700–1250mm Pre Painted PVDF Steel Coil with 30–275g/m² Zinc Coating for Industrial Roofing and Wall Cladding

１．Product Overview

Pre Painted Steel Coil is a color coated steel material used for industrial roofing, wall cladding, exterior panels, manufacturing components, and building envelope systems.

This product uses zinc coated steel as the substrate and applies PE, SMP, HDP, or PVDF paint coating to improve surface durability, corrosion resistance, and color appearance. With 700–1250mm width, 3–8MT coil weight, and 508 / 610mm coil ID, it is suitable for continuous roll forming, profiling, slitting, and panel fabrication.

２．Technical Solution

The product is produced through pre-painted coil coating technology. Zinc coating from 30–275g/m² provides corrosion protection for the steel substrate, while the paint coating improves weather resistance, UV resistance, and surface stability.

The 10–25μm top coating provides exposed-side protection and appearance control. The 5–7μm back coating improves reverse-side protection during transportation, storage, forming, and installation.

PVDF coating is suitable for industrial and outdoor applications requiring stronger weather resistance. PE, SMP, and HDP coatings can also be selected according to different application environments and durability requirements.
