Square & Rectangular Steel Tubes

Square and rectangular steel tubes are widely used structural materials known for their high strength, uniform shape, and excellent load-bearing performance. With their flat surfaces and clean geometry, these tubes are ideal for construction frameworks, mechanical structures, and architectural applications where both strength and appearance are important.

These tubes are typically manufactured through the ERW (Electric Resistance Welding) process, where high-quality steel strips are formed and welded into square or rectangular shapes. They are available in both MS (Mild Steel) and Galvanized (GI) finishes. The galvanized option provides enhanced corrosion resistance, making it suitable for outdoor and exposed environments, while MS tubes are commonly used for general structural purposes.

Technical Features

Square and rectangular tubes are produced in a wide range of sizes, wall thicknesses, and lengths to meet different project requirements. Common material grades include Q195, Q235, Q345, and equivalent international grades such as ASTM A500 and EN 10219. These tubes offer excellent weldability, strength, and dimensional accuracy, ensuring reliable performance in various structural applications.

Applications

Due to their versatility and structural efficiency, square and rectangular tubes are widely used in building construction, steel structures, bridges, machinery manufacturing, furniture, fencing, and infrastructure projects. Their shape provides better resistance to bending and torsion, making them suitable for both load-bearing and support structures.
