About Our Composite Decking

If you’re working on a garden upgrade, a raised platform, or a large commercial installation, all your composite decking needs are covered in our comprehensive range.

We stock industry-leading brands like NewTechWood and their Ultrashield (U-Shield) collection which is widely known to be a quality finish. They’re available in a variety of colours and wood-effect finishes to suit different design preferences.

All of our composite decking is made to be easy to install, with no need for regular sealing or staining like you would with traditional timber.

You will also find all your necessary accessories and fixings here like hidden fasteners and edging trims. Need pricing for a larger project? Use our quote form for a quick, no-obligation estimate.

Our Composite Decking Selection

Composite decking eliminates common timber issues such as warping and rotting, and it works especially well in high-traffic areas like porches, garden decking, and even on commercial spaces.

They require no painting, sanding, or sealing, and are ready for immediate use after construction. Choose your finish, your sizes, and create a space that works naturally into your landscape.

Our Composite Decking Board Sizes

Most of our composite decking boards are 23mm thick and 138mm wide, with lengths ranging from 2200mm to 4800mm depending on what you require.

These boards come in a variety of textured finishes and colours, with options including grey, brown, and black tones to match the surrounding environment or other landscaping materials.

The dimensions and surface finishes are engineered to deliver clean lines, uniform spacing, and a reliable long-term solution.

Buying Tip: Pair your decking with matching trims to achieve a clean, professional edge.
