Product Description
Product Overview
Cold rolled steel is hot-rolled steel that has been cleaned of iron oxide scale (pickled) and reduced to specific thicknesses through precision rolling processes. The steel undergoes controlled temperature annealing to achieve required mechanical properties before final rolling to desired specifications.
This produces steel with precision dimensional tolerances and controlled surface finishes. Use cold-rolled steel where thickness tolerance, surface condition, and uniform mechanical properties are critical requirements.
ZhengDe Metal offers comprehensive cold rolled specialty alloys including high carbon, low carbon, and high strength low alloy (HSLA) precision tolerance strip steel.

Key Product Advantages
High Precision Manufacturing
Compared to hot-rolled steel plates, cold-rolled steel coils offer superior thickness precision, smooth surfaces, and excellent mechanical properties. The material undergoes annealing, pickling, and surface leveling to ensure optimal processing performance.
Extensive Applications
With smooth surfaces and excellent processing characteristics, these coils are ideal for automotive applications, household appliances (refrigerators, washing machines), industrial equipment, and building materials. Cold rolled hard coils serve as raw materials for hot dip galvanizing plants, with typical weights ranging from 8-23 tons.
Strict Production Process
Manufactured from hot-rolled strip steel (1.5-6mm thickness), the production includes pickling, cold rolling, degreasing, annealing, leveling, and shearing operations.
Deep Processing Capabilities
Our advanced slitting equipment processes cold rolled steel coils into various width strips, folded into small coils for downstream processing in transformer, motor, and precision metal industries.
Quality & Service Commitment
- Quality First: Strict production and inspection according to international standards
- Competitive Pricing: Market-based discounts and transparent pricing
- Transaction Security: Complete protection of customer funds
- After-Sales Support: Comprehensive problem resolution and customer service
- Long-Term Partnership: Consistent quality, competitive pricing, and dedicated service for sustainable cooperation
