Welded Square Steel Pipe

Welded Square Steel Pipe Supplier in China    

A welded square tube is a type of tubular product with a hollow square cross-section. It is formed by processes such as coiling and welding of steel strips or steel plates. Its four corners are usually right angles, and the lengths of all sides are equal, presenting a square appearance.


The base material of welded rectangular steel pipe is usually carbon steel or low alloy steel. Common steel grades include Q235, Q345 in China, and corresponding international standards such as ASTM A500, ASTM A106.


Welded square tubes have high strength and rigidity due to their square cross-section and the characteristics of the materials used, which can withstand large loads and pressures.
