Description

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
