Cold-Rolled Steel Coil with Matt Finish - China Suppliers & Factory for High Adhesion and Deep-Drawing Applications

Our cold-rolled matt finish coils, manufactured in China, feature work rolls with EDM-textured surfaces (Ra 1.8–2.5 μm) that create a consistent, non-directional grain pattern. With a matte topography showcasing 60–85 GU gloss units, these coils improve paint adhesion by 40% compared to bright finishes. Our factory produces JIS G3141 SPCC/SPCE grades that undergo batch annealing at 710°C, ensuring precise r-values (1.4–1.that are perfect for deep-drawn components. As a trusted supplier, we prioritize quality and performance in our products.

    Frequently Asked Questions

    What are the primary applications for Matt Finish Cold-Rolled Steel?
    It is widely used in elevator interiors, server racks, and photovoltaic mounting systems where anti-reflective properties and a premium aesthetic are required.
    How is the color consistency maintained?
    We use inline spectrometers to monitor the L*a*b* color space, ensuring a strict color deviation of ΔE ≤1.0 for uniform appearance across batches.
    Is this steel suitable for complex forming?
    Yes, with n-values ranging from 0.18 to 0.22, the material offers excellent formability, allowing for complex geometries without the risk of fracturing.
    What corrosion protection options are available?
    We offer optional chromate passivation with a coating weight of 15–30 mg/m² Cr to enhance the material's resistance to environmental corrosion.
    Can I use this material for outdoor solar installations?
    Absolutely. Its anti-reflective properties and available corrosion resistance make it an ideal choice for photovoltaic mounting systems.
    What is the advantage of the "Matt Finish"?
    The matt finish reduces glare and reflections, provides a modern industrial look, and is better at hiding minor surface scratches compared to high-gloss finishes.
