ebar thread rolling machine is developed according to the market demand. It is the key equipment to realize the splicing of reinforcing bars.It is mainly used for the processing of parallel thread head of ribbed reinforcing bars in bridge and reinforcing cage piling construction projects. It can process the ribbed bars from HRB335-HRB600 with diameter12-50 mm. The parallel thread rebars processed by the rolling machine will have good comprehensive mechanical properties with the continuous and compact metal fibers. Tensile Strength: increased by 20%-30%; Fatigue Strength: incread by 40%ï¼?60%, Corrosion Resistance: increased by 50%-200%; The strength of steel bar joints is higher than that of steel bar base materials. The mechanical properties of steel bar joints meet and exceed the domestic and international standards.
