Advantage Of Using Rectangular Tube

High strength

Structural Stability

The cross-sectional shape of rectangular steel pipes is rectangular, which provides greater strength and stiffness and is suitable for structures that require high pressure and load, such as bridges and large buildings. Its structural stability is superior to other shapes of steel pipes

Light Weight

Light Weight

Compared to solid steel of the same strength, rectangular steel pipes are lighter in weight. This makes it more convenient for construction and transportation, reducing construction costs and labor demand.

Strong Compressive Strength

Strong Compressive Strength

Rectangular steel pipes are made through cold bending or hot rolling processes, with a smooth surface and high compressive strength. This makes it widely used in fields such as construction, machinery manufacturing, and automotive industry

Good Processability

Good Processability

Rectangular steel pipes are made of soft material, easy to process, and can be processed through cutting, welding, cold bending, and other techniques. This good processability provides greater design freedom for various construction and manufacturing projects

Strong Corrosion Resistance

Strong Corrosion Resistance

Rectangular steel pipes can be treated with advanced coating and plating techniques to improve their corrosion resistance. This makes rectangular steel pipes have a longer service life in corrosive environments such as marine environments and chemical industries

Good Cross-Sectional Characteristics

Good Cross-Sectional Characteristics

Compared with wide flange H-beams and circular steel pipes of the same weight or cross-sectional height, the bending stiffness of rectangular steel pipes in both axial directions is 1.3 times that of circular steel pipes, which is close to the bending stiffness of H-beams in the strong axial direction.

  • how to calculate weight of rectangular tube?
    There are two ways to calculate the weight of a rectangular tube: theoretical weight calculation and actual weighing
    The weight per meter of rectangular pipe (kg)=[(outer diameter inner diameter) x inner diameter] x 0.02466, where 0.02466 is a fixed coefficient. During operation, it is necessary to accurately measure the outer and inner diameters of the pipe, which are the basis for calculation. For example, the weight per meter of a rectangular tube with an outer diameter of 50mm and an inner diameter of 30mm is [(50-30) × 30] × 0.02466=14.796kg. In addition, the wall thickness of the pipe is also a key factor affecting weight and cannot be ignored. Professional tools must be used during measurement to ensure accurate and error free data. Finally, the obtained result is the weight per meter. If the total weight is required, it needs to be multiplied by the length of the pipe material.
    Actual weighing is to calculate the weight of the rectangular tube based on the actual weight value.

  • how is rectangular tube measured?
    Method for measuring the length of rectangular tubes
    1. Use a steel ruler or tape measure to measure along the length of the pipeline.

    2. Use measuring instruments for measurement, such as measuring instruments, laser rangefinders, etc.

    Attention: When measuring the length, it is necessary to ensure that the measuring tool is placed flat and perpendicular to the length direction of the pipeline.

    Method for measuring the width of rectangular tubes
    1. Use a steel ruler or tape measure to measure along the width direction of the pipeline, or use a measuring instrument for measurement.

    If the width of the rectangular tube is irregular, multiple measurements are required.

    Attention: When measuring the width, it is necessary to ensure that the measuring tool is placed flat and perpendicular to the width direction of the pipeline.

    Measurement method for thickness of rectangular tube
    1. Use an outer diameter caliper or inner diameter caliper to measure along the four corners of the rectangular tube. If the rectangular tube is long, multiple measurements are required and the average value is taken.

    2. Use ultrasonic measuring instruments for measurement.

    Attention: When measuring thickness, it is necessary to ensure that the measuring tool is horizontal or perpendicular to the direction of the pipeline.
