 Product Information:

JBG-50 Rebar Thread Rolling Machine is designed for processing parallel threads for rebar mechanical connection in construction. It can process HRB335,HRB400 and HRB500 hot rolled ribbed reinforced bar with diameter 12-50mm. In addition to all features of all above types, it is our patented product developed in January 2009, the effective thread length could reach 120mm in maximum.

The Machine is especially fit for long rebar thread processing and large diameter rebar in bridge and tunnel. At the same time,it makes up the shortfall that 40 type rebar thread rolling machine could not process rebar with diameter 12mm and 50mm.
