Square Steel Tube History and Benefits

Similar to rectangular steel tubes, square tubes from the top Chinese steel producers sold by CamaSteel undergo the same process of either being welded or seamless where in the past seamless tubes were much stronger. However, technology has advanced enough to eliminate this difference. Steel tubing can be used in both domestic and industrial settings because of their ability to withstand extreme temperatures, pressure, and natural destructive elements. In a domestic scenario, these steel tubes can be used to transport gasses and liquids. When considering rectangular or square tubes, it is good to know that square tubes are stronger but weigh and cost more than their rectangular counterpart. Another benefit includes uniformity in wall thickness and concentricity.

Production of CamaSteel’s Square Steel Tubing

Square steel tubes begin their life as iron ores that are melted into a liquid substance that are cooled into ingots. These ingots are flattened through steel rollers that make them into slabs of steel with rectangular cross-sections and cut into the necessary shape. These welded pipes that were formed from a roller system undergo an electric-resistance welding process which forces and binds the slabs together to produce the tubing.
