Quad Truss

Aluminium quad truss is a four-tube square trussing system that offers clear spans of up to 18m. Quad truss will generally offer a higher load capacity than ladder or triangle truss system, also the square design eliminates the problem of apex orientation associated with tri systems.

Here at Stage Concepts, we have multiple variations of quad truss available, the three main systems of choice are our Deco Lightweight, SC Pro ST and Alustage ALC34. Each system offers its own unique benefits, the system we would recommend will depend on your requirements and specifications.

Lightweight Deco Truss

The smallest of our quad truss system, our deco truss offers a 220mm square with 35mm main tubes, 8mm braces with a 1.5mm wall thickness. Small and lightweight yet still extremely durable and strong. The deco truss provides 10m clear spans with up to 219.5kg of uniformly distributed load per meter. 

Due to its lightweight design, the deco truss system is an ideal solution for trade show and exhibition stands as well stage systems. The 220mm square design allows for easy transport and storage, while being our most cost-effective truss solution, generally more economical than tri truss systems.
