Square tube is a hollow square pipe material with high strength, corrosion resistance, and easy processing. It has a wide range of applications in various fields such as construction, machinery manufacturing, automotive industry, agriculture, etc. The following is a specific introduction:
1. Construction field
      Structural support: In building structures, square tubes are often used as structural components such as columns and beams to support the weight of the building. For example, in some lightweight steel structure buildings, square tubes can form a frame structure to provide stable support for the building.
      Curtain wall skeleton: Square tubes can be used as the skeleton material for curtain walls, used to fix curtain wall panels such as glass, stone, etc. It can provide sufficient strength and rigidity for the curtain wall, and can also adjust various shapes and installation methods according to design requirements.
      Scaffolding: Square tubes are also commonly used materials when building scaffolding. It can be assembled into scaffolding of various shapes and heights through fasteners and other connectors, providing a safe working platform for construction workers.
2. In the field of mechanical manufacturing
      Mechanical frame: Many mechanical equipment frames are made of square tubes, such as the frames of automated production lines and the brackets of conveyor equipment. Square tubes can provide stable support and structural foundation for equipment, ensuring its stability and reliability during operation.
      Workbench: In some machining workshops, square tubes are often used to make workbenches. Its high strength and smooth surface can meet the requirements of processing operations, and various fixtures and tools can also be installed on the workbench as needed.
3. In the field of automotive industry
      Frame: The frame of a car sometimes uses square tubes, especially for some light trucks, modified vehicles, or special vehicles. Square tubes can form a frame structure with good strength and stiffness through reasonable design and welding, bearing the weight and various driving forces of vehicles.
      Body structure: Square tubes are also used in some parts of the car body, such as door frames, roof frames, etc. Square tubes can improve the overall strength and safety of the car body, while reducing its weight and enhancing its fuel economy.
4. Decoration field
      Door and window frames: Square tubes can be processed into door and window frames of various sizes and shapes, with the characteristics of beauty and durability. Compared with traditional wood or aluminum alloy door and window frames, square tube frames have higher strength and can achieve different decorative effects through surface treatment.
      Decorative design: In indoor decoration, square tubes can be used to create various decorative designs, such as partitions, screens, display stands, etc. By bending and welding the pipes, unique artistic effects can be created to meet different decoration styles and design needs.
5. Agricultural field
      Greenhouse: Square tube is one of the commonly used materials for building greenhouses. It can serve as the skeleton of the greenhouse, supporting the greenhouse film and providing a suitable growth environment for crops. Square tubes have the characteristics of corrosion resistance and high strength, which can resist the erosion of natural environments such as wind, sun, and rain.
      Irrigation equipment: In agricultural irrigation systems, square tubes can be used to make irrigation pipes and brackets. It can withstand a certain amount of water pressure to ensure the smooth delivery of irrigation water, while providing support for irrigation equipment such as nozzles.
6. Other fields
      Furniture manufacturing: In furniture manufacturing, square tubes can be used to make frames for tables and chairs, footrests for sofas, etc. It can provide stable structural support for furniture, while also giving furniture a modern and fashionable feel through surface treatment and decoration.
      Sports facilities: Some sports facilities, such as basketball hoops, football doors, fitness equipment, etc., also use square tubes as the main structural material. The strength and stability of square tubes can meet the requirements of sports facilities during use, ensuring the safety of users.
