FAQs

Can you support small trial orders before bulk cooperation?
Yes. We support trial orders starting from 1 metric ton, allowing customers to verify quality and processing compatibility before placing large-volume contracts.

Can coils be supplied with specific coating weight or paint thickness?
Yes. For galvanized and color-coated coils, coating weight (e.g., Z40–Z275, AZ coating) and paint thickness can be produced according to project requirements. Technical specifications can be confirmed before production.

How do you ensure batch-to-batch consistency?
All coils are produced under standardized production control and strict inspection procedures. Each batch is traceable and supplied with Mill Test Certificates (EN 10204 3.1), ensuring stable quality for long-term cooperation.

Can you optimize container loading to reduce freight costs?
Yes. We provide professional container loading plans based on coil weight and size to maximize loading efficiency and minimize shipping costs.

What is your typical production and delivery timeline?
Stock materials can be shipped within 3–7 days. For made-to-order coils, delivery time depends on specifications and quantity, typically 10–45 days.

Which industries commonly use your steel coils?
Our coils are widely used in pipe manufacturing, roll forming, roofing systems, structural fabrication, and general industrial processing.

Can you provide long-term supply contracts?
Yes. We support long-term agreements with stable monthly supply to ensure consistent material availability for manufacturers and distributors.
