Applications for Seamless Square Tubes

Seamless square tube is a metal tube with a square cross-section, which has various applications including:

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

Transport fluids; Seamless square tubes are used for conveying low-pressure fluids such as oil, gas, and water due to their ability to withstand internal or external radial pressure, and their lower hardness and fatigue resistance.

Mechanical manufacturing, seamless square tubes are used to produce various mechanical parts and equipment, such as roller bearing shells and jack sleeves.

Moreover, seamless square tubes are extensively used in bridges, railways, vehicles, ships, metallurgical industries, agricultural vehicles, greenhouses, the automotive industry, road guardrails, container frames, furniture, decoration, and steel structures.

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