It is mainly divided into two categories: equilateral Angle steel and unequal Angle steel, among which unequal Angle steel can be divided into unequal equal thickness and unequal thickness.

Rebar is a hot rolled ribbed bar commonly known.The grade of ordinary hot - rolled steel bar consists of HRB and the minimum yield point of the grade.H, R and B are the first letters of Hotrolled, Ribbed and Bars respectively.
Hot rolled ribbed steel bar is divided into two grades HRB335 (the old brand name is 20MnSi), three grades HRB400 (the old brand name is 20MnSiV, 20MnSinB, 20MnTi) and four grades HRB500.

An economical section shaped like a capital Latin H, also called universal beam, wide flange (edge) I-beam, or parallel flange I-beam. The cross section of H-shaped steel usually includes two parts: web and flange plate, also known as waist and edge.

Round steel is divided into three types: hot rolled, forged and cold drawn.Hot rolled round steel is 5.5-250 mm in size.Among them: 5.5-25 mm small round steel mostly in straight bundles supply, commonly used for reinforcing bars, bolts and various mechanical parts;Round steel larger than 25 mm, mainly used in the manufacture of machine parts, seamless steel tube billet, etc.
