Aluzinc 0.56mm Pre Painted Steel Sheet Metal Roofing Gl PPGL Sheet For Houses

Aluzinc 0.56mm Pre Painted Steel Sheet Metal Roofing Gl PPGL Sheet For Houses

1. Product Overview

Pre painted aluzinc steel sheet is used where a corrosion resistant metallic coating and a finished color surface are both required in one material. This product is positioned for house roofing sheets and light building panels where appearance, weather exposure, and downstream forming all matter.

The featured page size is 0.56mm thickness and 1000mm width, which is a practical configuration for roofing sheet production. The aluzinc base and painted surface help separate this product from plain galvanized sheet in applications where longer exterior service and more stable finish are required.

2. Technical Solution

This product uses an aluzinc coated steel base with an organic paint system on the exposed surface. In practical use, performance depends on the combined effect of metallic coating weight, paint build, forming route, and installation environment.

The top side uses 10 micron polyester plus 5 micron primer. The back side uses 5–7 micron back coating. This coating structure is suitable for standard roofing and cladding fabrication where roll forming, transport handling, and outdoor exposure all need to be considered.

The product can also be supplied as GI, GL, PPGI, PPGL plain sheet, or corrugated steel sheet within the listed product family.

3. Specifications

4. Application

• This material is suitable for house roofing sheets, corrugated roof panels, wall cladding, and light steel structure buildings.
• It can also be used for industrial and civil construction, workshop roofs, airport and storeroom panels, furniture related sheet parts, and electrical industry applications.
• For residential roofing, it is more suitable where the project needs colored exterior finish together with aluzinc based corrosion resistance.

5. Processing

• The sheet can be supplied in coil or converted into plain sheet and corrugated sheet according to downstream requirement.
• It is suitable for roll forming, profiling, cut to length processing, bending, and general sheet fabrication.
• For roofing sheet production, thickness, paint system, and hardness should be selected together to match forming radius, panel profile depth, and transport handling conditions.

6. Advantages

• The 0.56mm and 1000mm configuration is practical for roofing sheet conversion.
• The aluzinc base improves corrosion resistance compared with uncoated steel.
• The polyester top coating provides a finished colored surface for direct installation.
• The available coating range of 40–275g/m2 supports different project requirements.
• The wider product range of 0.18mm–1.20mm and 700mm–1250mm helps match different roofing and cladding lines.

7. How to Choose

• Choose 0.56mm when the project needs a balance between roof panel rigidity and forming efficiency.
• Choose 1000mm width when the downstream line is configured for that sheet layout or roofing profile yield.
• Choose higher metallic coating levels when the service environment is more demanding.
• Choose soft or full hard condition according to the required forming route and panel profile.
• Choose the final color according to project appearance requirement and roof temperature considerations.
