Our Advantages
Angle steel production
Angle steel belongs to carbon structural steel for construction. It is a simple section steel, mainly used for metal components and frames of factory buildings. In use, it is required to have good weldability, plastic deformation performance and certain mechanical strength. The raw material billet for the production of angle steel is low-carbon billet, and the finished angle steel is delivered in the state of hot rolling, normalizing or hot rolling.High Strength
Adequate inventory
The specifications and inventory of angle steel are complete, expressed in dimensions of edge length and edge thickness. The specification of 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.
Attention to detail
The surface quality of angle steel is stipulated in the standard, and it is generally required that there should be no harmful defects in use, such as delamination, scarring, cracks, etc.
The allowable range of geometric shape deviation of angle steel is also stipulated in the standard, generally including bending degree, side width, side thickness, top angle, theoretical weight, etc., and it is stipulated that the angle steel must not have significant torsion.
Applicable scene
Angle steel can be composed of various stress components according to different needs of the structure, and can also be used as a connector between components. 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 and warehouse shelves, etc.
