Practical Knowledge About Profiles

1、Classification of profiles

① Square steel – hot-rolled square steel, cold drawn square steel.
② Round steel – hot-rolled round steel, forged round steel, cold-drawn round steel.
③Wire rod.
④Flat steel.
⑤ spring flat steel.
⑥Angles – equilateral angles, unequal angles.
⑦ Triangular steel.
⑧Hexagonal steel.
⑨ bow-shaped steel.
⑩Oval steel.

2、Complex section steel

① I-beam – ordinary I-beam, light I-beam
② channel – hot-rolled channel (ordinary channel, light channel), bending channel 
③ H-beam (also known as wide leg I-beam)
④ rail – heavy rail, light rail, crane rail, other special rails
⑤ Window frame steel
⑥Steel sheet piles
⑦Bending section steel – cold-formed steel, hot-formed steel
⑧Other
