This steel tube is a sustainable and highly efficient option with a higher strength-to-weight ratio than wide-flange sections, giving your construction more support with a smaller,lighter-weight footprint.A square HSS steel tube column is a hollow structural section made of steel that is square in shape. It is made by welding twopieces of flat steel together along their edges. HSS steel tube columns are typically used in structural applications, such as
supporting buildings and other structures. They are also used to make fences, railings, and other metalwork. Square HSS tube are available to meet ASTM A500 or ASTM A1085 specifications. Square jumbo tubing is ideal for applications requiring uniform geometry along two or more cross-sections.
