Product Overview
We manufacture 2mm and 2.5mm thick cold-rolled steel coil with a standard width of 1250mm, achieving the optimal balance between strength, formability, and surface quality required for industrial manufacturing. Produced on advanced cold-rolling mills and subjected to rigorous quality control, these coils meet the requirements for dimensional accuracy and smooth surface finish in automotive sheet metal, home appliance housings, precision metalworking, and architectural components.
The room-temperature cold-rolling process refines the grain structure. Compared to hot-rolled products, these coils not only offer higher tensile strength (270–410 MPa) but also superior surface finish, making them ideal for applications requiring painting, coating, or galvanizing.

Manufacturing Process
Each coil of steel begins with high-quality hot-rolled base material, which then undergoes the following processes:
Pickling — Removes surface scale and oxides to produce a clean base material
Cold rolling — Reduces thickness at room temperature to meet strict tolerance requirements
Annealing — Restores ductility and eliminates internal stresses
Finishing — Improves flatness and surface finish
Final inspection — Laser thickness measurement, surface defect inspection, and mechanical property testing
This controlled process produces coils with thickness accuracy of ±0.01–0.02 mm and flatness below 5 I-units, ensuring consistent performance in high-speed stamping and roll forming production lines.
Why Choose Our Cold Rolled Coils?
FAQ
Q: What exactly does “2mm / 2.5mm × 1250mm” mean?
A: This is the most common thickness and width combination in our inventory. “2mm” and “2.5mm” refer to the coil thickness, while “1250mm” is the standard coil width. We can also slit 1250mm-wide coils into narrower strips (such as 600mm, 800mm, or 1000mm) to accommodate your processing equipment. If you require custom dimensions, please feel free to let us know your specific requirements.
Q: What steel grades are available for these dimensions?
A: For 2mm and 2.5mm thickness in 1250mm width, we typically stock SPCC, SPCD, SPCE, DC01, DC03, and DC04 grades. SPCC/DC01 is ideal for general forming and bending. If your application involves deep drawing or complex stamping (such as automotive panels or appliance housings), we recommend DC03 or DC04 for better elongation and formability.
Q: Can you supply coils in other thicknesses or widths?
A: Certainly. While 2mm and 2.5mm × 1250mm are our standard stock sizes, our production capabilities cover thicknesses ranging from 0.3mm to 3.0mm and widths from 600mm to 1500mm. Custom orders typically require a minimum order quantity of 25 metric tons per specification, with a lead time of 30–45 days.
Q: How do you ensure the quality of your cold-rolled steel coils?
A: Each coil of steel strip is manufactured in accordance with our ISO 9001:2015-certified production process and comes with a Mill Test Certificate (MTC) verifying its chemical composition, mechanical properties, and dimensional accuracy. We also conduct internal inspections, including tests for tensile strength, hardness, surface roughness, and flatness. At any stage, we welcome third-party inspections by SGS, BV, or an agency designated by you.
