③ wire;
④ flat steel;
⑤ spring flat steel;
⑥ angle - equilateral angle, unequal angle of steel;
⑦ triangle
⑧ hexagonal
⑨ bowed steel;

③ H-beam (also known as wide-leg beam)
④ rail - heavy rail, light rail, crane rails, other special rails
⑤ window frame steel
⑥ steel sheet pile
⑦ bending steel - cold-formed steel, hot-formed steel
⑧ other
