LYSAGHT® SMARTRUSS™

LYSAGHT® SMARTRUSS™ is a roof truss system that offers durability, affordability, strength and stability. The system is convenient and cost effective, as well as quick and easy to deliver and assemble on
site.

LYSAGHT® SMARTRUSS™ system is manufactured from high tensile strength, long life TRUECORE® steel that is backed by a material warranty* of up to 50 years. It provides a lightweight alternative to timber roof framing and
is competitively priced as the system’s structural integrity leads to lower lifetime costs.

Engineered for strength, LYSAGHT® SMARTRUSS™ roof truss system does not compromise on safety and quality. It is subjected to comprehensive and rigorous testing processes conducted in Lysaght Technology’s world-class
National Association of Testing Authorities (NATA )-accredited structural testing laboratory. Full truss test rig and web compression, torsion bearing, and bottom chord tension tests are conducted to guarantee the system’s structural integrity.

APPLICATIONS
LYSAGHT® SMARTRUSS™ is a Fast, Efficient and Well-Engineered solution for general building applications in residential, commercial and institutional projects
• Fully designed and tested to Australian standards.
• Supported by LYSAGHT® SUPRACADD® detailing software which models the geometry, designs the roof trusses and facilitates fabrication by approved licensed fabricators.
*Warranty terms and conditions apply
• Will not warp, twist, shrink or rot, and no inherent weaknesses such as knots or cracks.
• Reduced builder call backs, no shrinkage, popping nails or rippled walls, ceiling or roofs.
• Termite and insect resistant.
• Fire resistant, non combustible.
• No roof sag, engineered pre-cambering ensures no wavy roof lines.
• Easy frame erection, lightweight and accurate frames are safe and easy to handle and fabricate on-site.
• Design flexibility as high strength to weight provides larger spans, fewer supports for traditional building methods.
• Additions for renovation purposes can be made after construction. Original steel structure will be straight and true regardless of age, and the job of lining up the extension
