I purchased and set up a 10x13 aluminum gazebo with side curtains (can be seen on the Boscov's website). The aluminum legs twisted and fell within 2 weeks. The sides are completely useless and had to be tossed but the top and side curtains are still perfect. Any suggestions on how to build and secure the top I have? I am putting it on a stone patio and would like it to be structurally sound enough to keep up all summer and take down in the winter. Any ideas?? Thx!
