Product Specification

JIS RAL5078 1000mm ASTM A792 Color Coated Galvanized Steel Coil Pre Painted Sheet Metal

1. Product Overview

Pre painted steel coil is used where a metallic coated steel base and a finished color surface are 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 considered together.

This page is centered on a 1.2mm coil with 1250mm width and 5800mm cut length reference. The same product family also covers lighter gauges and narrower widths for different roofing and cladding routes.

2. Technical Solution

The product uses a metallic coated steel substrate with an organic paint system on the exposed side. In practical use, service behavior depends on the combined effect of metallic coating weight, paint film build, forming route, 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 standard roofing and cladding fabrication where roll forming, transport handling, and outdoor exposure all need to be considered together.

The page also refers to soft commercial quality and 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 1.2mm coil applications, it is more suitable where higher rigidity and stronger panel stability are needed compared with lighter gauge painted sheets.

5. Processing

• The coil 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 1.2mm 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 1250mm width is practical for standard panel conversion and profile design.
• CGLCC and DX52D 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 1.2mm when the project needs more panel rigidity and stronger handling stability.
• Choose the metallic 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.
