T-shaped steel, is a cast into the t-shaped steel. Because of its cross-section and the English letter "t" the same name. There are two types of t-section steel: 1. It is the ideal material to replace the double angle steel for welding. The Standard is the same as the h-section steel (GB/T11263-2017) . The utility model has the advantages of strong bending resistance, simple construction, cost saving and light structure weight, etc. . 2. Hot rolled one-time forming t section steel, mainly used in mechanical, filling small hardware section steel use. T shape steel is corresponding to h shape steel. T shape steel with wide Flange, t shape steel with middle flange and t shape steel with narrow flange are represented by TW, TM and TN respectively. It is expressed as follows: Height H width B web thickness t 1 flange thickness t 2. Hot-rolled t section steel is expressed as follows: Height H * Width B * Web thickness t 1 * Flange thickness t 2.
