17mm Pre Painted Corrugated Roofing Sheet 20mic Zinc Coated Sheet Metal

17mm Pre Painted Corrugated Roofing Sheet 20mic Zinc Coated Sheet Metal

1．Product Overview

17mm pre painted corrugated roofing sheet is used for construction roofing, wall cladding, workshops, agricultural warehouses, residential precast units, electrical appliance panels, furniture panels, container decoration, and general building material applications.

The product is manufactured from zinc coated or aluminum-zinc coated steel sheet with color coated surface. The 76mm wave width and 17mm wave height improve panel rigidity, while the top paint layer and primer support surface protection and color appearance for roofing and cladding use.

2．Technical Solution

The roofing sheet is produced from PPGI corrugated sheet according to JIS, ASTM, GB, and BS standards.

Zinc coating options include Z20–Z275 and AZ30–AZ150. Painting thickness includes top side 10–20 microns, primer 5–7 microns, and back side 5–7 microns.

Surface coating options include PE, PVDF, SMP, and HDP. These coating systems can be selected according to project exposure, corrosion resistance requirement, surface appearance, and building design.
