Box truss are used in the construction of concert and theatre stages, designed to make the stage extremely strong and able to bear heavy loads that enable the stage to support various types of props and equipment that will be used during the performance. Also called a stage truss, the box truss has many other uses in addition to concert stages. These include electric power pylons, bridges, radio antennas and even in the fuselage of aircraft. The reason they are so popular is due to their design. Basically, a box truss is constructed of three chords (or more), which are supported by diagonal structural elements in order to increase their strength. The box truss is able to support far greater loads than what a concert stage without trusses would be able to, thanks to its diagonal supports. They are also more resistant to twisting, buckling and swaying in heavy winds. There are many different kinds of box truss materials available. One of the most common is the aluminium truss, as this kind of stage truss is lightweight (and so easier to put together) and relatively cheap, yet still able to support very heavy loads. Different load-bearing capabilities are often used to define a box truss. The 12x12 truss is the standard for a medium-duty truss, although larger sizes are available for a heavy duty truss. Itâ??s also possible to find smaller, light-duty truss sizes.
