Hot Selling Q345 Square Rectangular Tube Q345b Square Tube Rectangular Tube
Carbon steel square tube is a square cross-section steel tube composed of carbon, manganese, silicon, phosphorus, sulfur and other elements. It has good mechanical properties and a wide range of applications. Carbon steel square tube is mainly composed of carbon and iron elements, and may contain a small amount of alloying elements such as manganese and silicon to improve its mechanical properties and corrosion resistance. Common materials include Q195, Q215, Q235 and Q345, etc., each material has its specific application scenario. For example, Q195 is suitable for building structures that do not require corrosion resistance, while Q345 is suitable for heavy building structures and heavy-loaded parts in machinery manufacturing.
