 　　 Angle steel can be composed of various load-bearing components according to different structures, and can also be used as connectors between components. It is widely used in various building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, cable trench supports, power piping, busbar support installation, and warehouse shelves. Angle steel is a carbon structural steel used for construction, and is a simple cross-section steel, Mainly used for metal components and framework of factory buildings. In use, it is required to have good weldability, plastic deformation performance, and certain mechanical strength. The raw steel billet for producing angle steel is low-carbon square steel billet, and the finished angle steel is delivered in hot-rolled, normalized, or hot-rolled state.

 　　It is mainly divided into two types: equal edge angle steel and unequal edge angle steel, among which unequal edge angle steel can be divided into two types: unequal edge equal thickness and unequal edge unequal thickness. 　　The specifications of angle steel are represented by the dimensions of edge length and edge thickness. The specification of domestic angle steel is 2-20, with the number of centimeters of the side length as the number. The same size angle steel often has 2-7 different side thicknesses. Imported angle steel shall be marked with the actual dimensions and edge thickness on both sides, and relevant standards shall be indicated. Generally, those with a side length of 12.5cm or more are large angle steels, those between 12.5cm and 5cm are medium angle steels, and those with a side length of 5cm or less are small angle steels. 　　The ordering of inlet and outlet angle steel is generally based on the specifications required during use, and its steel gra...

 　　 Angled joint sheet metal , also known as angle iron, is a long strip of steel with two sides perpendicular to each other and forming an angle shape. There are two types of angles: equal angle steel and unequal angle steel. The two sides of an equilateral angle steel have equal widths. Its specifications are based on edge width × Edge width × The thickness of the edge is expressed in millimeters. 　　Angle iron is a long strip of steel with two sides perpendicular to each other and forming an angle. There are two types of angles: equal angle steel and unequal angle steel. The two sides of an equilateral angle steel have equal widths. Its specifications are based on edge width × Edge width × The thickness of the edge is expressed in millimeters. As shown in "ě 30 × thirty × 3 "refers to an equilateral angle steel with an edge width of 30 millimeters and an edge thickness of 3 millimeters. It can also be represented by a model, which is the number of centimeters o...

 　　 Channel steel is a long strip of steel with a groove shaped cross-section. A steel section with a groove shape. Channel steel belongs to carbon structural steel used for construction and machinery, and is a complex cross-section steel with a groove shape. Channel steel is mainly used in building structures, curtain wall engineering, mechanical equipment, and vehicle manufacturing. In use, it is required to have good welding, riveting performance, and comprehensive mechanical properties. The raw material for producing channel steel is carbon bonded steel or low alloy steel with a carbon content not exceeding 0.25%. Finished channel steel is delivered in hot working, normalized or hot rolled state, and its specification is expressed in millimeters of waist height (h) * leg width (b) * waist thickness (d), such as 100 * 48 * 5.3, which means channel steel with waist height of 100 mm, leg width of 48 mm, and waist thickness of 5.3 mm, or 10 # channel steel. For channel...

 　　 Square steel : It is a solid bar material. Different from square tubes and hollow ones, they belong to the category of pipe materials. Square section steel, divided into two types: hot rolled and cold rolled; Hot rolled square steel with a side length of 5-250mm; Cold drawn square steel with a side length of 3100mm. Similar bars include round steel, hexagonal steel, and octagonal steel. Square steel can be divided into seam and seamless. Seamed square steel is a square steel pipe made by welding steel plates together. Seamless square steel is made by changing the drawing of seamless steel pipes. Its compressive strength is much greater than that of slotted square pipes. 　　Square steel parameters 　　Material: Q235, 45 # hot rolled, cold drawn square steel Theoretical weight calculation formula: side length X side length X0.00785=kg/m Main purpose: Rolling or processing steel into square sections.
