WPC Co-Extrusion Decking 148 × 22.5 mm (2.75 kg/m) — the wide-board option in our capped composite line. A polymer shell is co-extruded around the core in a single pass and fully bonded 360°, so it will not peel, delaminate or lift at the edges. The result is built-in weather resistance: UV-stable and fade-free, holding its factory colour after years in the sun; a dense, non-porous surface that repels coffee, sauce and oil stains — wipe once and it's clean, no staining, no mould; waterproof, scratch- and wear-resistant, with no painting, oiling or waxing ever needed. The 22.5 mm profile weighs just 2.75 kg per meter — solid underfoot yet light to handle, transport and install, ideal for rooftop terraces, balconies and poolside areas where weight and labour matter. And at 148 mm it is wider than standard 140 mm boards, so you need fewer boards and fewer joints for a more continuous, seamless-looking deck.
