What is Roofing Sheet ?

Roofing Sheet is a type of steel product with a surface coated in organic pigments or polymer films, providing both decorative and protective properties. The coating is applied through a continuous rolling process, combining corrosion resistance with customizable colors and textures. Unlike bare steel, color coated sheets are widely used in architectural, automotive, and consumer industries where aesthetic appeal and durability are essential.

Manufacturing Process of Roofing Sheet

1. Roll Coating Process::The cleaned sheet passes through a chemical bath to form a conversion coating (e.g., chromate or zirconium) for corrosion resistance.A primer layer (1–5 μm) is applied via roller to improve adhesion and prevent rust. Common primer types include epoxy or polyester.The main color layer (10–25 μm) is applied using precision rollers. Pigments can be customized for color, gloss, or texture (e.g., matte, metallic, embossed). A protective layer is applied to the reverse side of the sheet to prevent corrosion from the underside.
2. Curing:The coated sheet is heated in an oven (180–250°C) to cure the paint, forming a durable, cross-linked polymer film.
3. Post-Processing: Some sheets may be laminated with plastic films or protective layers for added scratch resistance (e.g., in appliance manufacturing).The large coils are cut into specified sizes for different applications (e.g., roofing panels, door skins).

Advantages of Roofing Sheet

1. Aesthetic Versatility:Customizable colors, patterns, and finishes (e.g., wood grain, stone texture) allow design flexibility for architectural facades, interior decor, or consumer products.Consistent color uniformity across large surfaces reduces painting on-site, saving time and costs.
2. Устойчивость к коррозии:The organic coating acts as a barrier against moisture, chemicals, and UV radiation, while the galvanized steel substrate (if used) provides additional rust protection.Suitable for outdoor applications like roofing, siding, or signage in coastal or industrial environments.
3. Эффективность затрат:Pre-painted sheets eliminate the need for on-site painting, reducing labor and equipment costs.Long-lasting coatings minimize maintenance (e.g., repainting) and extend product lifespan compared to bare steel.
4. Formability and Lightweight:The coating remains intact during bending, rolling, or stamping, making it ideal for complex shapes in automotive bodies, appliance casings, or HVAC ducts.Lighter than alternative materials (e.g., aluminum) while maintaining structural strength.
5. Environmental Benefits:Low-VOC (volatile organic compound) coatings are increasingly used, aligning with green building standards.Recyclable steel substrate reduces environmental impact, and some coatings are designed for easy separation during recycling.
