Applications:

Square rectangular tubes play a key role in many fields with their unique cross-sectional shape, excellent mechanical properties and a variety of specifications. The following are their wide range of product application scenarios: ​

1. Construction field ​
In the construction of building structures, square rectangular tubes are indispensable materials. The frame structure of high-rise buildings uses high-strength square rectangular tubes. With their good compression and bending resistance, they effectively bear the vertical and horizontal loads of the building and ensure the stability and safety of the building. When building industrial plants, steel structures composed of large-size square rectangular tubes can meet the needs of large-span spaces and adapt to the installation and operation of heavy machinery. In addition, square rectangular tubes are also commonly used to build stair handrails, balcony railings, fences, etc. Their various surface treatment processes (such as hot-dip galvanizing and spraying) not only improve the aesthetics, but also enhance the anti-corrosion performance and extend the service life. ​
2. Transportation ​
In the automobile manufacturing industry, square rectangular tubes are used to manufacture key parts such as frames and chassis. Due to their light weight and high strength, they can reduce the weight of the vehicle body and improve fuel economy while ensuring the overall rigidity of the vehicle. In the field of rail transit, square and rectangular tubes are used to make the skeleton structure of train carriages, providing stable space support for the interior of the carriages, and enhancing the safety of train operation with good impact resistance. In shipbuilding, square and rectangular tubes are suitable for deck railings, cabin partition frames, etc., and their corrosion-resistant surface treatment types (such as stainless steel, special anti-corrosion coating) can effectively resist seawater erosion. ​
3. Mechanical Manufacturing​
The frames and support structures of mechanical processing equipment often use square and rectangular tubes. Their regular shape facilitates the installation and fixation of parts, and the stable structure can ensure the accuracy and reliability of the equipment during operation. In the field of conveying machinery, the conveyor belt bracket made of square and rectangular tubes can withstand large tension and pressure to ensure smooth material transportation. In addition, various agricultural machinery, such as harvesters and tractor frames, use square and rectangular tubes to meet strength requirements, reduce the weight of the whole machine, and improve the flexibility and operating efficiency of the machinery. ​
4. Energy and Chemical Industry​
In the petrochemical industry, square and rectangular tubes are used to build pipeline brackets and equipment frames. Its high temperature and corrosion resistance (such as special alloy steel material, specific anti-corrosion treatment) can adapt to complex chemical environments and ensure production safety. In the field of wind power generation, square and rectangular tubes, as components of wind turbine towers, support huge impellers and nacelles with high structural strength and stability, and resist the influence of severe weather such as strong winds. Solar photovoltaic brackets also use a large number of square and rectangular tubes, and their various specifications can be flexibly adapted to different installation angles and terrains to ensure that photovoltaic panels receive sunlight efficiently.
