Similar to rectangular steel tubes, square tubes 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.
