era, whose dedication and unwavering commitment became an inspiration to all women.

Billie Jean King, Breaking Records and Gender Barriers

Long a champion for social justice and gender equality, Billie Jean King is a 39 time Grand Slam winner and an American former world #1 professional tennis player. She transformed the world for not only female sports players but also for the LGBT community.

In 1973, King famously threatened to boycott the U.S. Open unless the winner of the ladies singles was awarded the same prize money as the men’s champion. Thanks to her efforts, the U.S. Open became the first major tournament to offer equal prize money to women and men.

That same year King famously defeated men’s former world No.1 Bobby Riggs in a match later dubbed “Battle of the Sexes” in the Houston Astrodome proving to the world that women could compete with men in any arena. In the most viewed U.S. tennis match of all time with more than 50 million Americans tuned in to watch, King beat Riggs, 6–4, 6–3, 6–3 for the USD 100,000 winner-take-all prize. More importantly, the match turned King into arguably the first superstar female athlete in the U.S. Later this year Emma Stone and Steve Carell will adapt this story for the big screen, helping to reignite the excitement of King’s win in 1973.

King also became the first prominent female athlete to come out as gay in 1981 and continued to advocate for gender equality and the LGBT community even after leaving tennis in 1983. In 1990 was named one of the “100 Most Important Americans of the 20th Century” by Life Magazine and in 2009, she was awarded the Presidential Medal of Freedom, the nation’s highest civilian award for her massive contribution to improving gender equality on the tennis court.

King’s demands for equal treatment and equal pay helped pave the way for future stars such as Chris Evert, Steffi Graf, and Serena Williams, the latter who broke barriers of her own at the 2017 Australian Open by winning her 23rd Grand Slam singles title, the most of any player in the Open Era.

“It’s not about the money, it’s about the message we send. We are sending the equality message out that this is the right thing to do. Yes, the men are better than us in some ways. Yes, we’re better in some ways. It doesn’t matter. Don’t you want to share in this world? I do.” – Billie Jean King

On International Women’s Day, POSCO honors these three remarkable women who made major contributions in their fields at a time when female participation was incredibly difficult. The bravery and dedication of these women, along with so much more around us who have broken through barriers to ensure gender equality are, and will continue to be,  a source of inspiration for all.

While some believe modern architecture is a result of social and political revolutions, others believe it is a result of technological and engineering advancements. No matter which perspective you share, steel has been a part of the construction of homes since the 1920s. Because steel is lightweight and adaptable, it is the perfect material for sturdy frames that are eco-friendly and long-lasting. Steel is also energy-efficient and recyclable. Steel outlasts other building materials, offering improved safety and resistance to wear and mold.
