This is a great Gazebo. I placed it on my deck in about 2 1/2 hours and that's assembling it all by myself with only some hand tools and a step ladder. The frame appears to be all powder coated aluminum and secured with galvaned nuts/bolts. I secured it to my deck using some 2 inch deck screws purchased from a local hardware store and it feel extremely secure. 
I'm anxious to see how it holds up during the heat of the summer and handles wind/rain storms but so far I couldn't be happier.
