The Federal™ and Grand Federal™ are designed and used in areas to take advantage of natural breeze with the saw tooth truss style. The Federal™ features a straight slope and the Grand Federal™ uses an arched shape to allow for the advantage of covering with either double layer poly film or polycarbonate panels. Used in combination with the SideWinder roll-up vents, SideWinder roll-up walls, or drop curtains, this is a great design to utilize natural air flows.


  • Roll formed stucture for superior strength
  • Built in condensaton removal channels
  • Coverable in corrugated polycarbonate, multilayered polycarbonate, double layer poly, and shade cloth
  • Easy expansion capabilities at gutter and length-wise
  • Aluminum finish trim and vents for sidewalls and gables
  • Standard clear span widths of 24 and 30 feet
