15-20 Micron Polyester +5 Micron Primer Pre-Coated Steel Sheet With 700mm-1250mm Width And High Recyclability For Roofing And Cladding

15-20 Micron Polyester +5 Micron Primer Pre-Coated Steel Sheet With 700mm-1250mm Width And High Recyclability For Roofing And Cladding

1. Product Overview

Pre coated steel sheet is used where a coated steel substrate and a finished color surface are required in one material. It is suitable for roofing sheets, wall cladding, façade panels, appliance panels, and general fabricated sheet parts where appearance, corrosion resistance, and forming compatibility need to be considered together.

The available size range covers 0.18–1.2mm thickness, 700–1250mm width, and 1500–5800mm length. Base metal options include galvanized steel, galvalume steel, and cold rolled steel, which allows the sheet to be selected according to service environment and fabrication route.

2. Technical Solution

The product uses a painted coating system built on steel substrate. The top side uses 15–20 micron polyester with 5 micron primer. The back side uses 5–7 micron, or 7–8 micron polyester with 5 micron primer. In actual use, surface durability depends on the combination of substrate type, primer support, top coat build, and handling during fabrication and installation.

The available coating systems are PE, SMP, HDP, and PVDF. PE is generally selected for standard applications. SMP is used where better weather resistance is required. HDP is suitable where stronger durability is needed. PVDF is more suitable for applications requiring stronger UV resistance, chemical stability, and long-term color retention.

4. Application

• This material is suitable for roofing sheets, wall cladding, façade panels, and other building envelope parts.
• It can also be used for appliance panels, automotive related fabricated parts, decorative panels, furniture parts, signage, and general industrial sheet components.
• For projects that require a finished visible surface and a coated base metal in one material, pre coated steel sheet is a practical option for direct fabrication.

5. Processing

• The sheet can be supplied in cut length for direct fabrication.
• It is suitable for cutting, bending, roll forming, profiling, and general sheet metal processing.
• When the final part has visible surface requirements, protective film on the top side can be selected to reduce handling damage during transport and installation.
• Base metal and coating type should be selected together according to forming severity, outdoor exposure, and the required service condition.

6. Advantages

• The 0.18–1.2mm thickness range is suitable for light to medium sheet fabrication.
• The 700–1250mm width range matches common panel and cladding processing routes.
• The 1500–5800mm length range supports both shorter fabricated parts and larger panel layouts.
• Multiple base metal options allow selection by corrosion environment and fabrication requirement.
• Multiple coating systems allow the sheet to be matched to standard use, weather resistant use, or longer-life exterior applications.
• High recyclability supports projects where material recovery and sustainability are important considerations.

7. How to Choose

• Choose galvanized steel base for general painted sheet applications where zinc-coated substrate is required.
• Choose galvalume steel base when the project requires aluminum-zinc coated substrate and improved corrosion resistance.
• Choose cold rolled steel base when the application is more focused on interior or protected-use fabrication.
• Choose PE for standard use, SMP for stronger weather exposure, HDP for higher durability demand, and PVDF for applications requiring stronger UV and chemical resistance.
• Choose thickness according to panel rigidity, forming route, and installation span.
• Choose length according to blank layout, transport condition, and installation size.
