Channel steel is a long stripe of steel with a fluted  section , construction and mechanical use of carbon structural steel, is a profile steel with  complex section , its section shape is groove shape. Channel steel is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing., Channel steel is often used together with I steel.
Channel steel is divided into ordinary u-steel and light Channel steel. The specification of hot rolled ordinary Channel steel is 5-40#. The specification of hot rolled flexible Channel steel is 6.5-30# after  agreement between the purchaser and the supplier.

It is a long strip of steel with an I-shaped cross section. I-beams are divided into ordinary I-beams and light I-beams. It is a section steel with an I-shaped cross-section. Whether the I-shaped steel is ordinary or light, because the cross-sectional size is relatively high and narrow, the moment of inertia of the two main axes of the cross-section is quite different, so it can only be directly used for members that are bent in the plane of its web or formed into a lattice-type force-bearing member. It is not suitable for axial compression members or members with bending perpendicular to the web plane, which limits its application range. I-beams are widely used in buildings or other metal structures. The selection of I-beams in structural design should be based on its mechanical properties, chemical properties, weldability, structural dimensions, etc. to select reasonable I-beams for use.

Steel rebar is a steel material used for reinforced concrete and prestressed reinforced concrete. Its cross section is usually round, sometimes square with rounded corners. The main types of rebar include plain round bars and deformed bars. Plain round bars are actually small round bars and coils of ordinary low-carbon steel, while deformed bars have ribs on the surface, usually 2 longitudinal ribs and transverse ribs evenly distributed along the length. The shape of the transverse ribs can be spiral, herringbone or crescent.
