New Jumbo HSS Sizes.
Now Available.


Dream Bigger with HSS

Hollow structural segments (HSS) give architects powerful tools to design taller, wider and bigger, supporting more weight while weighing less than comparable wide-flange sections. HSS’s distinctive rounded edges also offer great aesthetic possibilities for designs that make use of exposed structural steel.
