Heres another site for similar ones in the UK

you get the idea...
The joints sure make is easy putting it all together however two thing to bear in mind..
1. They are not structural. So the load bearing and strength in mine comes from bracing it all together with the boards.
2. When they are in the joint they are pretty hard to pull out. I had to shorten a few of the lengths in the frame and when trying to get the connector out the broke off in the Aluminum.... a total pain in the *** to then cut, hammer and rip out. So I had to head back down to the store and get some more which just wasted time!
Over all though will definitely use a gain, the frame is so light and with the panels bolted on using hidden nuts its strong as you could want.
Used it a few times now and love it, best thing I have done to it...so far!
