F45 Truss is the most popular size of the 5-Chord Truss family at 400mm x 400mm with 50mmØ x 4mm chords. The fifth chord addition was specially designed to assist in the centring of the suspended load, always a challenge on Square Truss with two bottom chords. It is particularly focused on the suspension of larger LED screens where a long, continuous load must be centred with very little or no deflection. The fifth chord is also ideal for suspension of drapes, dividing walls or set pieces. Of course, F45 5-Chord Truss can also be used for more general truss applications where you can make use of all three bottom chords. Two engineering load tables are provided with all Global Truss 5-Chord Trusses. One table has a standard deflection limitation of 1 : 100, and the second a 1 : 300 deflection limitation, which is more applicable for the suspension of LED screens.
