Benefits of Rectangular Tubing
Uniformity
In addition to its mechanical properties, Rectangular tubing contains uniform wall thickness and concentricity.
Strength
Cold forming allows square tubing to have a higher yield and tensile strength that the steel from which it is made. This makes the material able to withstand extreme temperatures, pressures and destructive elements.
Cost-Effectiveness
Rectangular tubing undergoes less processing that other types of mechanical tubing, so it can provide cost advantages for less-demanding applications.
Wide Range in Sizes
Rectangular tubing is available in an exceptionally broad range of OD and wall thickness dimensions. This makes it suitable to various applications and needs.
Applications of Square Tubing
Rectangular tubing is commonly used as a railing along staircases. However, it is also used in other, less obvious ways as well. From being used for fencing around yards to structures of buildings, as well as entry gates and entrances, a wide variety of applications are solved by steel Rectangular tubing.
