What's the difference between the round pipe and the square pipe of the stage truss in the decoration industry?
Hello, the materials used in the stage truss of the decoration industry are the same as those used in the square tube truss, reaching the national standard. The square tube truss can be directly connected by screws when it is used, and the circular tube truss needs to be connected by the square head in the middle.
