76mm 17mm Pre Painted Corrugated Roofing Sheet for Corrugated Metal Wall Panels

76mm 17mm Pre Painted Corrugated Roofing Sheet for Corrugated Metal Wall Panels

1．Product Overview

76mm 17mm pre painted corrugated roofing sheet is used for roofing sheets, corrugated metal wall panels, industrial roofing systems, construction cladding, container plates, and home appliance panels.

The product is manufactured from pre painted steel sheet and formed into corrugated profiles. The 76mm wave width and 17mm wave height improve panel rigidity, while the color coated surface supports building appearance and corrosion protection.

2．Technical Solution

The roofing sheet is processed from color coated steel with AZ30–150g/m² coating.

The paint system can include PVDF, HDP, SMP, PE, or PU top coating. Primer options include polyurethane, epoxy, and PE. Back coating options include epoxy and modified polyester.

Top paint thickness can be 15–35 microns, and back paint thickness can be 5–35 microns. Different coating systems can be selected according to roofing exposure, wall panel appearance, and project durability requirements.

3．Specifications

4．Application

This product is suitable for industrial corrugated roofing sheets, corrugated metal wall panels, roofing systems, wall cladding, warehouses, workshops, steel structure buildings, container plates, construction panels, home appliance panels, and general building envelope applications.

It is commonly used where color coated corrugated panels require long sheet length, multiple width options, and flexible coating selection.

5．Processing

The product supports color coating, corrugating, cutting, profiling, bundling, and standard export packing.

Customized thickness, width before corrugation, width after corrugation, length, coating type, paint thickness, RAL color, ditch and peak profile, and bundle weight can be supplied according to project requirements.

6．Advantages

• 76mm wave width and 17mm wave height improve roofing and wall panel rigidity.
• AZ30–150g/m² coating supports corrosion resistance for building applications.
• Top paint thickness of 15–35 microns supports surface appearance and weather protection.
• Back paint thickness of 5–35 microns supports backside protection and processing stability.
• PVDF, HDP, SMP, PE, and PU coating options support different project environments.
• Length range from 1000mm to 12000mm supports different roof spans and wall cladding layouts.

7．How to Choose

• Choose 0.12–0.30mm thickness for lightweight roofing and economical wall panels.
• Choose 0.30–0.60mm thickness when higher rigidity is required.
• Choose PVDF or HDP coating for stronger weather resistance.
• Choose PE or SMP coating for common roofing and wall cladding applications.
• Choose longer sheet length when reducing overlap joints is required.
• Choose the width after corrugation according to roofing layout and installation coverage.
• Confirm thickness, width, length, coating type, AZ coating, paint thickness, color, and corrugation profile before production.
