Frequently Asked Questions

Q: What are the primary applications of carbon steel coils?                                    

They are widely used in construction for roofing panels, in the automotive industry for chassis and body parts, in shipbuilding for structural hulls, and in the manufacture of boilers and pressure vessels.

Q: Can you provide materials for bridge and vessel construction?                                    

Yes, we provide specialized bridge plates and vessel steel designed to withstand high pressure and extreme environmental loads, adhering to international safety standards.

Q: Do you offer customized thickness and widths?                                    

Absolutely. We provide OEM/ODM services, including precise slitting and cutting to meet your specific thickness (2.0mm-13.5mm) and width requirements.

Q: What is the difference between hot-rolled and cold-rolled coils?                                    

Hot-rolled coils are processed at high temperatures, offering better toughness and weldability for structural use. Cold-rolled coils are processed at room temperature, providing a smoother surface and higher dimensional precision.

Q: How do you ensure the quality of the steel?                                    

Our products are manufactured in certified workshops and undergo piece-by-piece inspection according to national QA/QC standards. We also welcome third-party inspections.

Q: What payment methods do you accept?                                    

We accept a variety of payment methods including T/T, L/C, D/A, D/P, Western Union, and Money Gram to accommodate our global clients.
