Several Common Styles of Aluminum Stage Truss

Time : 2022-09-19 Hits : 13

We often see wonderful stage performances on the street. You may not know the stage truss. In fact, the stage truss we see is composed of various parts and accessories, which are the basic conditions for stage construction. Among them, the truss acts as a support like the frame of the entire stage. It is to ensure the quality of the stage construction for the event and to ensure the safety of the performers.
Stage truss, also known as truss frame, stage frame, space frame. Stage trusses are generally made of aluminum alloys, but do you know the types of stage trusses?


At the first is the large variety of stage trusses, which are divided into the following two types by shape: Square Tube Truss and Round Tube Truss.
Square tube trusses generally have a section size of 20*20, usually 40cm, 60cm, 100cm and other specifications, and can also be spliced between different sizes according to the construction requirements, which can reduce the special size or In the case of insufficient supply, it is troublesome to go to another purchase.
The whole structure of the round tube truss is mainly a round tube with a wall thickness of 1.0, and the most important thing is that it needs square heads to connect. The size is not much different from that of the square tube. Generally speaking, the round tube truss is also better to be used indoors with the stage.


Followed by several specific types of stage construction trusses: triangular truss, trapezoidal truss, polygonal truss, hollow truss.
1. Triangular Truss
Triangular trusses are mostly used in roof trusses of tile roofs due to the large difference in the internal force of the chords and the unreasonable material consumption.


2. Trapezoid Truss
The upper and lower chords of the trapezoidal truss are parallel to the parallel chord truss. The stress of the members is slightly worse than that of the trapezoid, but the types of web members are greatly reduced, and they are mostly used in bridges and trestle bridges.
3. Empty truss
The axial force distribution of the members of the hollow truss is similar to that of the polygonal truss, but the bending moment at the end of the member varies greatly under asymmetric loads. The advantage is that there are fewer rods intersecting at the nodes, and the construction and manufacturing are convenient.
4. Polygon Truss
The polygonal truss has a uniform distribution of axial force on the upper and lower chords, a small axial force on the web, and the most economical materials. It is a truss form commonly used in engineering.
Before construction, the scale of the event and the expected number of participants should also be considered, and the specifications of the stage truss should be selected according to the effect of the event and the venue. The first is the site area. After selecting the stage area, choose the truss, the required span and load-bearing capacity, how much lighting, sound and other equipment need to be fixed, and where to fix it.


In a word,  It can be divided into single-row rack, tripod rack, square rack and folding rack. According to the different connection methods of trusses, there are bolt type, screw type and flat head type. The bolt type is more popular abroad, which is more convenient to install, and the screw type is more popular in China, which gives people the feeling of high safety factor, but the phenomenon of using the bolt frame is on the rise. Due to rising prices and various factors, people are more inclined to save labor costs and transportation costs.
Stage frame, truss frame, and space frame are relatively common terms for stage trusses, generally aluminum alloy profiles 6061-T6 and 6082-T6 (the material is better).
Many people think that screw racks are safer and more secure than bolt racks and flat head racks. In fact, there is no problem with the safety of racks.
