The clips allow the deck to expand or contract by about 5mm. 5mm Gap, allow a 5mm gap at the end of each board to expand and contract during hotter weather conditions.
Gradient allow for a 1 in 100 (1%) gradient to allow water to drain off the deck.

One of the greatest benefits of our Charcoal Grey Composite Decking is its low maintenance requirements. Unlike traditional wood decking, our composite decking is resistant to rot, warping, and splintering. It is also easy to clean and maintain, requiring only occasional cleaning to keep it looking like new.

Durable and Long-Lasting Performance

Our Charcoal Grey Composite Decking is built to last. Made from high-quality materials, it is resistant to the elements, including UV rays, moisture, and temperature changes. This means that it will retain its color and shape for many years to come, providing long-lasting performance that you can count on.

Please Note:

As with all brands of composite decking, SmartDeck’s range will lighten and lose up to 30% of its colour in the first 6 months before stabilising to its final colour.

Composite products are made in different batches. Batches can differ in size, shade, texture and colour. We highly recommend ordering all of your decking together to avoid subtle differences in appearance.

Composite Decking Boards have a width tolerance of up to 2%.
