cold-rolled coil
High-Precision Cold-Rolled Steel Coils (CRC) for Premium Manufacturing
Our factory delivers top-tier Cold-Rolled Coils (CRC) designed for applications requiring superior surface finish and tight dimensional tolerances. By processing high-quality hot-rolled pickled coils through advanced cold-reduction mills, we produce steel with enhanced strength, excellent workability, and a smooth, uniform surface. Compliant with international standards like ASTM A1008, EN 10130, and JIS G3141, our CRC is the ideal raw material for the automotive, home appliance, and precision engineering sectors. Whether you need full-hard or annealed coils, our cold-rolled steel provides the reliability and consistency your production line demands.

Industrial Cold-Rolled Steel Coils: Engineering Perfection with Superior Surface Quality
The Cold-Rolling Advantage
Cold-Rolled Coil (CRC) is steel that has been processed below its recrystallization temperature. Unlike hot-rolled steel, the cold-rolling process provides much greater control over the final product’s thickness, shape, and surface texture. Our factory utilizes state-of-the-art continuous tandem mills to ensure that every coil exhibits high tensile strength and a refined grain structure, making it indispensable for high-end manufacturing.
Technical Specifications & Grades
We offer a comprehensive selection of cold-rolled steel grades to meet various deep-drawing and structural requirements:
Commercial Steel (CS): Ideal for simple bending and forming (e.g., ASTM A1008 CS Type B, JIS G3141 SPCC).
Drawing Steel (DS): Formulated for moderate drawing applications (e.g., SPCD).
Deep Drawing Steel (DDS/EDDS): Optimized for complex shapes and automotive body panels (e.g., SPCE, SPCF).
Structural Steel (SS): Focused on high yield strength for load-bearing components.
Key Product Features
Exceptional Surface Finish: Our CRC features a clean, smooth surface (available in dull, bright, or matte finishes) that is perfect for subsequent painting, plating, or galvanizing.
Tight Thickness Tolerances: Advanced thickness-control systems ensure uniformity throughout the entire length of the coil, reducing material waste during stamping.
Enhanced Mechanical Properties: Cold reduction increases the hardness and strength of the steel, providing a better strength-to-weight ratio than hot-rolled alternatives.
Superior Flatness: Our leveling processes ensure the steel remains flat, preventing “oil canning” or warping during high-speed production.

Diverse Industrial Applications
Our Cold-Rolled Coils are the preferred substrate for numerous high-growth industries:
Automotive: Body panels, seat frames, and interior structural components.
Home Appliances: Exterior shells for refrigerators, washing machines, and microwave ovens.
Electrical Equipment: Switchgear cabinets, control boxes, and motor laminations.
Steel Furniture: High-quality filing cabinets, shelving systems, and desks.
Substrate for Coating: The primary material for Galvanized (GI) and Pre-painted (PPGI) steel production.
Quality Assurance & Logistics
As an ISO 9001 certified manufacturer, we implement rigorous testing for tensile strength, elongation, and Rockwell hardness. Every shipment is accompanied by a Mill Test Certificate (MTC) and is securely packaged with waterproof paper and steel strapping to prevent rust and edge damage during maritime transit.
