Layer truss was invented by Layher in Germany. It is also called "layer truss" by people in the industry, also known as net pulling and net pressing frame. It has different names in different places. It is mainly used for the lighting frame and background frame of large-scale concerts. It has the advantages of simple installation and disassembly, not easy to lose accessories and good stability. It is widely used in the fields of architecture, stage background, lighting frame and so on.
According to ordinary people, aluminum truss and Layer are not the same. What's the difference? In fact, ordinary people don't often use these two trusses, so they don't know the difference between them. Many people have never seen them before, they just talk about them.
People who have really used aluminum alloy truss know that aluminum truss has no problem for small and medium-sized performance, but for some large-scale performance, it is obviously unreasonable to use aluminum alloy truss hanging lamp. Why? Because there are too many shelves for large-scale performances. At this time, it is necessary to use the Layer frame. The Layer truss is easy to build and strong. A disc, a connector, a bolt and a column can be perfectly supported. It is not only a large-scale performance, including things to be put in the warehouse, but also a Layer frame can be perfectly supported. This bayonet is similar to the wedge structure of Chinese carpenters.
Compared with aluminum alloy truss, layer truss frame is mainly used for hanging linear array sound and chandeliers, while aluminum alloy truss (also known as aluminum lighting truss) is mainly used for hanging lamps or building large tents. At the same time, compared with aluminum alloy truss, the load of Layer frame is greater. After all, it is composed of an iron pipe, and aluminum alloy is lighter.
From the article, we can see how intensive the layer frame is for large-scale performance. Aluminum alloy trusses are different from Leia frame structure, so they have their own characteristics and become different types.
Which System Should You Choose?
Both aluminum truss systems and steel Ringlock (Layher-style) structures play important roles in the event industry, but they are designed for different applications.
Generally speaking:
Aluminum Truss is ideal for lighting grids, stage roofs, exhibition structures, entrance arches, and portable event systems where lightweight construction and rapid installation are important.
Steel Ringlock Structures are better suited for heavy-duty applications such as FOH platforms, grandstands, camera platforms, large stage substructures, delay towers, and other projects requiring high load capacity and exceptional stability.
Many large outdoor concerts combine both systems, using Ringlock structures as the primary support framework while aluminum trusses carry lighting, LED screens, and audio equipment.
Selecting the right system depends on structural requirements, equipment loads, installation conditions, and project budget.
