STI HSS Design Guides
Hollow structural sections (HSS) continue to surge in popularity due to benefits such as design versatility, high strength-to-weight ratio, and increasing availability. To ensure engineers, architects, fabricators and anyone involved in structural steel have a complete technical resource for using HSS, the Steel Tube Institute has created the HSS Design Manuals. The manuals are written by structural engineers for structural engineers and others active in the design and specification of HSS.
