What are the box truss systems performaning in the stage system?

No matter what dimensions of your stage systems are, the Box Trussing Systems are requried as the bases for hanging lighting or speaker fixtures for actors and performances. And in many cases, the Aluminium Box Truss is performancing as a" silent behind scenes", since the audience often notices the lighting decoration, stage backdrops and performance of the actors on the stage.

The Lighting Box Truss features beautiful appearance which can be made into flat shape, round or arch shape, arbitrary curved shape, and it is convenient to produce and install. And it is good in stability and hight roof rigidity.

Why do we need the box trusses to build the stage?

The Box Trussing is a lattice structure composed of rods connected to each other at the ends. The trusses tubes are round and means that the rods in the structure are all circular rods. In most cases, the rods in the trusses only bear the axial tension or pressure, and the stress is evenly distributed on the cross section, so it is easy to play the role of material. These charactoristics make the truss structure economical and lightweight. Various shapes can be easily formed to suite different purposes, such as simply  supported trusses, arches, frames, and towers. Therefore, truss structures are used in many large-span stadium buildings, such as conference centers, stadiums, and other large buildings. It has been widely used in public buildings.

Most of the rods in the truss structure are connected by welding at the nodes. Before welding, it is necessary to cut the web bar and chord according to the welding shape of each electrod to be welded, which requires the web bar to perform intersecting line cutting and chord cutting. Since each member of the truss structure intersects with the member in the form of an intersection line, the cross-sectional shape of the end of the member is more complicated. Therefore, in the actural cutting process, two methods of mechanical automatic cutting and manual cutting are generally used.
