JIS G3312 RAL5017 PPGL Pre Painted Steel Sheet 3000mm

JIS G3312 RAL5017 PPGL Pre Painted Steel Sheet 3000mm

1. Product Overview

PPGL pre painted steel sheet is used where a metallic coated steel substrate 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 building sheets where appearance, corrosion resistance, and forming compatibility need to be considered together.

This page is centered on a featured sheet size of 1.25mm thickness, 1250mm width, and 3000mm length. The listed grade route includes CGLCC and DX52D, which is suitable for coated sheet processing where panel rigidity and visible surface quality are both important.

2. Technical Solution

The product uses a metallic coated steel substrate with an organic paint system on the exposed surface. In practical use, service behavior depends on the combined effect of metallic coating level, paint film build, forming route, panel design, and installation environment.

The listed paint structure uses 15–25 micron top coating and 5–7 micron back coating. This coating build is suitable for roofing and cladding fabrication where roll forming, transport handling, and outdoor exposure all need to be considered together.

The product is also described as soft commercial quality or lock forming quality. That matters in actual processing because bend radius, profile depth, and forming stability depend on the base material condition as well as on the paint system.

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 corrugated panels, decorative exterior sheets, ceiling panels, and fabricated sheet parts where a pre-finished visible surface helps reduce downstream painting work.
• For 1.25mm sheet applications, it is more suitable where additional rigidity is needed compared with lighter gauge painted sheets.

5. Processing

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

6. Advantages

• The 1.25mm sheet thickness provides higher rigidity for roofing and wall panel applications.
• The 1250mm width is practical for standard panel conversion and profile design.
• The defined top and back coating structure provides a controlled painted surface for exterior panel use.
• CGLCC and DX52D are practical grade options for coated construction sheet processing.
• Multiple surface finishes and RAL color customization support both functional and decorative applications.

7. How to Choose

• Choose 1.25mm when the project needs more panel rigidity and stronger handling stability.
• Choose the final width according to panel layout, effective coverage, and roll forming line requirement.
• Choose soft commercial quality for standard forming routes and lock forming quality for more demanding profiles.
• Choose matt, gloss, wrinkle, wood grain, or marble surface according to the final design requirement.
• Choose the final RAL color according to the project appearance target and surrounding design scheme.
