POSCO’s World Premium Products (WPP) and solutions were used in the main facilities of the 2018 PyeongChang Winter Olympics. POSCO’s products can be found in the recently-completed International Broadcasting Center, Media Residence and Kwandong Hockey Centre that boasts increased durability, stability, surface quality and sustainability.
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.
