Brief: Looking for a straightforward way to solve corrosion challenges in demanding applications? This video showcases the precision slitting process of Galvalume steel coils, demonstrating their superior resistance to harsh environments. You'll see how these coils are transformed into ready-to-use strips for construction, appliances, and solar projects, ensuring burr-free edges and optimal performance.
Related Product Features:
  • Features a 55% Al, 43.5% Zn, and 1.5% Si alloy coating for 2-6 times stronger corrosion resistance than standard galvanized steel.
  • Withstands temperatures up to 300°C, making it ideal for high-heat working conditions and applications.
  • Offers excellent formability with no coating peeling or cracking during bending, stamping, and shearing processes.
  • Provides a sleek silver-grey metallic finish that serves as a perfect base for color coating with superior adhesion.
  • Delivers precision slitting with ±0.1mm width tolerance, deburred edges, and flattening for smooth, straight strips.
  • Customizable in various spangles and RAL colors, with seaworthy packaging for safe international delivery.
  • Serves as a cost-effective alternative to aluminum and stainless steel, offering a longer service life.
  • Versatile for applications in building hardware, home appliances, auto parts, solar PV mounts, and warehouse racks.
FAQs:
  • What makes Galvalume steel coils more corrosion-resistant than galvanized steel?
    The unique 55% aluminum, 43.5% zinc, and 1.5% silicon alloy coating provides 2 to 6 times stronger corrosion resistance, especially in coastal or humid environments.
  • Can these slitted coils be customized for specific applications like solar mounts or appliances?
    Yes, the coils are tailor-made with precision slitting widths, specific coating weights, and mechanical properties to meet the requirements of solar PV mounts, home appliances, construction, and more.
  • How is the quality and precision ensured during the slitting process?
    Strict incoming inspection verifies thickness and coating, followed by precision slitting with ±0.1mm width tolerance, edge deburring, and flattening to ensure burr-free, straight strips ready for processing.
  • What packaging options are available for international shipping?
    We provide seaworthy packaging with moisture-proof paper, film wrapping, steel strapping, and wooden pallets to ensure safe delivery and prevent rust during transit.
