1.0mm Ral1030 DX51D 1250mm Pre Painted Roofing Steel Sheet

1. Product Overview

Pre painted roofing steel sheet is used where a metallic coated steel substrate and a finished color surface are required in one material. This page is centered on a featured roofing specification of 1.0mm thickness and 1250mm width in RAL 1030 color, which is suitable for panel forming, roofing sheets, and exterior cladding applications.

The product is positioned for projects that need a painted surface, a controlled sheet size, and a substrate that can be processed into roofing profiles or flat architectural panels. Compared with post-painted sheet routes, pre painted steel sheet helps simplify downstream fabrication and keeps color consistency across the project.

2. Technical Solution

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

The listed metallic coating range is 40–275g/m2. The top side uses 15–20 micron polyester plus 5 micron primer. The back side uses 5–7 micron or 7–8 micron polyester plus 5 micron primer. This coating structure is suitable for roofing and cladding fabrication where outdoor exposure, transport handling, and roll forming all need to be considered together.

The page also lists commercial quality and lock forming quality. That matters during profiling because bend radius, profile depth, and forming stability depend on the base material condition as well as on the coating system.

4. Application

This material is suitable for roofing sheets, wall cladding, façade panels, and roof panels in residential, commercial, and light industrial buildings.

It can also be used for workshops, airports, storerooms, vehicle related exterior panels, furniture sheet parts, and electrical equipment housings where a finished painted surface is preferred over post-paint processing.

For roofing use, final service behavior also depends on profile design, overlap detailing, fastening practice, drainage condition, and the local exposure environment.

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 bends, lock forming quality is generally more suitable than standard commercial quality.
• When the finished surface is visible after installation, handling and storage should be controlled to reduce scratching on the painted face.

6. Advantages

• The featured 1.0mm thickness provides stronger panel rigidity than lighter gauge painted sheets.
• The 1250mm width is practical for roofing and cladding panel conversion.
• The 40–275g/m2 metallic coating range allows the product to be matched to different corrosion environments.
• The defined top and back coating structure supports controlled fabrication instead of relying on appearance alone.
• RAL color customization helps align the sheet with project appearance requirements.
• The product family also covers a wider thickness and width range for different panel layouts and forming routes.

7. How to Choose

• Choose 1.0mm when the project needs more panel rigidity and stronger handling stability.
• Choose a lower metallic coating level for lighter service conditions and a higher level within the listed 40–275g/m2 range when the environment is more demanding.
• Choose polyester for standard projects, SMP for improved weather exposure resistance, and PVDF when stronger UV resistance and longer finish retention are more important.
• Choose lock forming quality when the sheet will be used for deeper profiles or more demanding forming routes.
• Choose the final RAL color according to the project appearance target and the surrounding design scheme.
