China 0.8mm Thick 9012 White Ppgi Prepainted Steel Coils For Home Appliance
Pre-painted steel coils (PPSC) have become essential materials in home appliance manufacturing
due to their excellent corrosion resistance, diverse color options, and environmental benefits.
Prepainted steel sheet can be used in advanced forming operations such as roll forming, bending
and deep drawing. It can be worked by cutting, roll forming, bending, folding and so on.
Key Properties of Pre-Painted Steel Coils
♦ Aesthetic Appeal
Available in a wide range of colors, gloss levels (matte, glossy), and patterns (wood grain, stone effect).
Uniform surface finish eliminates the need for additional painting.
♦ Corrosion Resistance
Base metal: Galvanized (GI) or galvalume (GL) steel for enhanced rust protection.
Organic coatings (polyester, silicone-modified polyester, PVDF) provide an extra barrier against moisture
and chemicals.
Salt spray resistance (typically 500+ hours), ideal for humid environments (e.g., refrigerators, washing
machines).
♦ Formability & Durability
Excellent adhesion and flexibility for stamping, bending, and deep drawing.
Scratch-resistant surface reduces damage during fabrication and assembly.
♦ Eco-Friendliness
VOC-free (compared to post-painting) and compliant with RoHS/REACH standards.
Some coatings are recyclable.
♦ Cost Efficiency
Eliminates secondary painting processes, reducing production time and costs.
Advantages for Home Appliance Manufacturing
Replacement for Traditional Materials
vs. Stainless Steel: Lower cost, lighter weight, and more color options.
vs. Post-Painted Steel: Avoids paint peeling and ensures consistent quality.
Lightweight Design
Thinner gauges (0.4–1.0 mm) reduce weight without compromising strength.
Typical Thicknesses for Home Appliances
| Appliance Type | Thickness (mm) | Base Material |
| Refrigerator/Washing Machine | 0.5–0.8 | GI or GL |
| Air Conditioner Outdoor Unit | 0.6–1.0 | GL (better heat resistance) |
| Microwave/Oven Inner Liner | 0.4–0.6 | GL (high-temperature use) |
| Small Appliance Panels | 0.3–0.5 | GI |
Pre-painted steel coils are revolutionizing appliance manufacturing by combining durability,
design versatility, and sustainability to replace stainless steel, plastics, and glass in premium applications.
