CR Steel Coil - Cold Rolled Steel Coil for Industrial Applications

CR steel coil represents a premium grade of cold-rolled carbon steel material that serves critical roles in automotive manufacturing, appliance production, and precision metal fabrication. Through a controlled cold reduction process at ambient temperature, this steel product achieves superior surface finish, tighter dimensional tolerances, and enhanced mechanical properties compared to hot-rolled alternatives. Our mill-direct CR steel coils deliver exceptional formability and consistent quality for manufacturers requiring reliable material performance in high-volume production environments.

What is CR Steel Coil?

Cold rolled steel coil is carbon steel that has undergone additional processing through cold reduction mills after initial hot rolling and pickling operations. This secondary processing at room temperature reduces thickness by 50-90% while simultaneously improving surface quality to Ra 0.5-1.5 μm and achieving thickness tolerances within ±0.05mm per ASTM A1008/A1008M standards.

CR Steel Coil Technical Specifications

Our cold rolled steel coils comply with ASTM A1008/A1008M-20 and EN 10130:2006 standards, available in commercial quality (CQ), drawing quality (DQ), and deep drawing quality (DDQ) grades. Standard thickness ranges from 0.15mm to 3.0mm with width options between 600mm and 1,524mm, supplied in coil weights up to 25 metric tons with inside diameter of 508mm or 610mm.

Why Choose Our Cold Rolled Steel Coils

We maintain strategic partnerships with certified mills holding ISO 9001:2015 and IATF 16949 accreditations, ensuring consistent material chemistry with carbon content controlled to 0.15% maximum for optimal welding characteristics. Our value-driven pricing structure reflects factory-competitive rates with flexible payment terms, while our technical support team provides material selection guidance and forming process optimization recommendations based on two decades of industry experience.

Frequently Asked Questions

What is the minimum order quantity (MOQ)?

Our standard minimum order quantity is 20 metric tons per specification. For trial orders or specialized grades such as high-strength low-alloy (HSLA) variants, we accommodate reduced quantities of 10 metric tons with adjusted pricing to support your project evaluation requirements.

Do you provide material test certificates?

Yes, we supply EN 10204 Type 3.1 mill test certificates with every shipment, documenting chemical composition analysis per ASTM E415 spectroscopic methods and mechanical properties including yield strength, tensile strength, and elongation values verified through standardized testing protocols.

What is the typical delivery time?

Standard grade CR steel coils ship within 15-20 business days from order confirmation for in-stock specifications. Custom thickness requirements or specific surface treatments such as skin-passed or temper-rolled finishes extend lead time to 25-30 business days depending on mill production schedules and current order volumes.

Can you cut to custom sizes?

Our processing facility offers precision slitting services to customer-specified widths with tolerance of ±1.0mm, along with cut-to-length operations for flat sheet production. We maintain slitting capabilities for widths as narrow as 20mm and can produce blanks up to 2,500mm length through our automated shearing lines equipped with hydraulic hold-downs for edge quality control.
