CHS Circular Steel Hollow Section
Steel HSS Tubes
CHS Circular Steel Hollow Section Description
Hollow Structural Sections (HSS) are often used in industrial building, construction, and infrastructure applications. HSS meets ASTM A500 or ASTM A1085 specifications to be used in the United States. 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.
As with square HSS, round steel HSS is ideal for creating uniform geometries. Round tubing is well-suited to constructing columns and features a high resistance to torsion.
