Hollow Structural Sections (HSS)

Steel Hollow Structural Sections (HSS) A500 / G40.21 50W/350W
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 has many benefits: aesthetic appeal, high strength-to-weight ratios, uniform strength, cost effectiveness and recyclability.

Resistant and Consistent

HSS is fire resistant and does not warp, twist, split, swell or shrink. It resists dry rot and mildew, termites and carpenter ants. For increased fire resistance, the exterior of the product may be sprayed with a fire retardant material, or boxed in with drywall. The interior can be filled with concrete.

Fabricator/Contractor Advantages

  • HSS can be readily bent, formed, punched, and drilled. New and improved methods to fasten HSS to itself or to other materials are making its use simpler and fabrication faster.
  • Easier, faster and cheaper to paint or coat (22.3% less surface area) 
  • Easier to weld in both the shop and field (due to restricted chemistries) no preheating or post-heating is required 
  • Easier to fit mating parts together (no notching or copying of joints as with beams or channels) 
  • Reduced weight means additional savings in erection and shipping costs

Architectural/Design Advantages

  • High quality surface finish 
  • Appearance in exposed applications can become an exciting and visual part of the design of buildings and other structures 
  • Cost effective in relation to other building materials 
  • Ability to conceal essential services

Engineering Advantages

  • Greater design properties in both axis (moment of inertia, section modulus and radius of gyration) 
  • High resistance to torsional loading 
  • Particularly suited for compression column applications 
  • Less weight-per-foot 
  • Diversity: strength, formability, toughness and corrosion resistance 
  • Less resistance to air and water flow
