Cold Rolled Color Coated Steel Coil - Mill Direct Supplier
Cold rolled color coated steel coil represents one of the most versatile and aesthetically refined flat steel products available in today's construction and manufacturing markets. Produced by applying a polymer-based coating onto a cold rolled steel substrate, this material combines the dimensional precision of cold rolling with long-lasting surface protection and vibrant color retention. It finds extensive application in roofing panels, wall cladding, home appliances, automotive interior components, and commercial shelving systems. With a base metal thickness typically ranging from 0.12 mm to 1.5 mm and a total coated thickness that may reach up to 1.6 mm, these coils deliver consistent flatness tolerances within ±0.02 mm, ensuring seamless downstream processing. As a mill-direct supplier, we source material conforming to EN 10169, ASTM A755, and GB/T 12754 standards, guaranteeing traceable quality from melt to finished coil. Whether your project demands standard RAL colors or custom-matched shades, our cold rolled color coated steel coil portfolio covers the full spectrum of industrial and architectural requirements.
What is Cold Rolled Color Coated Steel Coil?
Cold rolled color coated steel coil is a flat-rolled steel product manufactured by continuously applying one or more layers of organic coating—such as polyester (PE), polyvinylidene fluoride (PVDF), or silicon-modified polyester (SMP)—onto a cold rolled, galvanized, or galvalume substrate. The result is a corrosion-resistant, color-stable material with a smooth surface finish that retains its mechanical properties, including a minimum yield strength of 250 MPa for structural grades, while offering superior decorative performance.
Cold Rolled Color Coated Steel Coil Manufacturing Process
Production begins with a premium-grade cold rolled or hot-dip galvanized coil substrate, which undergoes alkaline degreasing, chromate or chrome-free passivation, and primer application in a continuous coil coating line. A topcoat layer—commonly 15–25 µm for polyester or 25–35 µm for PVDF—is then applied and cured in a controlled thermal oven at temperatures between 200°C and 260°C. A protective backing coat of 5–10 µm is simultaneously applied to the reverse side, completing the sandwich structure before recoiling.
