What materials are square tubes (SHS) made of?

Common materials for square tubes (SHS) mainly include the following:

1. Carbon structural steel

   Carbon structural steel is a commonly used material for square tubes due to its high strength, good toughness, ease of processing, and relatively low cost. It is widely used in construction, machinery, automobiles, and other fields. However, it is prone to corrosion and oxidation and requires frequent protective treatment.

2. Low alloy high strength steel

Low-alloy high-strength steel is a new type of square tube material that is widely used due to its high strength, corrosion resistance, heat resistance, and fatigue resistance. The more common steel types include Q345B, 16Mn, and others, which are mainly used in bridges, ships, pipelines, and other fields. ASTM A500 is a common standard for this type of steel.

3. Stainless steel

Stainless steel is a material made of chromium and nickel that is highly resistant to corrosion. It is commonly used in industries such as construction, medicine, and food that require high levels of hygiene, temperature resistance, and corrosion resistance due to its non-rusting, non-corrosive, and non-deformable properties.

4. Aluminum alloy

The aluminium alloy square tube is lightweight, strong, and has good corrosion resistance, making it a widely used material in various fields. It also has good wear resistance and electrical conductivity, making it popular in light industry, high-end construction, and other fields.
