Frequently Asked Questions (FAQ)
Q1: What is the difference between 2B and BA finish?
A: 2B finish is a cold-rolled, heat-treated, pickled, and skin-passed surface that has a smooth, moderately reflective appearance. BA (Bright Annealed) finish is produced by annealing in a controlled atmosphere to achieve a brighter, mirror-like surface. For general industrial applications, 2B is more common and cost-effective.
Q2: Can you cut the coil into sheets or slitted strips?
A: Yes, we offer slitting, shearing, and blanking services. Please specify your required sheet dimensions or strip width when placing an order. Additional processing charges may apply.
Q3: What is the typical lead time for this product?
A: For standard sizes (0.5mm x 1250mm x C), lead time is approximately 15–20 working days. Custom sizes or special surface treatments may take 25–30 working days. We recommend confirming your order at least 4 weeks in advance for timely delivery.
Q4: Is this coil suitable for food contact applications?
A: Yes, 304 stainless steel is a common food-grade material. Our coils meet the requirements of food processing and kitchen equipment. However, we recommend verifying local food safety regulations (e.g., FDA, EU) for specific uses.
Q5: Do you provide mill test certificates (MTC)?
A: Absolutely. Each shipment comes with a mill test certificate certified by our ISO9001 system, including chemical composition and mechanical properties. Third-party inspection (e.g., SGS, BV) is available upon request.
Q6: What is the minimum order quantity (MOQ)?
A: Our standard MOQ for 304 stainless steel coil is 5 metric tons per size. For trial orders or small quantities, please contact our sales team – we may accommodate based on stock availability.
Q7: Can you supply other thicknesses or finishes?
A: Yes, we supply a full range of 304 stainless steel coils with thickness from 0.3mm to 3.0mm, and finishes including 2B, BA, No.1, and No.4. Feel free to inquire with your specific requirements.
Q8: How is the coil packaged for export?
A: Coils are packed with anti-rust paper, plastic film, and steel pallets or wooden crates. Outer packaging is reinforced for sea freight. We can also customize packaging according to your instructions.
