ST12-15 Color Coated Steel Coil

Product Description

ST12-15 color-coated steel coil is a high-quality cold-rolled steel product known for its excellent formability and smooth surface finish. The “ST12-15” grade indicates low-carbon steel with good mechanical properties, making it ideal for deep drawing and shaping applications. After the cold rolling process, the steel is coated with a protective color finish, typically made from polyester, PVC, or PVDF, to enhance corrosion resistance, UV protection, and weather durability. This versatile material is commonly used in manufacturing appliances, automotive parts, roofing, and wall panels, combining superior strength, flexibility, and aesthetic appeal for a variety of industrial and commercial uses.

Real-time inventory tracking allows us to fulfill orders promptly, ensuring that the ST12-15 Color Coated Steel Coil is always available when you need it, maintaining smooth operations for your production processes.

Product Inspection

The appearance of the coating is bright, meticulous, without sagging or wrinkles. Thickness inspection can use coating thickness gauge, the method is relatively simple. The thickness of the coating can also be obtained by converting the amount of zinc adhesion. For the bonding strength, a bending press can be used to bend the sample at 90-180°, and there should be no cracks or peeling of the coating. A heavy hammer can also be used to test, and the salt spray test and copper sulfate corrosion test can be done in batches.

Product Measurement

Engineered to ASTM A755 standards, ST12-15 Color Coated Steel Coil offers a thickness range of 0.3–1.5 mm (±0.03 mm tolerance), widths of 600–1,500 mm, and a pre-painted finish with PVDF or HDP coatings for superior weather resistance. Available in 20+ standard colors (RAL and custom-matched), it delivers a tensile strength of 300–450 MPa and elongation up to 18% for light forming applications. Custom slit widths, coil weights (3–15 tons), and protective film options optimize production for roofing, cladding, and furniture.

Product Packaging

Our ST12-15 Color Coated Steel Coil is securely packaged in moisture-resistant, edge-protected polypropylene sleeves to prevent scratches and corrosion during transit. Each coil is wrapped in anti-abrasion film and strapped with steel bands, ensuring the vibrant pre-painted finish remains intact for global logistics. Bulk orders (1,000+ coils) feature palletized packaging with customizable branding or eco-friendly recyclable materials to align with ESG goals. Request a free packaging sample to verify compliance with ASTM A755 and ISO 9001 standards.
