Square tubes are a type of lightweight thin-walled steel tubes with a hollow square cross-section, also known as cold-formed steel profiles. They are shaped steel with square cross-sectional shapes and dimensions, which are made from Q235 hot-rolled or cold-rolled steel strips or coils as the base materials. After cold bending processing and forming, they are then manufactured through high-frequency welding. Square tubes have the following characteristics:
High Strength: The cross-section of square tubes is square or rectangular. This structure gives them a high bending moment resistance. When subjected to force, they can effectively distribute the pressure, improving the overall structural stability, and are capable of bearing relatively large pressure and tension.
Light Weight: Compared with round tubes, square tubes have a lighter weight per unit area. This is beneficial for reducing the self-weight of buildings or other structures. At the same time, they are also easy to carry and install. During the construction process, it can reduce the input of manpower and materials, and improve the construction efficiency.
Good Corrosion Resistance: The main components of square tubes are iron and carbon. Some square tubes also undergo treatments such as galvanizing, painting, or anodizing on their surfaces to form a protective film. This can effectively prevent oxidation and corrosion, enabling them to maintain good performance in harsh environments such as humid, acidic, and alkaline conditions, extending their service life, and reducing the costs of maintenance and replacement.
Good Machinability: Square tubes can be easily processed into various shapes, such as straight sections, elbows, tees, etc., which is convenient for connection with other components. They can be cut, bent, welded, drilled, and other processing operations as required to adapt to different construction environments and design requirements.
