Product Description
GD-011 Round Hollow Co-extrusion Composite Decking is made for outdoor decking projects that need a lighter profile without giving up surface durability. The round hollow core reduces board weight, making the decking easier to move, cut, and install across larger areas.
The capped co-extrusion surface gives the board better protection against moisture, stains, and daily weather exposure. For outdoor spaces that face sun, rain, and frequent use, it helps keep the decking cleaner and more stable than traditional timber.
Its woodgrain finish gives your project a natural decking look, while avoiding the regular sanding, painting, or sealing required by real wood. GD-011 is a practical choice when you need a low-maintenance decking board for gardens, terraces, walkways, poolside areas, or outdoor platforms.

Features
More Stable Color for Outdoor Projects
The capped co-extrusion layer helps protect the board surface from daily moisture, UV exposure, and repeated foot traffic, making it more suitable for commercial decking areas that need a cleaner, longer-lasting appearance.
Lighter Board, Easier Bulk Installation
The round hollow core reduces unnecessary material weight while keeping the profile practical for large-area installation. It helps contractors handle, cut, and install the boards more efficiently on terraces, walkways, and outdoor platforms.
Realistic Texture Without Heavy Maintenance
The deep woodgrain surface gives the decking a natural timber look, while the composite material avoids the regular sanding, staining, and sealing required by traditional wood. A practical option for distributors serving low-maintenance outdoor projects
