THIS PERGOLA IS AWESOME!!  I was a kind of nervous to begin because of the 4 boxes, and intricate design . We watched the 3-D video, very helpful,  and I was feeling a bit more confident.  It's really very well built.  Here in AZ we have wind!!  So we've attached it to pavers with cement under. It was a breeze to put together, my husband and I did most of it, but neighbors that stopped by were very happy to hold uprights while we screwed on the braces. We talked too much to say just how long it actually took us to put it together!!
I defiantly would recommend this white steel pergola!  It's not going anywhere...and will hold up nicely in the summer heat.  Thank You for such a great product with clear instructions
