Purchased the decking using the online calculator I don't have enough material particularly not joists when installed at 300 mm. , I don't have any instructions for the installation of the joists. The decking joist screws purchased are at least 4 times as long as the composite joist is thick so unless you have a hammer drill and are fixing them to a concrete slab not sure how your supposed to use but then there are no instructions. Online installation guide displays a 404 page not found ***www.dreamdecking.co***/composite-decking/installation-guide. Super annoying..,,,
