Build your whole deck around our wood grain 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. Because wood grain grey is a mid grey, it works both ways in a two-tone design: pair it with light grey boards for a softer contrast, or add a border in anthracite grey or black composite boards to tie the deck to dark window and door frames. The calculator covers one colour, so add the second separately at the end.

Our Wood Grain Grey Decking Board combines the natural charm of timber with the practicality of modern engineering. Whether you’re creating a calming coffee nook or a space for summer entertaining, this board offers timeless style and top-tier performance.
Part of our Premier Collection, each board has a woodgrain texture on one side and grooves on the other for design flexibility. Lightweight, slip-resistant, and weatherproof, it’s easy to install and even easier to maintain, ideal for gardens that do more than just look good. For other lengths, colours, or styles, you can explore the full composite decking range.
We want your deck to have the perfect, lasting colour. Like all first-generation composite decking, this board will go through a natural weathering process where the colour will lighten slightly during the first few months of outdoor exposure.
To ensure it settles on its final, true grey shade, we have intentionally produced the board with a slightly darker tone. This expert process guarantees your deck achieves its intended beautiful colour and maintains it for years to come. We always recommend ordering a free sample to see the initial colour.

Expert Advice for Wood Grain Grey Composite Decking
Want to know more? Our in-house expert, Allan, gives his take on our Wood Grain 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 Grey wood grain decking has a very clever story. Through years of customer feedback, we know that most people are looking for that perfect ‘mid-grey’ tone. We also know that all composite boards go through a natural colour-settling process in the first few months.
So, we used that knowledge to our advantage. We intentionally designed our Grey boards to start as a slightly darker shade. This means that after they’ve settled in, they weather into the exact, mid-grey colour our customers are searching for. It’s a design that works with nature, not against it.
But that’s only half the story. The real innovation is the enhanced surface technology itself. After years of rigorous testing, we developed a surface that provides far superior, long-lasting colour retention and a richer, more authentic texture. It’s a solution born from customer feedback—an enhanced wood grain board like no other.”

Wood Grain Grey Decking Board Specifications
Check the Wood Grain Decking board’s dimensions below before you measure up, so steps, borders and any features in your design work out exactly. If you’re working the boards out by hand rather than with our calculator, An expert tip is: allow for the gap between boards: a 150 mm board needs a 3 mm side gap, so count each board as 150 + 3 mm across.

FAQ About Our Wood Grain Grey Composite Decking
1 Will the grey colour fade over time?
Yes, like all composite materials, our grey decking boards will experience a slight colour fade, around 15–20%, due to UV exposure. This natural weathering has been considered in the initial colouring and won’t spoil the aesthetic of your deck.
2 What's the difference between wood grain grey and grey composite decking?
Both are mid greys. Grey is our Home Choice grooved board, with a sanded finish and a wide groove one side and a narrow groove the other. Wood Grain Grey is the Premier board, with an embossed wood grain on one face and grooves on the other, so it has more surface texture and tonal variation. If you want a timber look, choose wood grain grey; if you want a flat, uniform grooved surface at a lower price, choose grey.
3 Can I install the wood grain composite boards myself?
Yes. These boards are designed with DIYers in mind. The grooved edges take a hidden fastener system, so installing your composite decking is a clean, professional-looking job without specialist tools.
4 Are the wood grain boards slippery when wet?
No. Both the wood grain and grooved surfaces are designed with slip resistance in mind, and the textured embossing improves grip in damp conditions.
5 How many wood grain grey boards will I need?
Use the quick calculator on this page: enter your deck’s length and width for a board count, and tick the 5% cutting margin to cover trimming and cuts. Each 3.6m board covers roughly 0.54 m².
6 Can I use these composite boards around a pool or hot tub?
Yes. The water-resistant nature of our composite decking makes it suitable for areas near pools and hot tubs. Just ensure proper subframe drainage to prevent water pooling beneath.
7 Are the wood grain boards suitable for heavy furniture?
Yes. The 22mm thick, four-core structure offers excellent strength underfoot, ideal for garden furniture and BBQs. Keep joist centres at 300mm (150–200mm under a hot tub) with proper framing support underneath.
8 Is the grey wood grain composite decking eco-friendly?
Yes. The boards are made from a mix of recycled wood fibres and plastics, helping to reduce landfill waste while giving a long-lasting outdoor surface.
