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 one of the most commonly used square tube materials at present. Its main component is carbon and a small amount of other elements. The advantages of this material are high strength, good toughness, easy processing, and relatively low cost. It is widely used in construction, machinery, automobiles and other fields. However, carbon structural steel also has shortcomings. It is easily corroded and oxidized 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 for its high strength, corrosion resistance, heat resistance, fatigue resistance and other characteristics. Among them, the more common steel types include Q345B, 16Mn and other steel types, which are mainly used in bridges, ships, pipelines and other fields. Common standards include ASTM A500.

3. Stainless steel
Stainless steel is a square tube material with excellent corrosion resistance. Its main components are chromium and nickel. It is characterized by being non-rusting, non-corrosive and non-deformable, and is widely used in construction, medical, food and other industries that require high hygiene, high temperature resistance and corrosion resistance.

4. Aluminum alloy
Aluminum alloy square tube has the characteristics of light weight, high strength and good corrosion resistance. It is a material widely used in various fields. In addition, aluminum alloy square tubes also have the advantages of wear resistance and good electrical conductivity, and are widely used in light industry, high-end construction and other fields.

To sum up, there are many types of square tube materials, each with its own unique properties and application scenarios. When selecting materials, it is necessary to select the most suitable material according to the specific use environment and requirements to ensure the quality and service life of the square tube.
