Applications for Seamless Square Tubes

Seamless square tubes are metal tubes with a square cross-section, and they have various applications, including:

Structural supports and seamless square tubes are commonly used as structural materials for beams, columns, and walls in the construction field, as well as for scaffolding and formwork.

Fluid conveyance, due to the seamless square tube's ability to withstand internal or external radial pressure, and its lower hardness and fatigue resistance, they are also used as pipelines for conveying low-pressure fluids such as oil, gas, and water.

Mechanical manufacturing, seamless square tubes are used in the production of various mechanical parts and equipment, such as bearing shells and jack sleeves.

Furthermore, seamless square tubes are extensively used in bridges, railways, vehicles, ships, metallurgy industry, agricultural vehicles, greenhouses, automotive industry, highway guardrails, container frames, furniture, decoration, and steel structure fields.

Advantages of seamless square tubes include high strength, corrosion resistance, excellent machinability, attractive appearance, and high reliability. They typically feature hollow cross-sections and are manufactured through extrusion or cold drawing processes, performing better under pressure compared to traditional welded square tubes.
