Frequently Asked Questions
Q1: What is the difference between 2B finish and other finishes (e.g., BA, No.1)?
A: 2B finish is a bright, cold-rolled surface with a moderate reflectivity, while BA finish is a mirror-like bright annealed surface. No.1 finish is a hot-rolled, matte surface. 2B is commonly used for general fabrication, welding, and applications where a uniform appearance is desired.
Q2: Can this plate be used for outdoor applications?
A: Yes, 304 stainless steel has good corrosion resistance, but for severe marine or high-chloride environments, we recommend 316L grade. For moderate outdoor use, 304 with 2B finish is suitable, especially if properly maintained.
Q3: What thickness tolerance do you guarantee?
A: We guarantee a thickness tolerance of ±0.05mm for all plates within the 0.5mm–3mm range, ensuring consistent quality for welding and forming.
Q4: Do you provide custom cutting or special sizes?
A: Yes, we offer custom width and length cutting according to your specifications. Minimum order quantity may apply, but we are flexible to accommodate your project needs.
Q5: Is the plate suitable for food-grade applications?
A: 304 stainless steel is widely used in food processing equipment due to its non-toxic nature and resistance to acidic foods. Our plates meet ASTM A240 requirements, which are compliant with food-grade standards.
Q6: How do you ensure the quality of each shipment?
A: We have a rigorous quality control process including chemical analysis, mechanical testing, surface inspection, and dimensional checks. Each batch comes with a mill test certificate (MTC) as per ASTM A240.
Q7: What is the lead time for a typical order?
A: For standard sizes (1000mm x 2000mm), lead time is about 7–15 working days. Custom sizes may take 15–25 working days, depending on quantity. We can expedite rush orders upon request.
Q8: Can you provide samples before bulk order?
A: Yes, we offer free samples (shipping cost collected) for quality evaluation. Contact our sales team to arrange sample delivery.
