Whether the folding stage or the decent stage, which is the most used aluminum stage truss, which is the most excellent performance of
many of the truss products in a. But taking into account the aluminum itself is a more active metal costs, it is easy to react with the outside world of acid and alkali, so the protective
measures must be done in the round.
Aluminum alloy truss is a high strength aluminum 6061-T6, in order to improve the stability of the performance of aluminum alloy truss, the technical staff to enhance the ability to resist acid
and alkali. The used lighting truss is oxidized to make its surface with a layer of oxide film, which can prevent the
corrosion of aluminum alloy stage truss.
To overcome the defects of surface hardness and wear resistance of aluminum alloy, prolong service life, surface treatment technology has become one of the indispensable links in the use of
aluminum alloy. After the surface treatment, the metal oxide film is formed on the surface of the truss, which changes the surface state and performance, and improves its hardness and wear
resistance.
