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.

SC Pro ST Quad Truss

SC Pro ST Square truss is manufactured here in the UK, and therefore of the highest quality. With a castellated 48mm tube and 1.6mm wall thickness, the SC pro TT will allow for a clear span of up to 12m.

SC Pro ST is our trussing system of choice for custom and bespoke projects. Being manufactured in the UK allows for a quick turnaround, especially on custom projects. We can design and fabricate any size or shape of structure and generally supply within two weeks. Options such as powder coating with a variety of finishes are also available upon request.

Alustage ALC34

Alustage ALC34 quad truss is our heaviest off the shelf system. The system 290c is a 287mm square truss constructed of a main tube of 48x3mm with 16x2mm braces and SZ04.04 connections. The heavy-duty design allows for clear spans of 18m with a uniformly distributed load of up to 903.8kg per meter.

The ALC34 is an attractive yet highly durable system that is an ideal solution for stage roofs, trade fair structures, exposition structures, big screen structures, LED display screen and projection screen support frames, lighting “gates” and sound “gates”, as well as frameworks for advertising banners or stage decorations.
