Our standard MOQ for pre-painted steel coils is one 20-foot container. However, we understand the need for flexibility, especially for new partnerships. We are open to discussing smaller trial orders for initial cooperation. Please contact our sales team with your specific requirements.

Yes, we strongly encourage and provide sample testing. We offer free A4-sized samples of our standard white, green, and black surfaces. You only need to pay the freight cost. This allows you to verify the quality, writing performance, and magnetic strength firsthand.

Quality is embedded in our entire manufacturing process. We are certified under the ISO quality management system. Our quality control includes: Incoming raw material inspection. Real-time monitoring of coating thickness and uniformity on the production line. Final inspection for surface defects, flatness, and coating adhesion. We can provide Mill Test Certificates and are open to third-party inspections.

Single-coated surfaces have one layer of paint, offering a cost-effective solution for standard applications. Our double-coated surfaces feature a base coat and a top coat. This double-layer system provides superior durability, enhanced resistance to ghosting (staining), and a longer overall lifespan, making it ideal for high-traffic or premium applications.
