Threading Rolling rebar coupler

Standard rebar couplers made by raw material 45# carbon steel with competitive price and divided into standard couplers, positional rebar couplers, and transition rebar couplers

1. Standard rebar couplers Introduction

Standard rebar coupler belongs to Rolling technology, it is a parallel-thread mechanical splicing system used for the 16mm to 40mm reinforcing bars mechanical connections. This system is first peeling the rebar rib and then doing thread by cold rolling, this technology can meet with China standard of JGJ107-2010, USA standard of ACI318, UK standard of BS8110, VN standard of TCVN8163, and other international standards. The couplers can be divided into standard couplers with all right-hand thread, and also positional rebar coupler with one side left-hand thread another size right-hand thread, also it has transition couplers which two sides have different diameters. Also, this coupler has a competitive price over super couplers and is suitable for little lower rebar grades such as HRB400 or HRB500 rebar, it has full sizes from 16mm to 40mm.
