Cold-Rolled Steel Coil (Matt Finish) - High-Quality China Suppliers and Factory for Deep-Drawn Components

Cold-rolled matte finish coils are expertly manufactured in our China factory using advanced work rolls with EDM-textured surfaces, achieving a precision finish with a Ra of 1.8–2.5 µm. This process creates a uniform, non-directional grain that significantly enhances the performance characteristics of the coils. With a matte surface boasting 60–85 GU gloss units, our coils improve paint adhesion by up to 40% compared to bright finishes. Additionally, our JIS G3141 SPCC/SPCE grades are batch annealed at 710°C, ensuring precise r-values between 1.4 and 1.8, making them ideal for deep-drawn components. As a trusted supplier in the industry, we provide high-quality products tailored to meet your specific needs

    Frequently Asked Questions

    What are the primary applications of matt finish cold-rolled steel coils?
    They are widely used in elevator interiors, server racks, and photovoltaic mounting systems where anti-reflective properties and high aesthetic consistency are required.
    How is the color consistency of these steel coils maintained?
    Color consistency is ensured through inline spectrometers that continuously monitor the L*a*b* color space, maintaining a strict tolerance of ΔE ≤1.0.
    What makes this steel coil suitable for complex forming geometries?
    The steel features n-values of 0.18–0.22, which provides excellent formability, allowing the material to be shaped into complex geometries without fracturing.
    Does the matt finish steel coil offer protection against corrosion?
    Yes, optional chromate passivation (15–30 mg/m² Cr) is available to enhance the corrosion resistance of the coils.
    Why are anti-reflective properties important for photovoltaic mounting systems?
    Anti-reflective properties minimize glare and light reflection, which helps optimize the performance and visual integration of photovoltaic installations.
