ERW tubes and cold roll-forming profiles are rolled by several mill stands and bended by different grooves of mill rolls. The quality of ERW tube rolls and cold roll-forming profiles will directly effect the quality of products and output of products.Hotion could develop various of rollers used for different kinds of ERW tubes, cold roll-forming tubes and profiles, flattening rollers, support rollers, straightening rolls as well as sizing rollers.
