Product Description
Product Overview
Zhengde Metal carbon steel coils are iron-carbon alloys with carbon content ranging from 0.0218% to 2.11%. These materials typically contain small amounts of silicon, manganese, sulfur, and phosphorus. Higher carbon content generally results in increased hardness and strength while reducing plasticity.

Key Product Advantages
High Precision Manufacturing
Compared to hot-rolled steel plates, our cold-rolled steel coils feature more precise thickness control, smooth surfaces, and superior mechanical properties, especially in processing performance. All coils undergo annealing, pickling, and surface leveling before delivery.
Extensive Applications
With smooth surfaces and excellent processing characteristics, these coils are ideal for automotive components, household appliances (refrigerators, washing machines), industrial equipment, and building materials. Cold rolled hard coils (8-23 ton weight range) serve as raw materials for hot dip galvanizing plants.
Strict Manufacturing Process
Our cold rolled steel coils use hot-rolled strip steel (1.5-6mm thickness) as raw material. The comprehensive production process includes: pickling, cold rolling, degreasing, annealing, leveling, and shearing operations.
Custom Processing Services
We provide slitting services to cut cold rolled steel coils into strips of various widths, then coil them for subsequent processing. This precision cutting capability is essential for transformer, motor, and other metal strip applications.
