1. Product Overview

PPGI pre painted steel sheet is used where a galvanized steel base and a finished color surface are both required in one material. This product is suitable for roofing sheets, wall cladding, façade panels, and general fabricated sheet parts where appearance, corrosion resistance, and roll forming compatibility need to be considered together.

This page is centered on 0.8mm thickness and 3000mm sheet length, with width range from 700mm to 1250mm. The specified grade route includes CGCC and DX51D, which are commonly used for painted construction sheet processing.

2. Technical Solution

The product uses a metallic coated steel substrate with an organic paint system on the exposed surface. In practical use, performance depends on three linked factors: zinc coating level, paint film build, and forming route.

The metallic coating range is Z40–150g/m². The paint system uses 15–25 micron top coating and 5–7 micron back coating. This structure is suitable for standard roofing and cladding fabrication where forming, transport handling, and outdoor exposure all need to be considered.

The product is available in soft commercial quality and lock forming quality. That matters in actual processing because sheet profile depth, bend radius, and roll forming stability are affected by base grade and forming quality rather than color alone.

3. Specifications

4. Application

• This material is suitable for roofing sheets, wall panels, and façade cladding in residential, commercial, and light industrial buildings.
• It can also be used for interior partition panels, decorative sheet parts, appliance related panels, and other fabricated components where a pre finished surface helps reduce downstream painting work.
• For RAL6019 or other light colors, it is suitable where visual consistency and clean panel appearance are important in the finished project.

5. Processing

• The sheet can be supplied for direct use in cut length form or for downstream profiling and forming.
• It is suitable for roll forming, bending, shearing, and general sheet metal fabrication.
• For deeper profiles or tighter bend radius, lock forming quality is usually more suitable than general commercial quality.
• Surface handling should be controlled during storage, cutting, and installation to reduce paint film scratching on visible faces.

6. Advantages

• The 0.8mm thickness is suitable for many roofing and wall panel applications that need a balance between rigidity and forming efficiency.
• The Z40–150g/m² metallic coating range supports different corrosion protection targets.
• The 15–25 micron top coating provides a defined painted surface for exterior panel use rather than a post paint route.
• The 700–1250mm width range matches mainstream roofing and cladding sheet processing lines.
• CGCC and DX51D are practical grade options for painted construction sheet processing.

7. How to Choose

• Choose 0.8mm when the project needs a practical balance between panel rigidity and processing efficiency.
• Choose the zinc coating level according to project environment and expected service condition.
• Choose lock forming quality when the sheet will be used for deeper profiles or more demanding forming routes.
• Choose matt, gloss, wrinkle, wood grain, or marble surface according to the final design requirement.
• Choose RAL6019 or other customized RAL color according to the project appearance target and surrounding design scheme.
