POSCO started supporting the team last year after CEO Ohjoon Kwon watched the team take the bronze medal at the 2017 World Championships. As shown in the documentary, the athletes were playing on insufficient sledges that would often break down and cause injuries. Some players were fixing their own sledges between matches, others made do with what they had. CEO Kwon knew POSCO had the solutions for the team and started a project with sledge-maker Massive Blade to revamp the sledges for the team. Now, ahead of the 2018 PyeongChang Winter Paralympics, the team is equipped and ready with the world’s leading technology.

Parallel: A Documentary

Parallel was directed by Kyungman Kim in 2012. He wanted to make the movie to document the para ice hockey players’ endurance and grit in overcoming their physical limitations through the sport. “However, as I started editing the footage and putting it all together, I noticed how happy the players looked on the ice. That’s when I decided the documentary was going to be about happiness – what it really means to be happy. That’s what I want to share with viewers,” said director Kim.

That’s exactly what the movie delivers. Of course, the players face challenges every day due to their injuries and physical conditions, but the interviews in the documentary reveal the players to be genuinely happy and grateful for their sport. Seunghwan Jung, one of the players, says, “I used to wish I had legs all the time, but when I started playing hockey, the thought just never crossed my mind. In a way, the sport has allowed me to accept myself… understand myself.”

For many of the players, playing para ice hockey has been a healing process, but it doesn’t end there. The team is as competitive as any other Olympic team, and even with a lack of spectators and interest in the sport, the national team has produced impressive results. In the 2010 Vancouver Winter Paralympics, the team placed 6th, and then 7th in Sochi in 2014. This is even more remarkable given the poor equipment, especially the sledges, they were using at the time.

POSCO Gives Ice Sledges a Technological Makeover

In order to qualify as a para ice hockey player, a person must have a physical impairment in the lower part of their body, but this can come in many different forms. As a result, one of the biggest challenges teams face is finding sledges that fit, protect and enhance each player. Before POSCO signed on as a sponsor, the Korean National Team relied on expensive imported sledges from Canada that were heavy and susceptible to structural damage from harsh contact. On average, 5 to 7 sledges required repair work during a single game. In an attempt to produce the first domestic sledge, POSCO’s researchers jumped on board to provide sledge-producer Massive Blade the materials for a lightweight, strong and corrosion resistant sledge.

Researchers at POSCO’s Research Institute of Industrial Science & Technology (RIST), came up with a way to use magnesium as the main material for the sledge frame. Magnesium is one of the lightest materials available as it is one third lighter than aluminum, but it is extremely hard to treat and bend into shape. RIST not only developed the technology to treat magnesium, but also applied it to sledges for the first time in history. POSCO also provided its advanced high-manganese anti-vibration steel and stainless steel to finish off the new sledges, fit for a national team.

RIST researchers developed a processing technology to increase the moldability of magnesium.

Outfitted with the new sledges, the team beat out strong European teams in the 2017 World Championships to place 3rd, and just last month, they won a four-nation friendly tournament in Japan. Now, they have their eyes on an Olympic medal in PyeongChang.

Regardless of the results, POSCO will continue to support the Korean National Para Ice Hockey Team so they can continue doing what makes them and others around them happy.

The budget for the entire event was estimated to be around USD 10 to 13 billion to get PyeongChang in prime shape to host more than 6000 athletes and officials from all over the world. As a result, the winter games will take place in 13 different venues, 6 of which have been newly built and the remaining 7 were renovated specifically for use during these games.

International Broadcast Center

This year’s Winter Olympics will set a new record as the first Olympics to be broadcast live in all U.S. time zones, and all of this will be coordinated through the IBC. POSCO custom-made H-beams for the center’s pillars and columns using Pos-H, a type of steel produced by precisely cutting and welding POSCO’s hot-rolled steel plates and thick plates together.

The HSA5-based Pos-H is seismic wave resistant and can be customized to fit specific height and thickness requirements for different parts of a building. Plus, compared to existing hot-rolled steel which only comes in a standard size, manufacturers have the added benefit of reducing the amount of steel used, thus saving costs.

