5 ways to prevent deck screws, joists, and fasteners from rotting or rusting

There’s nothing worse than discovering that the screws, joints, or fasteners on an outdoor structure are in poor condition and need to be replaced. Not only does this cost money, but it can drain your time and energy. We spoke to Rod Schiefelbein or Trex Company Australia for his tips and advice on reducing the risk of rust and rotting.

Insert screws carefully

“If you insert your screws too hard into wood, the beam can splinter at the source. The crack in the beam expands in the Australian elements, creating small “wells” for water to enter and sit in, causing corrosion on the screw. Avoid all of this by drilling a pilot hole to avoid cracking. “

Material match

“Be strategic with the fasteners and screws you will use during construction and choose materials that will work together and reduce corrosion. For example, do not use zinc screws to fasten stainless steel materials as they can weaken over time.


Stay dry

“Just as you don’t like being outside in the rain, neither do the beams on your deck. When wet, the joists and fasteners can warp and rust. Choose materials like galvanized steel or aluminum to reduce the chance of failure and place beams out of the rain if possible.

Prepare and protect

“The life of a structure is shortened when it is surrounded by damp, rotting wood – regardless of the screws and fasteners you use! Invest in a custom built one Deck Flashing Tape Protector, that’s a non-slip, Self-adhesive butyl tape to protect wooden joists and joists from moisture, which can lead to rot and loosening of deck screws and fasteners. “

Think what’s up

“If you plan to add potted plants to your deck, move them around regularly and never place them over screws or fasteners. This ensures that no wet spots form under the pots and trickle down to the metal. “
