Rowhouse deck building - all allumimum and composite material

We are continuing the theme of material and technique experimentation at the rowhouse by incorporating a new deck system for the townhouse units.  This is interesting because it likely will either be a total disaster, such as the material does not withstand the temperature fluctuations, or a huge success, and the material will prove to be durable and moisture free for many years.  At this point I am still debating what is the more likely outcome.  

 

after much screwing around and redoing screwed up work, the structure begins to come together.  actually this is a photo of the  original screwed up version of the frame.

And the newly fixed frame is almost 'decked out' in the new composite boards.  looks good so far, but will it survive the harsh Calgary climate?  We will find out soon...
