Structural Steel Tube Properties & Specifications

Structural steel tube materials cover a variety of types, such as carbon steel and alloy steel. It is widely used in different industrial fields. Especially in chemical, petroleum, textile, medical, food, machinery and other industries, it can be used as a material for corrosion-resistant pipes and structural parts and parts.

Structural Steel Tube


Strength and stiffness: The structural steel tube usually has high strength and stiffness, and can withstand large pressure and bending moments. This makes it an important component in buildings, Bridges and other large structures.

Corrosion resistance: high-quality steel pipes are specially treated, such as galvanized or coated with anti-corrosion coating, which can resist corrosion and oxidation and extend the service life.

Plasticity: steel pipe material has good plasticity. It is easy to perform machining operations such as cutting, bending and welding to meet complex structural requirements.

Economy: Compared with other structural materials, this steel pipe has the advantages of high cost effectiveness and easy installation. This is conducive to reducing the total cost of the project.
