JIS G3312 1.0mm Pre Painted Galvanized Steel Sheet CGCC DX51D

1. Product Overview

Pre-painted galvanized steel sheet is used where a zinc-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 performance need to be balanced.

This page is centered on a 1.0mm sheet with 3000mm length under JIS G3312, while the same product family also covers 0.2–1.0mm thickness and 700–1250mm width. CGCC and DX51D are practical grade options for standard construction sheet processing.

2. Technical Solution

The product uses a galvanized steel base combined with an organic paint system. In practical use, service behavior depends on three linked factors: zinc coating weight, 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 roll forming, transport handling, and outdoor exposure all need to be considered together.

The product is also available in soft commercial quality or lock forming quality. That matters in actual processing because bend radius, profile depth, and forming stability depend on base material quality as well as 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 1.0mm 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 1.0mm sheet thickness provides higher rigidity for roofing and wall panel applications.
• 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.
• 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.
• Multiple surface finishes and RAL color customization support both functional and decorative applications.

7. How to Choose

• Choose 1.0mm when the project needs more panel rigidity and stronger handling stability.
• Choose the zinc coating level according to the service environment and expected corrosion demand.
• 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 color according to the project appearance target and surrounding design scheme.
