Frequently Asked Questions

How does the cost of HSS compare to wide flange sections?

HSS is often more expensive than wide flange per pound.  However, in many applications, engineers can leverage HSS to achieve the same strength as wide flange while reducing weight as well as finishing and maintenance expenses. In the long run, opting for HSS lowers overall costs. Check out how much you can save on weight and cost with our free HSS vs. Wide Flange Comparison Tool.

What are the largest HSS sizes available?

Atlas Tube is the ONLY manufacturer in North America offering Made in USA Jumbo HSS. Our largest sizes are:  

  • Square HSS: 22” with wall thickness up to 1” 
  • Rectangular HSS: 34”x10” with wall thickness up to 1” 
  • Round HSS: 28” OD with wall thickness up to 1”

Is there a way to do field-bolted connections with HSS?

Yes! Traditionally, bolted connections to HSS have required access holes or attachments to the outside of the member. Fortunately, thanks to the Shuriken Structural Nut Keeper from Atlas Tube, many connections such as splices, shear, and moment connections can now be fieldbolted. Onesided connectors such as Hollo-Bolt and Blind Bolt can also be useful when designing field-bolted HSS connections.
