Frequently Asked Questions (FAQ)
Q: What is the difference between No.4, BA, and Mirror finishes?
A: No.4 finish has a brushed/velvet texture with a maximum Ra of 0.4 µm; BA (bright annealed) is a reflective, mirror-like surface achieved by annealing in a controlled atmosphere; Mirror finish is polished to a high gloss with Ra up to 0.1 µm. Each serves different aesthetic and functional needs.Q: Can I order a mix of grades in one coil?
A: No, each coil is made of a single grade. However, we can supply multiple coils of different grades within one order to meet your project requirements.Q: What is the minimum order quantity (MOQ)?
A: MOQ depends on the grade and finish. Typically, for standard sizes, MOQ is 5 tons per coil. For non-standard dimensions, MOQ may be higher. Contact us for specific details.Q: Do you provide thickness tolerance data?
A: Yes. We adhere to ASTM A480 tolerances. For example, for thickness 0.3-0.5mm, tolerance is ±0.02mm; for 0.5-1.0mm, ±0.03mm, etc. Detailed tolerance tables are available upon request.Q: Are these coils suitable for food contact surfaces?
A: Yes, grades 304 and 316 are widely used in food processing equipment. However, we recommend confirming local food safety regulations. Our HACCP certification supports hygienic design.Q: How are the coils packed for export?
A: Coils are packed with anti-rust paper, plastic film, and steel strapping, then placed on wooden pallets or crates. For sea freight, we use waterproof wrapping and fumigation-free wood materials as required.Q: Can you cut the coil to specific widths?
A: Yes, we offer slitting services to produce custom widths, typically from 100mm up to 1500mm, with a tolerance of ±0.5mm.Q: What is the typical lead time?
A: For standard sizes and finishes, lead time is 15-20 days after deposit. For custom orders, it may be 25-30 days. We also offer faster delivery options for urgent projects.
