Light Gauge Steel Structural Roof Systems

Do They Meet The BuildingCode?

On-line animated presentations:

Light Gauge Truss Structural Roof Systems!

  What is a "Structural Roof System"?

    A Light Gauge Steel Roof System consists of:

  • Light Gauge Steel Trusses

  • Truss Bracing

  • Truss Connections:

              Truss to Truss, Truss to Structure

  • Roof Deck Assembly

  • Shear Transfer Framing

  • Eave Edge Structural Supports

  • Valley, Hip, and Ridge Structural Supports

These 7 Structural Elements form a "Roof System"!


What is required to meet the code?

   The 7 structural elements of the "Roof System" must meet the

   following building code requirements:

  • Light Gauge Steel Trusses

  1. Support Vertical loads both up and down

  2. Transfer lateral loads

  3. Provide proper bearing for the deck i.e. avoid knife-edge conditions

  • Truss Bracing

  1. Prevent chord buckling

  2. Prevent web buckling

  • Truss Connections

  1. Resist gravity loads

  2. Resist wind loads

  3. Resist seismic loads

  • Roof Deck Assembly

  1. Support both uniform and concentrated vertical loads

  2. Act as a shear diaphragm resisting either seismic or wind loads


  • Shear Transfer Framing

         Collect shear and transfer it to the structure and the diaphragm chord



  • Eave Edge Structural Supports

  1. Support concentrated and uniform loads at the roof edge

  2. Collect shear from the roof deck


  • Valley, Hip and Ridge Structural Supports

  1. Support concentrated and uniform loads

  2. Transfer shear across the roof deck transition planes


         All 7 Items Must Meet Code Requirements!



 If each of these 7 elements in your light gauge steel

 roof system has not been designed and certified by a 

 structural engineer, then chances are:


Your Roof Won't Meet the Building Code!


  •  Our 7 elements will meet the building code

We guarantee it!

  • Our Roof System Will Work

We guarantee it!
