This type of coupler is used in place that at least one of rebars is able to be rotated. Internal thread of the coupler is right hand and complete part of thread on the rebar shall .be fastened inside the coupler. SAHAND produces this type of coupler from 16 mm up to 50 mm and any other request of customers is possible For the production of coupler solid steel bar (DIN 1.1191) is used as raw material.Universal and CNC machine tools is used in production line.e At each stage of production ,QC department controls coupler specified dimensions and after confirmation of complete manufacturing process in the first step the couplers are transferred to the next step. The couplers quality meets the Iran national building regulations and international codes and standards such as ACI 318, DIN1045 and BS 8110.0
1-First move the plastic protection cap of rebar threads,then fasten the coupler on the threads by hand.
