Rectangular tube is a common type of pipe material with the following characteristics:
1、 Geometric characteristics
1. Shape rules
       The cross-section of a rectangular tube is rectangular, with its four corners forming right angles. The geometric shape of this rule makes it easy to locate and align during installation and use. For example, in building frame structures, rectangular pipes can be easily connected at right angles to other structural components such as beams and columns to construct a regular building frame, ensuring the stability and geometric accuracy of the building.
2. Efficient use of space
       Compared to circular pipes, rectangular pipes can more effectively utilize space in certain situations. Because its shape better fits the actual installation space and load-bearing requirements. For example, when making furniture, rectangular tubes can be tightly arranged as table legs or frames, which can better utilize flat space and facilitate the installation of other components such as wooden boards, glass, etc. on their surfaces, providing more stable support.
2、 Mechanical performance characteristics
1. Good bending resistance
       Rectangular tubes perform well when subjected to bending forces. Due to the characteristics of its cross-sectional shape, under the action of bending moment, the material is distributed far away from the neutral axis. According to the principles of material mechanics, this can more effectively resist bending deformation. For example, when used as a beam structure in buildings, rectangular pipes can withstand the bending moment generated by larger floor loads and have higher bending strength than circular pipes of the same cross-sectional area.
2. Compressive and torsional performance
      It has good compressive performance. When subjected to axial pressure, the wall of the rectangular tube can evenly distribute the pressure and prevent excessive local deformation. In some application scenarios that require vertical pressure, such as support columns, rectangular pipes can provide stable support.
      However, the torsional resistance of rectangular tubes is relatively weak. Because its cross-sectional shape is not symmetrical in all directions like circular pipes, stress concentration is prone to occur at the corners and walls of rectangular pipes when subjected to torque. But in practical applications, as long as the structure is designed reasonably to avoid or reduce the generation of torque, other mechanical performance advantages of rectangular pipes can be fully utilized.
3、 Processing performance characteristics
1. Easy cutting
      Rectangular tubes are relatively easy to cut. Whether using mechanical cutting (such as sawing) or flame cutting, due to their regular shape, they can cut accurately according to the required size. For example, at the construction site, a regular metal saw can be used to quickly cut rectangular pipes to meet installation requirements of different lengths.
2. Easy to connect
      Rectangular pipes can be connected in various ways, such as welding, bolt connections, etc. When welding, its rectangular cross-section can provide a larger welding area, ensuring the strength of the connection. When connecting with bolts, it is convenient to drill holes on the pipe wall, and due to its flat surface, the nut and bolt can fit well, achieving a reliable connection. For example, when building steel structures, workers can combine rectangular pipes into complex structural systems through welding or bolt connections.
4、 Appearance and decorative features
1. Neat appearance
     The appearance of rectangular tubes is neat and simple, giving people a sense of orderly beauty. This appearance characteristic makes it widely used in fields such as architectural decoration and furniture design. For example, in the exterior decoration of modern buildings, rectangular pipes can be used as metal grilles or decorative lines, creating a simple, elegant, and modern architectural appearance through different arrangements and combinations.
2. Diverse surface treatments
     The surface of rectangular pipes can undergo various treatments, such as galvanizing, painting, sanding, etc. Galvanizing treatment can improve the corrosion resistance of rectangular pipes, enabling them to maintain good performance even in harsh environments such as outdoors and humid environments. Spray painting treatment can change the color of rectangular pipes according to design requirements, to match different architectural styles or decorative themes. Matte treatment can increase the texture of rectangular tubes, making them more decorative.
