Ensure product quality and transportation
Pre-painted steel sheets include both flat sheets and corrugated sheets, both manufactured from pre-painted steel coils through various processing methods. Their surfaces are coated with paint in different colors, offering features such as strong corrosion resistance, high strength, and excellent decorative properties.
Our pre-painted steel sheet colors are typically based on the RAL color chart. Please visit the RAL color chart. If you require custom colors, you may mail us your sample, and we will customize the color according to your sample.

What surface textures can we provide
- High-gloss surface: Features high surface gloss with rich, vibrant color.
- Matte surface: Low gloss level with minimal reflection.
- Frosted surface: Exhibits a uniform, fine-grained texture.
- Orange peel surface: Presents a subtle, uneven texture resembling orange peel.
- Embossed surface: Creates three-dimensional geometric patterns through mechanical embossing on the substrate.
- Printed Patterns: Surface designs include wood grain, stone texture, brick pattern, floral motifs, etc.
- Laminated Film-Coated sheets: A layer of polymer film (e.g., PVC, PET, or PETG) is laminated onto the surface to provide exceptional scratch resistance and chemical corrosion resistance.
Prepainted steel sheet coating structure type
1. Coating structure type
- 2/1: The upper surface is coated twice, the lower surface is coated once, and baked twice.
- 2/1M: Coat the upper and lower surfaces twice, and bake twice.
- 2/2: Coat the upper and lower surfaces twice, and bake twice.
2. Uses of different coating structures
- 2/1: The corrosion resistance and scratch resistance of the single-layer back paint are poor, but it has good adhesion and is mainly used in sandwich panels;
- 2/1M: The corrosion resistance, scratch resistance and processing formability of the back paint are good, and it has good adhesion, which is suitable for single-layer profiled panels and sandwich panels.
- 2/2: The corrosion resistance, scratch resistance and processing formability of the double-layer back paint are good, and most of them are used for single-layer profiled panels, but its adhesion is poor and it is not suitable for sandwich panels.
Application of Prepainted Steel Sheet
- Outdoor: factory buildings, agricultural warehouses, residential prefabricated components, corrugated roofs, walls, rainwater pipes, balconies, kiosks, rolling doors, etc.
- Indoor: doors, door frames, light steel structures of houses, screens, ceilings, elevators, stairs, ventilation ducts, etc.
- Electrical appliances: refrigerators, washing machines, switch cabinets, air conditioners, microwave ovens, bread machines, etc.
- Furniture: radiators, lampshades, wardrobes, tables, lockers, bookshelves, etc.
- Transportation industry: automobiles, train interior decoration, containers, fences, ship bulkheads, etc.
- Others: writing panels, garbage cans, billboards, clocks, typewriters, dashboards, weighing machines, photographic equipment, etc.

FAQ about Prepainted Steel Sheet
How to choose Prepainted Steel Sheets
- The first thing to consider when choosing prepainted steel sheets is where they will be used? Because the substrate, color, and coating required for different uses will be different.
- The second thing to consider is the use environment. Different use environments will have different service lives for prepainted steel sheets.
How to choose a supplier of Prepainted Steel Sheets
- Choose manufacturers that value product quality. It is difficult for low-priced manufacturers to meet product quality standards;
- Before purchasing, confirm the quality standards in advance. If conditions permit, you can go to the factory for on-site inspection.
What tests will Wanzhi prepainted steel sheets undergo before leaving the factory?
The pre-coated steel plates produced by Wanzhi Steel will undergo a variety of tests before leaving the factory: coating thickness test, corrosion resistance test, weather resistance test, flexibility test, physical property test (yield strength, tensile strength, elongation), zinc layer thickness test, etc.
