Rectangular steel tubes sold by CamaSteel are commonly used in welding steel frames where locations on the frame that are experiencing multiple directions of load are supported. These steel tubes are strong, tough, and durable. They can either be 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.
