Let me first start by saying that the product description here is completely incorrect. This gazebo is in no way built to be a permanent patio structure. It is more designed for temporary pop up purposes. It is not steel but more so aluminum and the top portion that holds the canopy is plastic. The canopy itself is made of the same material as a cheap bookbag or tarp. It does come with a traveling case bit it too is cheap (the handle on mine broke as soon as I took it out of the box). 

If you need something very temporary this might be okay, but even then Tim sure it would tear after a couple uses and putting up and down. Just not great quality. 

Went out to Lowe's and got a much better quality one for $50 more made by garden treasures.
