Frequently Asked Questions (FAQ):
Q: What is the difference between 2B and BA finish?
A: 2B is a cold-rolled, heat-treated, pickled, and skin-passed finish with a matte appearance. BA (Bright Annealed) is processed under an inert atmosphere to produce a bright, reflective surface without pickling. BA is often used for decorative applications where aesthetics are important.Q: Can you supply coils with a No.4 brushed finish?
A: Yes, No.4 brushed finish is available for grades 201, 304, and 430. It features a unidirectional satin texture achieved by mechanical brushing and is popular for architectural and food processing equipment.Q: What is the minimum order quantity (MOQ)?
A: MOQ is typically 5 tons per grade and finish, but we can negotiate smaller quantities for trial orders. Please contact us for specific requirements.Q: How do you ensure consistent quality across different batches?
A: We implement strict in-process and final inspections according to ASTM/JIS standards. Each coil is tested for thickness, width, surface quality, and mechanical properties. Our quality system is certified under ISO9001:2015.Q: Do you provide slitting services for narrow width coils?
A: Yes, we offer slitting down to 50mm width, with custom packaging such as eye to wall or eye to sky. Please provide your exact specifications for a feasibility check.Q: What is the lead time for a standard order of 304 stainless steel coils with 8K mirror finish?
A: Lead time is typically 15–20 working days after order confirmation, depending on the quantity and finish complexity. For urgent orders, expedited service may be available.Q: Are your coils suitable for outdoor use?
A: For outdoor applications, we recommend grade 304 or 316 (if needed) due to their higher corrosion resistance. Grade 430 can be used in mild environments but may require protective coating. Our technical team can advise based on your specific climate conditions.Q: Do you offer samples before bulk order?
A: Yes, samples (A4 size or small coil pieces) are available at a nominal cost, which can be refunded upon placing a bulk order. We also provide free technical documentation.
