A structural steel frame provides more useable floor space. 

A structural steel building provides more useable floor space because buildings framed in structural steel have smaller columns and longer spans than buildings framed in competing material.  The benefit is two-fold: greater design freedom for laying out floor plans and more useable space for occupants. The use of slender columns and lateral systems maximize useable floor space and long spans for open, column-free spaces.  The typical steel column occupies 75% less floor space than an equivalent concrete column. In addition, integration of HVAC systems into structural cavities allow taller interior spaces with more natural light.

Project Case Studies:

• Long-span transfers and signature cantilevered corner entries: New Irving Convention Center - Las Colinas, Texas
• Slim and elegant horizontal sway (drift) reducing system exposed on the facades:
  • 156 West Superior - Chicago, IL
  • LA Live - Los Angeles, CA
• Integrating the mechanical, electrical and plumbing with the structure proves advantageous:
  • Banner Bank Building - Boise, ID, A cellular beam project
  • North Carolina Wildlife Conservation Commission Headquarters and Exhibition Building - Raleigh, NC, Integrating structure and HVAC to increase ceiling heights can maximize natural light and help reduce building energy use.
