Steel bar for concrete
reinforcement is generally called rebar and widely used in construction & civil engineering. Today, most structures (such as building, bridge and etc.) are constructed using Steel, Reinforced Concrete or Pre-Stressed Concrete. As concrete is strong for compression but weak for tension,
rebar in the concrete will increase resistance against exterior stress. KOSTEEL
manufactures Steel bar for concrete reinforcement of 10.0 ~ 13.0 mm with highest quality in accordance with quality standard specified in KSD 3504.
