Applications for Seamless Square Tubes

Seamless square tube is a metal tube with a square cross-section, offering a variety of uses, 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.

Transfer fluids; Seamless square tubes are also used for conveying low-pressure fluids like oil, gas, and water due to their ability to withstand internal or external radial pressure, as well as 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, jack sleeves, etc.

In addition, seamless square tubes are widely used in bridges, railways, vehicles, ships, metallurgical industries, agricultural vehicles, greenhouses, automotive industries, highway 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 sections, manufactured through extrusion or cold drawing processes. Compared to traditional welded square tubes, seamless square tubes perform better under pressure.