POSCO also applied GI-Ace steel and fire-resistant cladding to the IBC’s columns to not only increase fire resistance but reduce construction time. POSCO’s dry fire-resistant cladding is different from traditional methods that require numerous layers of fire-resistant paint to be applied, requiring additional manpower and hours to complete. Dry-cladding can be wrapped around the surface of the columns in a one-time process.

Finally, the 5-story IBC is now capable of supporting a much larger load thanks to a new composite beam with concrete integrated into POSCO’s SM490 steel. Overall, POSCO supplied 8,218 tons of steel for the IBC.

Media Residence Hotel

The Media Residence Hotel is another important facility POSCO’s materials and construction solutions played a vital role in. POSCO wrapped the exterior walls of the 300-room, 4-story building with PosMAC, a magnesium alloy coating, that is 10 times more corrosion resistant than standard galvanized steel.

The interior walls are also lined with steel. Instead of wallpaper, the Media Residence Hotel is lined with a special type of printed steel that feels like fabric to the touch. POSCO also applied PosMAC to the modular bathroom floors instead of traditional tiles. PosMac is 5 times more corrosion-resistant than zinc plating, and has an aesthetically-pleasing finish. POSCO’s stainless steel, PossSD, made up other parts of the bathroom as it is also highly corrosion-resistant and workable. In addition, each entrance was made with POSCO’s high-strength and corrosion-resistant 329LD duplex stainless steel with surface treatment and color processing.

What’s noteworthy about this construction project is that 100 percent of the building was constructed off-site via modular construction. Compared to the time it would take to build a traditional concrete building of the same scope, the construction period for the Media Residence Hotel was 18 months shorter. Since each room is a relocatable building unit, it will be moved to a different venue and recycled as another hotel or dormitory. All in all, POSCO supplied 1,405 tons of steel for the entire construction project.

Kwandong Hockey Center

Kwandong Hockey Center will be home to some of the most exciting action of the winter games, and the facility was built on the “ice wave” concept to reflect the dynamics of ice hockey, waves of the nearby East Sea and the region’s strong winds.

Again, POSCO’s duplex stainless steel 329LD was used to cover the stadium’s exterior to protect against rapid corrosion that is prevalent in coastal areas. Aside from protection against corrosion, the stainless steel is extremely high in strength, allowing the builders to reduce the thickness of the steel plates by 25 percent compared to standard types of stainless steel.

POSCO also aided the construction process by providing additional support such as internal wind pressure structural analysis, surface treatment and a panel processability evaluation to maximize the benefits of POSCO’s products.

With these new and upgraded facilities completed, PyeongChang is now equipped and ready to host the 23rd Winter Olympics. The only thing left to do now is to witness history as the best athletes from all over the world compete for gold. Best of luck to all the Olympic and Paralympic athletes!

For the International Broadcasting Center (IBC) completed last April, builders used POSCO’s Pos-H steel. Building parts were made by precisely cutting and welding the hot-rolled steel plates and thick plates. Pos-H is custom-made for structures and does not produce any waste unlike existing hot-rolled shape steel with fixed dimensions. In addition, POSCO’s dry fire-resistant cladding technique was applied to all the pillars of the IBC. The dry fire-resistant cladding technique eliminates the process of applying fire-resistant paint to pillars for fire prevention, and instead, fire-resistant materials are wrapped around the pillars.

The Media Residence that will house reporters during the PyeongChang Winter Olympics resembles a steel showroom due to its impressive design. PosMAC, which is over 5 times more corrosion-resistant than general galvanized steel sheets as it is coated with zinc, magnesium and aluminum, was specially printed to bring to life the fiber texture. PosMAC was used for the exterior of the bathrooms and walls for durability as well as artistic value. The surface steel plates plated with aluminum and zinc, called ALZASTA was treated to achieve a glittering spangle pattern texture and applied to the residence fire doors, valve enclosures and hallways. PossSD, stainless steel with a level of reflectivity equal to that of a mirror, was used inside the bathrooms.

