FAQ
Q1: What is the difference between SS400 and ASTM A36 steel?
A: Both are mild structural steels. SS400 follows the Japanese JIS standard, while A36 follows the ASTM standard. Their mechanical properties are nearly equivalent.
Q2: Can SS400 plates be galvanized?
A: Yes, SS400 plates can be hot-dip galvanized or zinc-coated for improved corrosion resistance.
Q3: Do you provide mill test certificates (MTC)?
A: Yes, all plates are supplied with MTC EN 10204 3.1 or 3.2 certification.
Q4: What's the minimum order quantity (MOQ)?
A: MOQ is usually 3 tons per size, but we can provide smaller trial orders for new customers.
