Key Advantages for Your Business
- Durable Coating Performance: PE coating offers excellent gloss and color stability for interior applications; HDP coating provides enhanced UV resistance and chalk resistance for exterior use, extending product lifespan.
- Precise Thickness Control: Our advanced production lines ensure thickness tolerance within ±0.02mm, reducing material waste during forming.
- Excellent Formability: The galvanized substrate provides good ductility, allowing easy bending, stamping, and profiling without cracking or peeling.
- Consistent Color: Computer-controlled color mixing and application ensure uniform color across batches, meeting aesthetic requirements for large-scale projects.
- Customization Flexibility: We offer custom width, thickness, color, and coating weight to match your specific project needs, with minimum order quantity as low as 50 tons.
- Cost-Effective Solution: Compared to post-painting processes, our pre-coated coils save labor, energy, and time, reducing overall production costs for downstream manufacturers.

Frequently Asked Questions
-
Q: What is the difference between PE and HDP coating?
A: PE (Polyester) coating offers good gloss and color retention for indoor applications, while HDP (High Durability Polyester) provides superior UV resistance and chalk resistance, making it ideal for outdoor exposure. Both comply with JIS G3312. -
Q: Can I get custom colors or RAL matching?
A: Yes, we offer a wide range of RAL colors and can match custom color samples. Please provide your color code or sample during order inquiry. -
Q: What is the minimum order quantity (MOQ)?
A: Our MOQ is typically 50 tons per specification, but we can negotiate smaller quantities for trial orders. Contact our sales team for details. -
Q: How do you ensure coating adhesion and no peeling?
A: We use advanced pre-treatment (degreasing, chemical conversion) and strict cure oven control. Each batch undergoes cross-cut tape test and bending test to ensure adhesion meets JIS G3312 requirements. -
Q: What is the typical lead time?
A: For standard specifications, lead time is 15-20 days after receipt of deposit. Custom orders may require 25-30 days depending on complexity. -
Q: Do you provide samples before bulk order?
A: Yes, we can provide free samples (A4 size) for quality evaluation. The buyer is responsible for shipping costs. Samples are usually dispatched within 3-5 working days. -
Q: Is the coil suitable for direct exposure to coastal environments?
A: For coastal areas, we recommend HDP coating with higher zinc coating weight (≥120 g/m²) for enhanced corrosion resistance. Please consult our technical team for specific recommendations. -
Q: What packaging do you use for export?
A: Our coils are packed with anti-rust paper, plastic film, steel strapping, and edge protectors. For sea freight, we add waterproof wrapping and wooden pallets as standard.
