0.48mm RAL 7065 Prepainted Galvanized Steel Coil for Roofing and Container Panel Applications

１．Product Overview

0.48mm Prepainted Galvanized Steel Coil is designed for roofing systems, steel structure buildings, container panels, and industrial fabrication projects. Manufactured using a galvanized steel substrate and polyester coating system, the product combines corrosion protection, decorative appearance, and forming performance.

The RAL 7065 finish provides a modern industrial grey appearance commonly specified for commercial buildings, warehouses, container structures, and engineering projects.

２．Technical Solution

The steel substrate is protected by a 60g/m² zinc coating that provides sacrificial corrosion protection. A coil coating system consisting of 15 Micron Polyester + 5 Micron Primer on the exposed surface and 7 Micron + 5 Micron Primer on the reverse side improves adhesion, weather resistance, and coating durability.

The continuous coating process ensures consistent color, coating thickness, and surface quality suitable for roll-forming and fabrication operations.
