Build your whole deck around our anthracite grey boards here. The calculator walks you through each part, from subframe and joists to clips, starter clips, fascia and edging trims. Enter your length and width in metres and skip any step for parts you already have. If you’re after a modern dark grey, our ash grey is the closest match and worth comparing before you decide.

The calculator covers one colour, so add any second colour separately at checkout.

Want to know more? Our in-house expert, Allan, gives his take on our Anthracite Grey Composite Decking, and we’ve selected some of our best guides to help you decide if this is the right choice for you.
A Word from Our Expert, Allan Jeffrey BSc. Eng. (Hons), Composite Materials Specialist, Environmentalist, and CEO of Ultra Decking:
Our Anthracite Grey is consistently a bestseller, and it’s easy to see why. It’s a versatile, contemporary shade that works with almost any garden design, and its dark tone is fantastic for hiding the daily marks and scuffs from kids, pets, and garden furniture.
But its popularity isn’t just about the colour; it’s also due to the advanced enhancements built into every single woodgrain board. We launched this enhanced surface after listening to customer feedback about fading issues on our older, first-generation composites. After years of rigorous testing, we developed a board with far superior colour retention and a richer, more authentic texture.
This means you get the contemporary Anthracite Grey style you want, with the proven, long-lasting performance our customers trust.

FAQ About Our Anthracite Grey Boards

No. The boards have a slip-resistant surface texture, making them safe for bare feet, pets and wet conditions.

Yes. With grooved edges and a hidden fastener system, installation is straightforward. If you’re comfortable with basic DIY tools, you can handle this project yourself; our installation guide walks through each step.
