Hyundai Steel has become the first company in South Korea to obtain Korean Industrial Standards (KS) certification for structural H-beams designed to withstand both earthquakes and fires. The company plans to improve building safety and construction efficiency with high-performance steel products that combine seismic resistance with fire resistance.

Hyundai Steel announced on Nov. 12 that its SHN355FR fire- and seismic-resistant structural H-beam had received certification under KS D 3866 (Hot rolled steel sections for building structure).

SHN355FR is a steel product with a yield strength of 355 megapascals (MPa), offering the deformation capacity and seismic resistance required during earthquakes. In particular, even when the steel temperature rises to 600 degrees Celsius in a fire, it retains at least 67% of its yield strength at room temperature, helping maintain the structural stability of buildings.

As buildings become taller and larger, the importance of construction materials capable of withstanding multiple types of disasters has grown. Against this backdrop, Hyundai Steel has focused on developing fire resistance based on its existing seismic-resistant steel technology. With the latest certification, the company has gained official recognition not only for its product performance but also for its manufacturing and quality management capabilities.

Hyundai Steel expects that applying the steel to construction projects will enhance safety against fires and earthquakes while reducing the amount of fireproofing materials required and simplifying construction processes. The company also anticipates economic benefits, including shorter construction periods.

A Hyundai Steel official said, "Obtaining South Korea's first KS certification for SHN355FR is an achievement that officially recognizes our fire- and seismic-resistant steel technology and manufacturing capabilities accumulated over many years." The official added, "We will contribute to creating safer building environments through continuous research and development and improvements in product quality."
