DX51D PVDF PPGI PPGL Steel Coil with 0.55mm Thickness and Z40 Coating for Roofing and Building Panels

１．Product Overview

DX51D PVDF PPGI PPGL Steel Coil is a pre-painted color coated steel coil used for roofing sheets, wall panels, steel structure workshops, warehouses, vehicle components, furniture panels, and electric industry applications.

The product uses galvanized steel coil or galvalume steel coil as the base material. With 0.55mm thickness, 1000mm width, Z40 zinc coating, and PVDF coating system, it supports outdoor building applications that require corrosion resistance, color stability, and forming performance.

２．Technical Solution

The base material is galvanized steel coil or galvalume steel coil. The metallic coating range can be Z40–Z275 or AZ40–AZ150 depending on the substrate and corrosion protection requirement.

The specified top surface uses 15μm polyester coating with 5μm primer, while the back surface uses 8μm coating with 5μm primer. This coating structure improves paint adhesion, surface protection, and reverse-side durability during forming, handling, and installation.

PVDF coating is suitable for applications requiring improved UV resistance, weatherability, and long-term exterior performance.
