As ST52-3 I-beam΄s name suggests, ST52-3 I-beam is a kind of "workers" shaped cross-section steel, and the inner surface of the upper and lower flange inclination is generally 1: 6, resulting in ST52-3 I-beam cross section in the main characteristics of the two planes a huge difference in the application and it is difficult to play just the strength characteristics. ST52-3 I-beam structure has been determined torsional performance short board.
