Pre-painted Steel Coil
Aesthetics Meets Durability:
The Premium Choice for Exterior Cladding & Sandwich Panels
Our Pre-painted Steel Coil (PPGI) combines the strength of steel with the corrosion resistance of zinc and the beauty of organic paint. Using hot-dip galvanized steel coil as the substrate, we apply advanced coating technologies to deliver a product that offers superior weather resistance and vibrant aesthetics. It is the ideal raw material for the outer layers of high-quality EPS/PU sandwich panels and architectural roofing projects.
Key Features
We offer a fully tailored solution to meet your specific architectural and manufacturing needs:
-
Unlimited Colour Customisation: We support any colors based on the RAL color standard or your customer’s specific samples. Whether you need standard white-grey for industrial warehouses or vibrant colors for commercial buildings, we ensure excellent color retention and consistency.
-
Customised Coating System: Durability is key. The Zinc coating and paint thickness are adjustable as requested. We can customize the coating structure (Primer + Top Coat + Back Coat) and paint type (PE, SMP, HDP, PVDF) to suit different environmental conditions, from standard inland areas to harsh coastal climates.
-
Precision Manufacturing: We provide thickness and width as requested, ensuring seamless integration with your roll forming machines or sandwich panel lines. Our strict quality control guarantees accurate size and a perfect surface, free from bubbles, scratches, or peeling.
-
Flexible Processing: To optimise your production efficiency, any length can be cut (for sheets), or coil weights can be adjusted to match your uncoiler’s capacity.
-
Secure Export Packaging: We utilise fine packaging suitable for export, featuring vertical or horizontal packing with waterproof kraft paper, galvanised metal sheets, and steel bands to ensure the coils arrive without moisture damage or edge deformation.
