Give your deck a crisp, modern frame with the Slate Grey Capped Square Edge Board — the ideal finishing piece for clean borders, picture-frame outlines, and secure stair treads.
Designed for contemporary outdoor spaces, this square-edge profile creates sharp, architectural lines that elevate the overall look of your decking. Its sophisticated Slate Grey colour offers a versatile, understated tone that pairs perfectly with both light and dark schemes, making it suitable for a wide range of design styles.
The board features a deep embossed woodgrain texture, replicating the natural feel of timber while delivering enhanced slip resistance for added safety on steps and high-traffic edges. The tactile finish not only looks authentic but also improves underfoot grip — especially valuable in wet UK weather.
Engineered with a durable co-extruded cap layer, this board provides outstanding protection against fading, staining, scuffs, moisture and everyday wear. The premium cap ensures the Slate Grey tone stays sharp, consistent, and low-maintenance, even under heavy use or prolonged sun exposure.
Installation is straightforward and tailored for a professional finish:
Use hidden clips on the grooved side to maintain a smooth, uninterrupted deck surface.
Secure the square edge with colour-matched screws for perfect alignment and a discreet, coordinated look.
This combination of hidden and face-fixing techniques creates a secure, stable border that resists movement and wear while maintaining a minimalist appearance.
Ideal for decking perimeters, picture-frame borders, stair fronts, and transitional edges, the Slate Grey Capped Square Edge Board offers the perfect balance of style, durability, and modern functionality. With minimal upkeep required — just occasional cleaning — it’s a long-lasting upgrade that keeps your deck looking freshly installed year after year.
