Learning Objectives
Upon Completion of this course the Design Professional will be
able to:
• Explain why Light Gauge Steel Trusses are a Good Alternative
Solution
• Explain applications for Proprietary LGST
• List and describe Case Studies
• Specify LGST
• Describe the design process for Factory-built LGST
• Explain: Fabrication, Packaging, Shipping, & Installation of
Factory-built LGST
• Compare and contrast an LGST proposals and explain what
makes a complete truss system
Why Light Gauge Steel Trusses?
Wherever steep sloped, residential-style
roofs are desired…
AND
Non-combustibility is mandated…
The IDEAL solution is...
Light Gauge Steel Trusses
The Advantages
Advantages Are:
1. 100% non-combustible
2. Long clear-span capabilities
A. LGSTs can typically span 80+ feet, depending on loading
criteria.
B. Obviously, spans will vary greatly between snowy regions such
as New England and warmer climates like Texas.
3. Limitless roof and ceiling profiles--just like wood trusses
A. Engineers hate to hear this, but with the computer software
available today, designs can be more dynamic than ever.
4. Lightweight
A. LGSTs are typically half the weight of wood trusses due to their
high strength to weight ratio.
B. This is an advantage for long spans and heavy concentrated
loads since the trusses are not having to work double duty to
support themselves as well as the loads being applied.
The Advantages
5. Pre-engineered and pre-fabricated by truss professionals
A. Proprietary trusses are designed by experts, and sealed by
veterans in the light gauge truss business.
6. Eliminate attic sprinkling systems
A. Often sprinklers can be downsized or even eliminated when
the roof structure is built from completely non-combustible
materials. There is nothing to burn!
7. Compatible with almost any decking/roofing system
A. There are fastening methods that can effectively handle
connections to everything from plywood and metal deck to
unique materials like Structural Insulated Panels or SIPs.
8. Relieves design firms of costly, time consuming roof design work--
frees them up for more productive endeavors
A. Because the design software handles the engineering, sizing
of materials and calculation of loads, architects and
engineers can simply specify that LGSTs be used, provide the
basic design criteria and profiles. The truss designer can take
it from there.
LGST are an ideal substitute for…
Bar Joists
Concrete Red Iron
Fire
Retardant
