CRC Polished Cold Rolled Mild Carbon Steel Strip Coil 1.5-6mm Thickness for Automotive & Industrial Applications
Zhengde CRC polished cold rolled mild carbon steel strip coil is manufactured using hot-rolled steel coil as raw material, processed through acid washing to remove oxide scale and cold continuous rolling. The resulting hard coil exhibits increased strength and hardness due to cold work hardening, with excellent surface quality and dimensional precision.

Superior dimensional accuracy with smooth, beautiful surfaces and excellent mechanical properties, particularly in processing performance. Typically requires annealing, pickling, and surface leveling before delivery.
Widely used in automotive, home appliances (refrigerators, washing machines), industrial equipment, and construction materials. Rolled hard coils (8-23 ton weight range) serve as raw materials for hot dip galvanizing plants.
Utilizes 1.5-6mm hot-rolled strip steel as billet, processed through pickling, cold rolling, degreasing, annealing, leveling, and shearing operations.
Professional slitting equipment cuts coils into various width strips for transformers, motor industries, and precision metal applications.
