Application of square tubes

Square tubes are a common structural pipe material with high strength and good durability, and are widely used in many fields. The following are the main uses of square tubes:

Machinery manufacturing: Square tubes are widely used in machinery manufacturing to manufacture various mechanical parts and structural parts.
Construction industry: Square tubes are used in the construction industry to make building components, brackets and frames, such as glass curtain walls, door and window decorations, steel structures, etc.
Agricultural construction: Square tubes are also used in agricultural construction, such as the skeleton of agricultural greenhouses and the skeleton of agricultural machinery.
Automobile industry: Square tubes are used in automobile manufacturing as structural components of automobiles to enhance the strength and durability of vehicles.
Power industry: Square tubes are used for brackets of power facilities and supporting structures of transmission lines.
Furniture manufacturing: Square tubes are often used to make furniture frames and structural components, such as steel and wood furniture.
Other fields: Square tubes are also used in shipbuilding, container manufacturing, home appliance manufacturing, fire protection facilities and many other fields.
Characteristics of square tubes
Square tubes are long steel strips with hollow cross-sections and no seams around them. The tubes are hollow inside and have a set cross-sectional area. They are mainly used to transport fluids, such as oil, natural gas, coal gas, water and certain solid materials. Square tubes are subjected to relatively uniform forces when subjected to internal or external radial pressure, but when subjected to plane bending, the bending strength of square tubes is greater than that of round tubes. Therefore, they are often used in occasions that require higher bending strength, such as agricultural machinery frames and steel and wood furniture.
