Great work @blocks. Many thanks for sharing your project with us. You've been a member for many years now so it's also terrific to see you join in the discussions. The Bunnings Workshop community just loves decking projects so I'm sure they will be keen to hear more details about how you constructed the deck.
Thanks for posting a photo of your decking frame in its open form. It's really interesting to see how other decking frames are supported. It's also a great opportunity to inspect the condition of the frame and see if any of the parts need replacing. Those galvanized steel posts will definitely last a long time and in combination with the Ekodeck, you're looking at years of dependability.
