Truss

From fabrication to installation, DuraPorts is committed to setting new standards in the industry.

Unique signature circle design in the truss offers exceptional aesthetic and marketing value

  • Simple, clean, upscale appearance
  • Marketing or branding opportunity

Dome-shaped cover, cantilever design and materials enhance its attractive appearance:

  • Minimal posts and hardware
  • Neatly hidden high-tension cable
  • Leading Cooltone Extrablock fabric from Alnet

Structural Design

architectural drawingCapacity: Two automobiles can be easily and safely parked underneath one unit

Dimensions of one unit are approximately:

  • 11 feet tall
  • 17 feet square (shade cover only)
  • 18 feet wide by 18 feet deep (including shade cover and footings), covering 324 square feet

Meets or exceed codes and requirements:

  • The Uniform Building Code based on the 2003 IBC requirements
  • Requirements of local and state building codes and authorities

Optimal Support: Design incorporates a “compression strut” which provides optimal support in extreme high-wind conditions

Structural Performance

DuraPorts are designed to withstand severe weather patterns, and to comply with local conditions and building codes. Our steel structures are backed by a 10-year warranty.

Engineering criteria includes:

Wind and Snow Loads (ASCE7-05)

  • Wind Speeds up to 130 miles per hour
  • Snow Loads up to 30 pounds per square feet which meets a large majority of snow load demands across the United States (See map below.)
