Aluminum trusses are used more and more frequently and popularized with the development of performance in exhibition industry. The construction of stage trusses can better play the role of lighting and sound equipment and play a more ideal publicity effect.

　　The most important function for aluminum trusses or aluminum light frame is Loading capacity .

the entire performance process, all the lights of the audio equipment most suspension in  the truss, if the quality of aluminum truss itself has defects, or raw material composition is not up to standard, once more than bearing limits to stage collapsed, consequence is unimaginable.　　

So this paper discusses the basic factor that determines the quality of the truss, the raw material of the truss -- aluminum profile.

At present, national standard aluminum 6061-T6 is widely used in the manufacturing of aluminum truss in the industry. The national standard index of this aluminum material is mainly Wechler hardness HW and Brinell hardness HB, and corresponding 6061-T6 is 15-17 degrees Of Wechler hardness.Brinell hardness 80-110, the raw materials to meet the hardness standard is up to the standard. According to the sampling investigation of the manufacturers in Henan, Wuxi and Guangdong, where the production of aluminum truss stage and other performance equipment is concentrated nationwide, the conclusion is that all the manufacturers can basically meet this standard. The manufacturers in Henan and Wuxi all declare themselves to be 6061-T6 products, while most of the manufacturers in Guangdong use 6082 standard aluminum.

　　The results of this survey show that with the development of the performance industry, the corresponding aluminum  stage truss manufacturers have gradually matured, especially Guangdong manufacturers, regardless of the technology and material are further leading mainland manufacturers. This is great news for those in the performance and exhibition industries.
