Insert screws carefully
“If you insert your screws into wood too forcefully it can cause the joist to split at the source. The crack in the joist will expand in the Australian elements, resulting in little ‘wells’ where water can enter and sit, causing corrosion on the screw. Avoid all of this by drilling a pilot hole to prevent cracks.”
Material match-up
“Be strategic about the fasteners and screws you use during construction, choosing materials that work together and reduce corrosion. For example, don’t use zinc screws to fasten stainless steel materials, as together, they can weaken over time.”
Stay dry
“Just as you don’t like being out in the rain, neither do the joists on your deck. When wet, joists and fasteners can warp and rust. Choose materials like galvanised steel or aluminium to reduce the chance of breakdown, and place joists out of the rain where possible.”
Prepare and protect
“The life of any structure will be shortened when surrounded by moistened, rotting wood – regardless of what screws and fasteners you use! Invest in a specially-made deck flashing tape protectant, which is a non-skid, self-adhesive butyl tape designed to protect wooden joists and beams from moisture that can lead to rot and the loosening of deck screws and fasteners.”
Consider what’s on top
“If you’re going to include pot-plants on your deck, move them around regularly and never place them over screws or fasteners. This will ensure wet patches don’t form underneath the pots and trickle down to the metal.”