The Media Residence was completed on December 15, after 8 months of construction. All of the 300 rooms were prefabricated in a factory and assembled at the site. This is known as modular construction. It reduced the construction period by 18 months compared to building with general concrete. More than anything else, modular construction makes it possible to move the structure to another location and reuse it. In this respect, modular construction is regarded as the best choice for the facilities that will be removed after the Winter Olympics. The Media Residence will be reused as a hotel or dormitory.

Finally, the Kwandong Hockey Center’s exterior walls are made of 329LD POSCO stainless steel, which is highly corrosion-resistant and robust. POSCO provided the structural analysis by calculating the optimal thickness for the walls and reduced the thickness by 25 percent.  

After the PyeongChang Winter Olympics and Paralympics, POSCO will continue to provide construction solutions through is WPP and technologies for its partners.

So, what do these athletes from all over the world competing in various different sports have in common? They all rely on steel to enhance their performance and keep them safe while they compete for the highest honors in their profession.

Here are some of the most prominent ways steel plays its part in winter Olympic sports:

Blades/Edges of Steel

Ice Hockey

Ice hockey is easily the main attraction of winter Olympics as hockey finals are usually the last events of the Games. The same can be said of para ice hockey as well. Athletes glide through the rink on specially-made sledges, or sleds, and have as much, if not more, full-contact than regular ice hockey.

There are several pieces of equipment that enable hockey players to perform at their best, including their skates and sleds. The deciding factor in the quality of skates comes down to the type of steel used in the blades, or runners. Harder types of steel are preferred for less wear and tear and so that athletes do not have to sharpen the blades too often.

That’s why most opt for stainless steel, for its high-strength, hard, ductile and corrosion-resistant qualities. For para ice hockey players, their sleds make or break the game, and materials like magnesium, high-manganese anti-vibration steel and stainless steel give them the edge they need.

Figure Skating

Blades on figure skates look similar to that of hockey skates, but are longer and heavier. Figure skate blades also have the thickest type of blades at 4 to 5mm. These blades were most commonly made of tempered carbon steel coated with chrome, but lighter materials such as stainless steel are becoming more common. At the professional level, many athletes wear skates with high-grade steels that are much more expensive than common skates. A distinct characteristic of these blades is the spiked front toe which gives figure skaters the traction they need for rigorous jumps and spins.

Short and Speed Skating

Like blades for hockey and figure skates, short track and speed skates are also made of stainless steel. Short track skates are slightly curved and shorter than speed skates, with slightly rounded backends for safety.

Speed skates are different from those for short track because the back-end of the blade is detached from the boot. this reduces friction and energy loss. Also, the detached blade allows the blade to remain attached to the ice longer than attached blades.

Skiing and Snowboarding

Steel also plays a crucial part in the construction of ski and snowboard edges. With high-quality steel, athletes can sharpen the edges more frequently, and sharp edges are crucial for carving and turning on snow. Edges are most commonly made of stainless steel, and they are inserted into the body of the ski or snowboard via “teeth” or T-shaped ridges. Most edges have a Rockwell 48 hardness.

Rock-hard Skeleton, Ultra Sharp Blades

Bobsled

There are several variations of bobsled events during the Olympics: 2-man, 4-man and women’s doubles. No matter how many people are on a team, each bobsled has a steel chassis or skeleton and four steel blades attached to the bottom of the sleds. Every team must use the same type of steel for blades used in competition. Much like a car, materials that make up the bobsled must be lightweight yet strong so the athletes have the freedom to steer through the track. During competition, sleds slide through at an average speed of 150 km/hr.

Luge

The luge is considered to be the most dangerous winter Olympic sport due to high speeds and sharp turns of the track. After push off in a seated position, the person or pair lies flat on their backs and steer the sleds with their bodies. Sleds have a pair of steel blades attached to the bottom. Olympic rules prohibit teams from heating the blades before competition as it would decrease friction against ice. Instead, athletes try to maintain the sharpest blades possible.

Skeleton

Opposite of the luge, skeleton athletes race flat on their stomachs, with no brakes. Instead of starting on the sled, the athletes have to sprint for about 40 meters before hopping on. All skeleton sled frames must be made of steel, and blades are usually made of high-quality stainless steel. As for all the “sliding” sports, there are strict rules for the size and weight of the sleds.
