Korea’s steelmaker Hyundai Steel has introduced its new reinforced, earthquake-resistant steel bar, which the steelmaker is expected to make strong inroads in the market as demand for quake-resistant construction has been on the rise after a series of earthquakes struck Korea.
"Hyundai Steel has completed development of steel deformed (SD) 500 and 600 quake-proof steel bars for the first time in Korea and is ready to kick off mass production," the company said. SD500 steel bar can withstand 50 kilograms per one square millimeter.
The company also said that it will receive KS certificate by the end of 2016. The reinforced steel bars can withstand more shocks from the outside and reduce deflection, making them more reliable. In addition, the new, improved steel bars will give more time to evacuate during earthquake as the entire building can absorb shocks more efficiently in a structural fashion.
Earthquake-resistant structural steel has been gaining much attention these days after a swarm of quakes in Gyeongju and other nearby North Gyeongsang Province regions. The new law requiring incorporation of seismic design to a building with two or more stories from next year will add some momentum to soaring demand growth of quake-proof structural steel, too.
“The domestic market for quake-resistant structural steel is just beginning to expand and utilization remains low,” Hyundai Steel said. “We will focus on market expansion while stay committed to introducing upgraded products as a leading company with an unmatched reputation.”
Hyundai Steel came up with Korea’s first quake-proof H beam in 2005 and commenced research on its development of quake-resistant steel bar in 2011. Two years later, the steelmaker released SD400S, Korea’s first commercial quake-resistant steel bar, and supplied it for the construction of the new office building of Korea Electric Power Corporation Engineering and Construction.
