Product Information

Knife River produces Double Tee sections that range from 28″ to 36″ in depth with a 6′-0″ stem spacing typical.  Top flange width is 12′-0″ typical, but can be reduced down to 7-6″ depending on project requirements.

Standard Design Options

  • Double Tee end stems can be dapped (blockouts) at bearing locations reducing the beam/double tee framing depth.
  •  Double Tee flange depth is 2.5″ and will require a topping in most situations.
  • Double Tee stems can flanges can be used to hang utilities.
  • Stem blockouts can be inserted to run utility perpendicular to double tee stem
  • Optimize Gridline spacing 36′-0″ spacing
