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. Angle steel can make up different stress components according to the different needs of the structure, as the connection between components.

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.

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.

Round steel is a solid strip of steel with a circular section. Its specification is expressed in diameter, in millimeters (mm)

The square and rectangular pipe refers to a steel pipe with a square or rectangular section, which is hollow and belongs to the steel pipe. The shape of the rectangular tube is square or rectangular. Such a structure is very beneficial to the support of objects and the construction of other objects. For enterprises, the rectangular tube has a relatively long life and stable performance. of. The production process of the square tube is simple, the technical requirements are relatively low, and it is very suitable for mass production and procurement. It also has great advantages in terms of price, etc. Effect.

Galvanized steel plate is to prevent the surface of the steel plate from corrosion, extend its service life, coated with a layer of metal zinc on the surface of the steel plate, this zinc coated thin steel plate is called galvanized plate
