| High Light | Corrosion Resistant Color Coated Steel Coil ，UV Resistant Pre-painted Steel Coil ，High Durability Polyester Coating Painted Steel Coil | ||
Color Coated Steel Coil, also known as pre-painted steel coil, is a high-value flat steel product manufactured through a continuous roll-coating process. It involves applying multiple layers of liquid paints or coatings onto a metallic substrate (typically galvanized or galvalume steel), followed by precise baking and curing. This process creates a durable, colored, and protective film firmly bonded to the steel surface. The product combines the inherent strength and formability of steel with enhanced corrosion resistance, superior aesthetics, and long-term weatherability, serving as a ready-to-fabricate material for diverse industries.
| Parameter | Description / Typical Range |
|---|---|
| Base Metal Substrate | Cold-rolled (CR), Hot-dip Galvanized (GI), Galvalume (AZ), Aluminum-Zinc coated. |
| Coating System | Typically 2 coats (primer + topcoat) or 3 coats (primer + backer + topcoat). |
| Topcoat Type | Polyester (PE), Siliconized Polyester (SP), High Durability Polyester (HDP), Polyvinylidene Fluoride (PVDF), Plastisol. |
| Standard Thickness | 0.25 mm to 1.2 mm (coil substrate). |
| Standard Width | 600 mm to 1350 mm. Custom widths available. |
| Coil Weight | 3 to 15 Metric Tons (typical). |
| Coating Thickness | Topcoat: 15~25 μm per side. Total coating film: 20~200+ μm (varies by type). |
| Surface Finish | Glossy, Matte, Embossed, Textured, Wrinkle finish. |
| Color & Coil ID | Wide range of standard RAL/color codes. Reverse side can be coated (same/different color) or unpainted. |
| Key Performance | Corrosion resistance (salt spray test), Adhesion (T-bend test), Gloss/Color retention, Weathering resistance (QUV test). |
Primary Applications:
Building & Construction:
Roofing & Wall Cladding: For industrial warehouses, commercial buildings, agricultural facilities, and airports.
Garage Doors & Roller Shutters: Residential and industrial doors.
Composite Panels & Sandwich Panels: As the outer skin for insulated wall and roof systems.
Rainwater Systems: Gutters and downpipes.
Appliance & Home Electronics:
Major Appliances: Casings for refrigerators, washing machines, microwave ovens, and air conditioner housings.
Interior Components: Ceiling panels, kitchen hoods, and lighting fixtures.
Transportation & General Manufacturing:
Vehicle Interiors: Linings for trailers, caravans, and shipping containers.
Office & Home Furniture: Partitions, cabinets, and shelving systems.
Metal Ceilings, Partitions, and Signage Boards.
Key Advantages:
Superior Durability & Protection: The pre-applied coating forms a robust barrier against corrosion, UV radiation, and harsh weather, significantly extending the service life of the base metal.
Excellent Aesthetics & Design Flexibility: Available in a vast spectrum of colors, gloss levels, and textures, allowing for creative architectural and product design without the need for post-fabrication painting.
Cost & Time Efficiency: Eliminates the need for on-site painting, reducing labor costs, construction time, VOC emissions, and environmental hazards associated with traditional painting.
Ease of Fabrication: Maintains good formability (can be cut, punched, roll-formed, and bent) without significant damage to the coating, facilitating efficient manufacturing processes.
Hygienic & Low Maintenance: The smooth, non-porous surface is easy to clean and resists mold and dirt accumulation, reducing long-term maintenance costs.
Sustainable Choice: Often uses lead/chromate-free coatings, and the long product life contributes to resource conservation. Steel substrate is fully recyclable.
