what is rebar coupling

In reinforced concrete structure longitudinal rebar connections are provided to ensure continuity of reinforcement. The reason that this requirement arises is the limitation in availability of a standard length of rebars. Due to transportation limits, the rebar length is normally restricted to 12 meters. In structural members, where reinforcement required length is longer than … [Read more...] about Rebar Coupler vs Lapping – Why Rebar Couplers are More Efficient and Economical?
