What are Reinforcement Coupler's Reinforcement Coupler's are used to join Reinforcement bar's that are used in Reinforced concrete structures, as a replacement for conventional lapping method of joining Reinforcement bar's. Mechanical Splice / Coupler's are  mechanical connections between two pieces of reinforcing steel that enable the bars to behave in a manner similar to continuous lengths of reinforcing steel bars. Mechanical splice join rebar end-to-end, provides many advantages of a continuous piece of rebar. Mechanical Splice  system is used in connecting Reinforcement Bar of respective/ different diameter using the respective Coupler's as per applications and standards/criteria.
