Q235 Color Coated Steel Coil

Q235 color-coated steel coil is a versatile, high-performance steel product featuring a zinc-coated surface and a decorative color coating that enhances both durability and aesthetics. The “Q235” grade signifies a medium-carbon steel with a yield strength of approximately 235 MPa, offering good weldability, formability, and strength. The color coating, often made from polyester, PVC, or PVDF, provides superior resistance to corrosion, weathering, and UV damage. This type of steel coil is widely used in applications such as roofing, wall panels, home appliances, and automotive parts, offering a combination of excellent protection and attractive visual appeal for a variety of industrial and commercial uses.

Color Coated Steel Coil Standard Specification

The Q235 Color Coated Steel Coil is stored in our modern warehouse facility, designed to ensure optimal storage conditions. The warehouse is equipped with advanced climate control systems to regulate temperature and humidity, preventing rust and corrosion. Coils are carefully organized on specialized racking systems to maximize space efficiency and facilitate easy access for inventory management. Our warehouse maintains a large stock of Q235 Color Coated Steel Coil, ensuring prompt shipment and quick turnaround for bulk orders. Our organized, reliable warehouse ensures that customers receive their orders in perfect condition and on time, meeting your urgent delivery needs.

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.

Engineered to GB/T 12754 standards, Q235 Color Coated Steel Coil offers a thickness range of 0.3–2.0 mm (±0.02 mm tolerance), widths of 600–1,300 mm, and a durable polyester coating for indoor/light outdoor use. Available in 12+ standard RAL colors or custom-matched finishes, it delivers a tensile strength of 375–500 MPa and elongation up to 25% for simple forming in shelving, decorative panels, and light structural frameworks. Custom slit widths, coil weights (3–15 tons), and protective film options optimize production efficiency.

Our Q235 Color Coated Steel Coil is securely packaged in heavy-duty, edge-protected polypropylene sleeves with anti-scratch and moisture-resistant layers to preserve the pre-painted finish during global logistics. Each coil is shrink-wrapped with UV-blocking film and strapped with reinforced steel bands, ensuring color retention and corrosion resistance for cost-sensitive projects. Bulk orders (1,500+ coils) feature palletized packaging with customizable branding or eco-friendly recyclable materials to align with ESG initiatives. Request a free packaging sample to verify compliance with GB/T 12754 and ISO 9001 standards.
