High Recyclability Pre Painted Steel Sheet With PVDF Coating For Enhanced Structural Integrity In 1500mm-5800mm Length

1. Product Overview

Pre painted steel sheet is used where a coated metal substrate and a finished color surface are both required in one material. This product is suitable for roofing sheets, wall cladding, façade panels, appliance panels, and general fabricated sheet parts where appearance, corrosion resistance, and processing 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 metallic or cold rolled 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, coating build affects surface durability, appearance retention, and handling performance during transport and installation.

The product is available with PE, SMP, HDP, and PVDF coatings. PE is commonly used for general purpose applications. SMP is typically selected where improved weather resistance is required. HDP is used where stronger durability is needed. PVDF is more suitable for exterior applications where UV resistance, chemical resistance, and long-term color retention are more important.

3. Specifications

4. Application

• This material is suitable for roofing sheets, wall cladding, façade panels, and other building envelope components.
• It can also be used for appliance panels, interior decorative panels, automotive related fabricated parts, transportation equipment panels, furniture parts, signage, and electrical enclosures.
• For projects that require both coated substrate protection and a finished visible surface, pre painted 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 final 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.
• Multiple base metal options allow selection by corrosion environment and fabrication requirement.
• Multiple coating systems allow the sheet to be matched to general purpose, weather resistant, or long-life exterior applications.
• RAL color customization supports project-based appearance matching.
• 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.
• 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 exterior applications requiring stronger UV and chemical resistance.
• Choose thickness according to panel rigidity, forming route, and installation span.
