SS400 Hot Rolled Coil
JIS structural hot rolled coil
SS400 (JIS G3101) is the Japanese-standard carbon structural grade, widely specified across Southeast Asia, Japan-related supply chains and general export fabrication. We supply SS400 hot rolled coil 2–25 mm with JIS-compliant mill certificates.
Choosing between SS400 and Q235B
Mechanically the grades are close twins; the difference is mostly paperwork. If your customer's drawings say JIS, quote SS400; if GB or no standard is stated, Q235B typically prices better. We quote both on the same enquiry so you can compare directly.
Common applications
Structural sections feedstock, machinery bases, containers, and as input material for welded pipe and cold forming.
