Global Truss F14 Square Truss LED wall infrastructure
LED wall modules are mostly not mounted directly onto the wall or ceiling but fixed to an intermediate support structure (a truss system, a wall bracket or a mobile stand), which has to safely bear its own weight as well as the load of the modules and cabling attached to it, and sometimes wind load too. The F14 is one of the smallest, lightest aluminium square truss profiles in the Global Truss range, typically used for smaller event technology suspensions with lower loads.
When sizing truss systems, the manufacturer gives a load capacity table for every profile as a function of span — the LED wall designer always has to compare this with the actual mass to be suspended (modules + cabling + any video wall processor); taking the truss type alone into account ("F-series square", for instance) is not enough.
Where the F14 Square Truss sits in an LED wall system
The truss stands between the cabinets holding the modules and the building (or the ground): the cabinets hang on it with lugs or clamps, and the truss in turn loads either a motorised hoist at the ceiling or supporting base plates. Besides the mass of the LED wall, the cabling, the power distribution box, sometimes the receiving card cabinet, and very often the lighting rigged above the wall hang on the same structure — all of these have to be added to the mass of the modules when sizing.
WHEN IT IS THE RIGHT CHOICE
On smaller, mobile or temporary event technology LED wall installations, where the mass to be suspended and the span do not call for a heavier, larger-section truss profile.
WHAT TO WATCH OUT FOR
A truss is only safe within the manufacturer's stated load capacity table — the actual mass of the LED wall, the cabling and the safety factor always have to be sized by a professional (a structural engineer or an experienced rigger), particularly on outdoor installations exposed to wind load.
The F14 Square Truss in practice
The manufacturer's load capacity table always refers to a given load case (a point load acting at the centre, an evenly distributed load, two supports) and has to be read together with the span: the figure given for a 4 metre span is only a fraction of that at 6 metres. On an LED wall the load is distributed but concentrates between the suspension points, so averaging is not enough. What the customer should ask for in the quotation: the installed mass of the wall in kilograms, the number and position of the suspension points, and outdoors a wind load calculation. In a hall or an arena the venue's rigging manager often also asks for structural documentation — this has to be obtained in advance, not on load-in day.
Alternatives to the F14 Square Truss
For a larger, heavier wall or a longer span, the F34 is the next step up, with an order of magnitude greater catalogue load capacity. On a fixed installation inside a building, a steel bracket frame fixed to the wall or a stand structure rising from the floor is often cheaper and more stable than truss. On a mobile wall rigged frequently, however, the truss's advantage is fast assembly and standard clamping. Deciding factors: mass, span, and whether the installation is fixed or demountable.
