Coastal Decking Range
Our Coastal Decking Range is engineered to withstand the extreme conditions of coastal environments.
Whether you're building a beachfront deck, a poolside patio, or a boardwalk near the sea, this decking delivers unmatched durability, resistance, and style.
Crafted using high-quality composite materials, the Coastal Decking Range resists saltwater corrosion, UV fading, moisture, and warping—making it an ideal choice for seaside applications. It offers a natural wood-like appearance while eliminating the need for regular staining, painting, or sealing.
Available in two elegant shades – Slate Grey and Ivory – this range adds a modern yet timeless appeal to outdoor spaces. These colors are carefully selected to complement the tranquil tones of coastal landscapes while offering a clean, sleek finish.
Each decking board comes in a practical size of 5400mm (length) x 180mm (width) x 23mm (thickness), providing a strong and stable surface with minimal joints and maximum coverage. The boards are slip-resistant, low-maintenance, and environmentally friendly.
Whether you’re renovating or starting fresh, the Coastal Decking Range combines performance and aesthetics to elevate your outdoor living experience.
