rebar coupler

rebar coupler 1. Easy Operation, saving time and rebar material. The rebar coupler producing and rebar end threading will not be affected by the weather; It can be processed before processing. 2. It can connect the rebar with the diameter 14mm to 40mm. 3. Use No. 45 steel, with the thickness and length of the rebar coupler, the connecting part has higher tensile strength than the rebar part Processing step: 1: The ends of the bars to be joined are cut square and enlarged by cold forging to increase their core diameter and so ensure that the joint is stronger than the bar. The couplers are usually supplied attached to the reinforcing bar. 1. First use the upsetting machine to thicken the end of the rebar end, 2. Then use the steel bar threading (cut) machine to make thread on the end of rebars. 3. Connect the two rebar end with the upsetting rebar couplers.
