WebbCold rolling can make the steel produce large plastic deformation, thus improving the yield point of the steel. Cold rolling can be made into a variety of cross-section forms to meet the requirements of use conditions. Short manufacturing time and prompt delivery. Excellent strength/weight ratio. Webb25 juni 2024 · Cold rolling is a round bar that is rolled into regular sections on a cold rolling mill to improve its strength and adhesion to concrete. When the steel bar is rolled in cold rolling, it deforms both lengthwise and crosswalk at the same time, so its plasticity and internal structure uniformity can be well maintained.

WebbDuring the cold roll forming, operations such as punching, stamping, can be done online. Then, the metal section is cut at the end of the line to the desired length.
