Audited Supplier Square Tube is a metal Tube with a square or rectangular cross-section, usually made of materials such as steel, stainless steel, aluminum alloy, etc. This type of Tube has excellent mechanical properties and a wide range of applications, therefore it has received widespread attention and use in practical engineering.
The manufacturing process of Square Tube mainly includes steps such as unpacking, leveling, curling, welding, and rolling of strip steel. Through these process steps, the strip steel can be processed into Square Tube with the required cross-sectional shape and size. Due to the continuous development of manufacturing processes, the variety and specifications of Square Tube are becoming increasingly diverse, meeting the needs of different engineering fields.
Square Tube has good strength and stiffness, and can withstand large pressure and tension, so it is widely used in various steel structure engineering. In the field of architecture,Square Tube can be used as the main material for components such as columns, beams, and trusses, improving the load-bearing capacity and stability of buildings. In the field of mechanical manufacturing, rectangular tubes can also be used to manufacture various mechanical equipment and components, improving the strength and reliability of the equipment.
