Looking for JIS G3101 SS400 plates for structural projects, fabrication, or OEM production?
At Hindustan Steel Corporation, we supply SS400 mild steel plates with cut-to-size services, MTC, and third-party inspection for both domestic and export buyers.
SS400 is one of Japan’s most popular general structural steel grades, known for its workability, weldability, and economy.
JIS G3101 SS400 is a Japanese Industrial Standard for hot-rolled mild steel plates, defined under JIS G3101 specification.
SS400 stands for:
Key Features:
We supply SS400 plates to fabricators, OEMs, exporters, and contractors across India, UAE, South Africa, and Saudi Arabia.
