Do composite decking components come in different colours?

Yes, composite decking components are offered in a variety of colours. For instance, at Ecodek we’ve colour-matched the heads of our screws to the colours of our composite decking collections, for the most seamless finish.

What’s a Smart-Bit®?

The Smart-Bit® is a tool which allows the pre-drilling of deck boards. This means you can countersink our screws into the boards to give the most professional finish. More information about the Smart-Bit® is available on our screws and clips page.
