I don't know whether your aluminum alloy pavilion refers to the skeleton or the pavilion top material. If you use aluminum alloy as the pavilion, it may be "slim" because the aluminum alloy profile is not particularly thick.

The price of the pavilion made of aluminum alloy skeleton and galvanized colored tiles is for your reference: the price of a 3*3-meter four-corner pavilion is around 28,111.

I hope I can help you.
