Beauty that lasts: nail-free decking

“The system utilizes DNA certified kiln dried Kwila boards which are pre-oiled and pre-grooved, and is fixed with hidden UV nylon side fasteners that slot into the timber grooves. The side fasteners are secured with high quality German Spax screws at a 40 degree angle that allows for a much stronger system than face fixing. Most importantly – without rows of nails or screws visible on the deck surface, you get a beautiful, unbeatable finish every time” Shadow Deck’s Darrel Grace says.

“With face fixing, you’ve only got the holding power of a four to five mm screw or nail, which is significantly less than with this system. Because the nail free system requires the screws to be fastened at a 40 degree angle, the water isn’t able to run down the screw and penetrate the wood either, which while making it stronger also makes it much more durable over time.”
The fasteners are made with a UV nylon and slot easily into the side of the pre-grooved boards creating a perfect 3mm gap between boards.

The pre-oiled Kwila decking boards also have a domed profile to help shed water. From the centre of each board there is a 2mm fall to the outside edges.  “They’re coated with a specialised oil. Each board goes through my oiling machine which means the entire board is penetrated, unlike many other products. This along with the domed profile further increases durability, stabilizes the deck and prevents cupping” Darrel says.

Nail free timber decking systems have now been chosen by thousands of New Zealand property owners to create aesthetically superior outdoor living spaces, with clean, contemporary lines that will last longer than traditional decking.
