Applications of Seamless Square Tubes

Seamless square tubes are metal tubes with a square cross-section, featuring a wide range of 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 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 fabricate 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 industry, agricultural vehicles, greenhouses, automotive industry, highway guardrails, container frames, furniture, decoration, and steel structures.

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, outperforming traditional welded square tubes in pressure-bearing capabilities.
