IS G3466 standard is a Japanese industrial standard. It’s specified the carbon steel square pipes, used for civil engineering architecture and other structures. JIS G3466 carbon steel square tubes shall be manufactured by forming welded steel tubes (by means of electric resistance welding. Forging welding or automatic arc welding) or seamless steel tubes into square sections, or manufactured by forming a steel sheet in coil into square section or into one pair of channel section followed by a continuous electric resistance welding or automatic arc welding process.

JIS G3466 carbon steel square pipe is used for civil engineering architecture and other structure buildings. There are two grades under JIS G3466: STKR 400 and STKR 490. JIS G3466 Carbon Steel Square pipe shall be manufactured with no heat treated method.
