Frequently Asked Questions

Q: What are the primary differences between DC01 and DC04 grades?

DC01 is a general-purpose cold-rolled steel for standard fabrication, while DC04 is specifically engineered for deep drawing applications, offering significantly higher ductility and formability.

Q: Can you provide custom processing for steel coils?

Yes, we provide a comprehensive one-stop service including fiber laser cutting, precision bending, punching, welding, and fully automatic painting based on your specific technical requirements.

Q: How is the steel protected during international shipping?

We utilize standard seaworthy export packing, which includes reinforced wooden pallets and high-grade plastic protection to prevent moisture ingress and physical damage during transit.

Q: Which international standards do your steel products comply with?

Our products are manufactured in strict accordance with BS, EN, GB, AiSi, ASTM, DIN, and JIS standards to ensure seamless global compatibility and quality compliance.

Q: Do you offer free samples for quality verification?

Absolutely. We provide free material samples and express shipping worldwide to allow your engineering team to verify the quality before committing to a bulk order.

Q: What are the typical payment terms for large volume orders?

Our standard terms are 30% T/T in advance with the 70% balance due before shipment, or we can accept L/C at sight for qualified large-scale corporate orders.
