Posco has utilized its advanced steel technology to transform traditional sites in Seoul into vibrant public art and relaxation spaces as part of South Korean cultural heritage restoration. The centerpiece of this endeavor is PosART, an innovative steel sheet developed from Posco Magnesium Alloy Coating Product (PosMAC), which is Posco's proprietary corrosion-resistant steel. PosART offers high-resolution printing technology that can render vivid colors and delicate textures, surpassing the capabilities of conventional steel sheets. Last August, Posco Group and the Korea Heritage Service collaborated to improve the design and structural integrity of restoration sites. The use of PosART at these sites has been a significant departure from the typical plastic panels, providing both aesthetic appeal and promising durability. The Seonwonjeon area of Deoksugung recently unveiled an art fence utilizing PosART, attended by KHS chief Choi Eung-chon, US Ambassador to South Korea Philip Goldberg, and Posco's director of steel products for construction marketing Oh Do-gil. The fences, adorned with designs inspired by historical flora, were created by photographer and Royal Palaces and Tombs Center Ambassador Lee Myoung-ho. Posco plans to expand the application of their technology and steel products to restoration projects at Gyeongbokgung and other cultural sites, while also extending the use of PosART in public infrastructure, such as the installation of comprehensive information guideboards for Seoul Trail 2.0 in collaboration with the Seoul Metropolitan Government. These guideboards, incorporating PosART for improved visibility and durability, were strategically placed at six key points along the trail, including Maeheon Citizen's Forest and Hwagyesa Temple.
