Product Overview

T-Bar is a hot-rolled T-shaped structural steel section manufactured by splitting hot-rolled H-beam. It is classified into three series: TW wide-flange T-Bar, TM medium-flange T-Bar and TN narrow-flange T-Bar. Compared with fabricated welded T sections, hot-rolled T-Bar provides stable metallurgical performance and reliable structural strength.

The product is manufactured according to international standards including GB/T 11263-2017, ASTM A6/A6M-22, EN 10034-2019 and JIS G3192-2018, supporting international engineering projects and third-party inspection requirements.

Our T-Bar portfolio covers TW, TM and TN full series. Standard specifications include TW100×100, TW125×125, TW200×200, TW250×250, TW300×300, TW400×400, TM150×100 to TM450×300, and TN100×50 to TN600×200. Custom hot-rolled T-Bar can also be supplied for heavy-load engineering requirements.

T-Bar is widely applied in industrial construction, bridge engineering, mechanical equipment structures, high-rise buildings, photovoltaic and wind power structures, warehouse systems and marine auxiliary structures. Additional services include cutting, drilling, welding, assembly and NDT inspection according to project requirements.
