This article compares the strength of rectangular tubes and square tubes in terms of four aspects: strength, stiffness, stability, and load-bearing capacity. It explains in detail the characteristics and advantages of each type of tube. Hunan Standard Steel Co., Ltd is a professional manufacturer of rectangular and square tubes, offering products in various specifications and sizes.

1. Intensity

 Rectangular tubes have a significantly higher bending strength than square tubes, making them more reliable for carrying large loads. This is due to the formula, which shows that rectangular tubes have a bending strength that is about 15% higher than that of square tubes.

2. Stiffness

Stiffness is a crucial indicator for measuring the performance of structural materials. It is also a key factor in evaluating rectangular and square tubes. The formula calculation results demonstrate that rectangular tubes exhibit significantly better stiffness than square tubes. Additionally, changes in their cross-sectional dimensions have a lesser impact on stiffness, making them suitable for engineering projects that require high stiffness.

3. Stability

 Rectangular tubes are more stable than square tubes due to their larger shear area and moment of inertia. However, there may be a problem of bending stress concentration at the four corners of the rectangular tube, which can be solved with proper design and manufacturing.

4. Bearing capacity

Bearing capacity is a crucial material indicator. Rectangular tubes have a load-bearing capacity approximately 20% higher than square tubes, making them capable of withstanding greater loads in the same engineering project.
