This high impact strength composite decking board provides a durable alternative to traditional timber. It is manufactured from a robust composite material designed to withstand heavy footfall and harsh environmental conditions. The slate grey finish offers a contemporary aesthetic that suits modern landscaping projects. Because the surface is engineered for slip resistance, it is an ideal choice for homeowners or contractors who require a low-maintenance, safe walking surface that will not rot or splinter over time.
These boards are versatile enough for various applications across the UK. You can install them on garden patios, raised walkways, or as non-slip surfaces around swimming pool surrounds. They work well on commercial ramps where safety is a priority due to wet or icy conditions during the winter months. Whether you are refurbishing a small courtyard in a city centre or building a substantial deck in a rural garden, the slate grey colour provides a clean, professional look that complements most stone or brickwork.
Installation requires a sturdy subframe, typically constructed from treated timber or aluminium. You will need a drill and appropriate composite-specific screws to secure the boards firmly to the joists. It is essential to leave adequate expansion gaps between each board to allow for thermal movement during temperature changes. Before you begin, ensure the ground is level and the subframe is perfectly square. This preparation ensures a stable finish that prevents any warping or unevenness in the final layout.
The boards are available in two distinct lengths to suit different project scales. You can select the 1m x 140mm x 21mm option for smaller repairs or intricate borders. For larger decking areas, the 3.6m x 140mm x 21mm boards offer a more seamless finish with fewer joins. Every board maintains a consistent width of 140mm and a thickness of 21mm. The slate grey colour is integrated throughout the material to ensure the appearance remains uniform even after years of outdoor exposure.
Frequently asked questions
Can these boards be used for a ramp in a commercial setting?
Yes, the high impact strength and non-slip surface make them suitable for commercial ramps. They provide a reliable walking surface that can handle regular foot traffic while remaining easy to clean and maintain throughout the year.Do I need to stain or seal these composite boards?
No maintenance is required. Unlike timber, these composite boards do not need staining, oiling, or sealing to protect them from the British weather. This saves significant time and reduces long-term costs for the property owner.How do I prevent the boards from warping in summer?
You must follow the manufacturer's guidance regarding expansion gaps. Because composite materials expand and contract with heat, leaving specific spaces between the 140mm wide boards prevents buckling when the temperature rises during the summer months.Is the slate grey colour prone to fading?
The colour is part of the composite material itself. This means it is much more resistant to UV fading than traditional wood stains, ensuring your decking retains its dark grey appearance even after prolonged sun exposure.
