Aluminum truss is a kind of product you don't need to buy for decades when you buy it home. Why? Because the first aluminum alloy truss is corrosion-resistant, so there is no need to worry about rust. If you still think it's not safe, you can apply a little rust proof glue on the purchased aluminum alloy truss, so the service life will be longer.
Second, aluminum alloy trusses are not easy to break. Those easy to break on the market can be seen as defective goods. Aluminum alloy trusses are mainly used to hang lights, so they must be reliable in terms of bearing capacity.
Thirdly, aluminum alloy is easy to build. Apart from saving time and effort, the most important thing is that once a certain section is lost or damaged, you only need to find the manufacturer to buy a section instead of buying it all.
These three advantages make the quality of the aluminum alloy truss reliable, which also leads to the fact that it is not a one-time consumable. Therefore, it is reasonable that the aluminum alloy truss is expensive.
