HSS (hollow structured sections) refers to a metal profile that is hollow and tubular. This hollow structural tube (or HSS) is used as a structural element in buildings, bridges and other structures, and in a wide variety of manufactured products. It's produced in round, square and rectangular shapes in a broad range of sizes and gauges.
HSS or hollow structural steel tubing has many benefits including:
ASTM A500 Tubing
Characteristics
ASTM A500 is a standard specification for cold-formed welded and seamless carbon steel structural tubing in round, square and rectangular shapes. ASTM A500 is the most common specification in North America for Hollow Structural Sections (HSS).
Applications
ASTM A500 applications include structural supports, building columns, highway signs, oil field services and communication towers.
