The hollow structural section is a hollow metal material, usually made of aluminum alloy, steel, stainless steel, and other materials. Its interior is hollow, and its exterior presents various shapes, such as round, square, rectangular, oval, etc. The hollow structural section is widely used in construction, machinery, automobile, aerospace, and other fields, and has the advantages of lightweight, high strength, and corrosion resistance.

The main advantages of the hollow structural section include the following:

Lightweight: There is no solid part in the center of the section of the hollow structural section, so the weight is relatively light, which can reduce the weight of the entire structure, reduce the self-weight of buildings or mechanical equipment, and improve the efficiency of use.

High strength: The cross-sectional shape of the hollow structural section can be designed according to the needs, which can reduce the number of materials used on the premise of ensuring strength, thereby improving the strength and rigidity of the structure.

Corrosion resistance: The hollow structural section is usually made of aluminum alloy, stainless steel, and other materials, which have good corrosion resistance and can be used in harsh environments to prolong its service life.

Convenient processing: The hollow structural section has a simple cross-sectional shape and is easy to process and assemble. It can be processed according to needs, such as cutting, drilling, welding, etc., which is convenient and quick.

Beautiful and generous: the hollow structural section has a beautiful and elegant appearance, and surface treatment can be carried out according to needs, such as spraying, anodizing, etc., to improve the aesthetics and durability of the product.

Types of hollow structural section
