The construction of various performance stages cannot lack trusses. At present, aluminum truss is more commonly used, and another iron truss is also used in many occasions. However, aluminum truss has its own unique properties compared to trusses made of other materials, which makes it the first choice for many large-scale performances. In summary, its advantages are mainly as follows.
Stage construction involves the transportation, handling and installation of trusses, while traditional iron trusses are relatively heavy, which brings a lot of inconvenience to various tasks. In contrast, the first-class aluminum truss is about half lighter than the iron truss, which also saves people a lot of cost and energy.
For those who need to set up a performance stage outdoors, people are most worried about the impact of direct sunlight and rain and snow on the quality of the truss. Iron trusses are prone to rust in a humid environment, while aluminum has relatively stable chemical properties and strong corrosion resistance. The best aluminum truss uses 6061-T6 aluminum alloy, and its longest life is more than 10 years.
To build a performance stage, it is indispensable to hang various performance equipment such as lighting and audio on the truss. These equipments themselves have a certain weight. For truss equipment with insufficient bearing capacity, it may not be able to bear these heavy objects. The best aluminum truss achieves its own balance through the reasonable arrangement of the upper and lower chords and webs, and the horizontal tension and compression internal forces. Its bearing capacity can reach more than 600 kilograms, which can fully meet the needs of the performance.
Aluminum truss is welded with high-strength aluminum alloy material 6061-T6 or 6082-T6. Because aluminum itself is a relatively active metal component, it is prone to chemical reactions with external acids and bases. If aluminum is in water for a long time, the aluminum component will also react chemically in the water. In order to provide the stability of aluminum truss performance, the technicians of the World Exhibition Group have improved the ability of acid and alkali resistance. The aluminum truss is oxidized to add an oxide film on the surface to prevent the corrosion of the aluminum truss from external substances.
In order to overcome the defects of aluminum alloy surface hardness and wear resistance, and prolong its service life, surface treatment technology has become an indispensable part of the use of aluminum alloy. The metal oxide film changes the surface state and properties, such as surface coloring, improving corrosion resistance, enhancing wear resistance and hardness, and protecting metal surfaces.
Aluminum truss is not only conducive to the stability of light positioning, but also can show different lighting effects. Aluminum truss, due to their aluminum alloy material, has a certain degree of sturdiness and stability during use. They will not easily fail or have problems, and will not cause damage to the built-in lamps. So when we choose aluminum truss products, if we want better protection of the lamps and make the structure products safer and more stable, then we must pay attention to the choice of materials.
Aluminum truss has complete specifications, and the cost price is not particularly expensive, so it is more and more popular. With the increasing number of aluminum truss manufacturers on the market, consumers need to carefully inspect these manufacturers and choose high-quality products, so as to maximize the advantages of the products themselves.
