Threaded Coupler

SBT couplers is a parallel threaded system for reinforcing bars dia 16 mm. to 40 mm diameter.They produce full strength joint in the rebar connection. The ends of the reinforcing bar to be jointed are cut square and then enlarged by cold forging process to increase their core diameters to ensure that the joint is stronger than rebar. The couplers are usually supplied attached to the reinforcing bars.The end of the reinforcing bars to be jointed is sawn cut The sawn cut ends of the reinforcing bar is then enlarged by cold forging process to increase its core diameter.
Standard metric thread is then cut onto the enlarged end.
Finally splice the rebar by using SBT parallel threaded couplers
