Cold Rolled Coils and Sheets


High-grade precision cold rolled sheet (coil) takes hot rolled steel coil as raw material and undergoes multi-pass precision cold rolling at room temperature to greatly reduce plate thickness, effectively improve surface flatness and finish, with extremely tight thickness tolerance and uniform and stable metallographic structure. As the core base substrate for various precision stamping parts and sheet metal parts, coils can be cut to length or slit according to customer orders to meet high-precision forming requirements of home appliance, electronics and automotive interior industries.

Main Features

  1. Bright & fine surface with few defects and high flatness;
  1. High thickness accuracy with controllable tolerance, ideal for precision forming and deep drawing;
  1. Excellent plate plasticity with stable deep drawing and bending performance and low cracking risk;
  1. Clean substrate surface, convenient for subsequent surface treatments including galvanizing, prepainting and spraying.
