BGZL-40B3 Rebar Rib Peeling Thread Rolling Machine is used for rebar mechanical splicing in construction work. When the machine is running, the rebar ribs are peeled first, and then parallel threads are rolled on rebar end. The two processes are completed only once, making the processing speed fast, the thread quality high and the operation stable. Machinable rebar with diameters from 16mm to 40mm.
