Aluminum alloy truss is also called truss, truss frame. General 6061-T6 aluminum through cutting, processing, welding, polishing, painting, is a widely used in performances, exhibitions, events, celebrations, background layout, lighting and sound suspension system. The truss system of various sizes can be built according to the site situation, and can be flexibly combined according to specific requirements. Light weight, easy to build and transport, the span can reach more than 30 meters, aluminum has strong pressure resistance, corrosion resistance and durability. According to the shape can be divided into square (corner) frame, tripod and special-shaped frame. According to the installation category can be divided into bolt truss and screw truss.

Aluminum alloy truss has wide application range, good performance, convenient disassembly and simple maintenance, making it widely used in various industries. Aluminum alloy truss is divided into aluminum alloy spiral truss and aluminum alloy truss in structure. At present, there are aluminum alloy truss performance companies, leasing companies generally buy aluminum alloy screw trusses. Spiral truss and quick-insert truss have advantages and disadvantages. Although the screw rack is troublesome to install and disassemble, it has good stability, high performance and strong carrying capacity, and is suitable for large-scale performances. The aluminum alloy truss has good appearance and simple installation. However, it is expensive to make, so the rent is also high. According to the shape of the truss, it can be divided into: the parallel string truss is convenient to arrange the double-layer structure; It is conducive to standardized production, but the distribution of rod force is not uniform enough. The folding string truss, such as the parabolic truss beam, has the same shape as the bending moment diagram of the simple supported beam under uniform load, the force distribution of the rod is uniform, the use of materials is economical, and the structure is complex. The stress distribution of triangular truss rod is more uneven, and the structure layout is difficult, but the inclined surface can meet the needs of roof drainage.
