how strong is square tube

Square tube usually refers to square pipe material, and its strength depends on its size and material. The larger the wall thickness and side length of a square tube, the stronger its structural strength and load-bearing capacity in general. The material of square tube can also affect its strength, for example, stainless steel square tube is more corrosion-resistant than carbon steel square tube, but carbon steel square tube may have higher mechanical strength.
Only by choosing good quality square tubes can the quality of manufactured products be improved.
There are three main aspects to choose from:

1. Tensile strength. Tensile strength is the most basic performance of square tubes. Therefore, the greater the tensile strength, the better the performance of square tubes. Therefore, we choose square tubes with greater tensile strength so that square tubes can bring us greater help.

2. Compression resistance. The current compression resistance of square tubes is relatively good.

3. Bending resistance. Some manufactured products need to be bent, so it must be made clear when purchasing square tubes. You can choose square tubes from local factories in Wuxi or cold-rolled square tubes.
