Brief: Learn how this solution can streamline typical workflows and improve reliability. In this video, we showcase our custom-color prepainted galvanized steel coils, demonstrating how they are engineered to meet your exact project specifications. You'll see the full customization process for color and dimensions, the dual protection of galvanized substrate and high-adhesion coatings, and the quality assurance measures that ensure long-term performance in construction and industrial applications.
Related Product Features:
  • Full customization of color from over 200 RAL and Pantone shades with precise color matching accuracy (ΔE ≤ 1.0).
  • Wide range of specification options including substrate thickness from 0.12mm to 2.0mm and coil width from 600mm to 1500mm.
  • Choice of coating types such as polyester (PE), silicon-modified polyester (SMP), high-durability polyester (HDP), and PVDF fluorocarbon for varying climate resistance.
  • Galvanized substrate provides excellent corrosion resistance, ductility, and formability for bending and stamping without coating damage.
  • Premium coatings offer strong adhesion (grade 0), weather resistance, and environmental compliance with RoHS standards.
  • ISO 9001:2015 certified production with full inspection of thickness, zinc layer weight, and coating adhesion for consistent quality.
  • Third-party testing reports available for salt spray resistance (up to 2000 hours), impact resistance, and color fastness.
  • Factory-direct pricing, fast lead times of 7-15 days, and free samples for quality confirmation before bulk orders.
FAQs:
  • What customization options are available for the prepainted galvanized steel coils?
    We offer full customization including color from over 200 RAL and Pantone shades or client-specified colors with precise matching, substrate thickness from 0.12mm to 2.0mm, coil width from 600mm to 1500mm, galvanizing coating weight from 40g/m² to 275g/m², and surface finishes like matte, glossy, embossed, or striped textures.
  • How does the dual protection of galvanized substrate and coating enhance durability?
    The hot-dip galvanized substrate forms a dense zinc-iron alloy barrier for rust and corrosion resistance, while the high-adhesion coatings (e.g., PE, PVDF) provide weather resistance, with PVDF offering up to 15+ years of anti-fading, ensuring long-term performance in harsh environments.
  • What quality assurance and certifications do you provide?
    Our production is ISO 9001:2015 certified, with full inspection of each coil's specifications. We also offer third-party test reports from SGS, BV, or Intertek for salt spray resistance (up to 2000 hours), impact resistance, and color fastness, ensuring traceability and consistent quality.
  • What is the lead time and sample availability for custom orders?
    Standard color orders have a lead time of 7-10 days, while custom color and special specification orders take 12-15 days. We provide free 20cm×20cm samples for color and quality confirmation before bulk ordering.
