Angle steel,commonly known as angle iron ,is a carbon structural steel used in construction. It is a long strip of steel with two sides perpendicular to each other. It is a profile steel with simple section . Angle steel is divided into equal Angle steel and unequal Angle steel. The raw billet for the production of steel angles is low carbon square billet, and the finished Angle steel is devided into hot rolled, normalized or hot rolled state.

Channel steel is a long strip of steel with a groove section. Channel steel is a carbon structural steel used in construction and machinery. It is a section steel of complex section, and its section shape is trough. Channel steel is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing. In use, it is required to have better welding, riveting and comprehensive mechanical properties.

H-shaped steel is a section of H-shaped steel, also known as universal steel beam, wide edge (side) I-steel or parallel flange I-steel.

Rebar is commonly known as hot rolled ribbed bar. The grade of ordinary hot rolled steel bar consists of the minimum yield point of HRB and grade. H, R and B are the first letters of hotrolled, Ribbed and Bars respectively. Rebar can be divided into three categories according to strength :HRB300E, HRB400E, HRB500E, HRB600E, etc.
The thread specification range of rebar is generally 6-50mm. We usually involve more are 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 25mm, 28mm, 32mm, 36mm, 40mm and so on. National allowable deviation :6-12mm deviation in ±7%, 14-20mm deviation in ±5%, 22-50mm deviation in ±4%. Generally, the fixed length of rebar is 9m and 12m, among which 9m long thread is mainly used for normal road construction and 12m long thread is mainly used for bridge construction.

I-beam, also known as steel beam (English name universal Beam), is a long steel with the section of the I-shaped. I-section steel is divided into hot rolIed I-beam  and lightweight  I-beam
I-beam is mainly divided into ordinary I-beam, light I-beam, low alloy light I-beam .
The wing of ordinary I-beam and light I-beam gradually thinner from the root to the side, with a certain Angle. The type of ordinary I -beam and light I-beam is expressed by the Arabic number of its waist height in centimeters. . I-beam is mainly used in building structure, curtain wall engineering, mechanical equipment ,vehicle manufacturing and so on.
