Composite Decking

Elevate your outdoor living areas with high-quality composite decking from Castle Composites Ltd, combining outstanding durability with low maintenance and exceptional aesthetic appeal. Whether you’re creating a stylish patio, garden terrace, or poolside deck, our range of composite boards delivers long-lasting performance without the typical upkeep of traditional timber.

Choose from a variety of stunning finishes to suit any design vision, including salt lake silver composite decking for a light, contemporary look; ancient black composite decking for bold, modern contrast; wild brown composite decking for warm, natural tones; and antique ash composite decking for subtle sophistication. Each board is engineered to resist fading, staining, and moisture, making them perfect for busy outdoor environments and all-year-round use.

As a trusted composite board company, Castle Composites offers products that outperform many alternatives, including rubber decking boards where increased slip resistance and comfort underfoot are preferred.

Impeccable service from this company! From start to finish they have showed patience, kindness and honesty throughout. As for the product.......beyond our expectations!! After almost a year of deliberation and with limited options due to placement we decided on the grassflex tiles and 100% made the right choice. Great quality! Thank you

Absolutely amazing customer service from Fraser Brown! We had a delivery of outdoor tiles this morning, and our construction team was struggling to figure out how to use the levelling discs supplied. Fraser immediately stepped in and provided a direct WhatsApp number so the team could send videos and speak to him directly. The issue was resolved within five minutes. A huge thank you to Fraser for such responsive and hands-on support — truly appreciated!

A great experience with Castle Composites! We purchased the EPDM Rubber Tiles in ‘Sunburst’ for the kids’ play area section of our garden. Fraser was a wonderful help - from the first phone call enquiring about the product, showing us samples at the warehouse, liaising throughout the ordering and production process (and for helping with a later change to increase our order quantity within the same batch), to ensuring smooth delivery, Fraser’s customer service was fantastic and very much appreciated. The play area is now fully installed in our garden and we are delighted with the finished product. Thank you!

Excellent service from a great company with fantastic staff and a wonderful product. We have just used Castleflex tiles for our large patio and are very pleased with the end result. They look great and were easy to lay.
