New Zealand International

Our innovation in deck design and construction methodology has not only driven us to release world class products that help the builder create safer and stronger deck structures, but it has also lead us to develop a market leading decking screw range to be enjoyed by both the builder and the home owner alike.

Gone are the days when home owners put up with nails that pulled up or squeaked in a deck that has become an extension of their home.

The next evolution in that development is now here, with the introduction of the ultimate Self Drilling Decking screw - the DSD. The DSD range is available in 5.5mm (12g) and 6.5mm (14g) diameter, with lengths from 50mm through to 100mm, collated for Quik Drive, as well as loose.
