+ Composite Wood Image Gallery

Our gallery showcases a range of completed projects demonstrating the versatility and beauty of composite wood to help you envision how composite timber sleepers can enhance your outdoor space.


Composite timber sleepers are a sustainable and durable landscaping material made from recycled plastic and wood fibres. They offer the natural look and feel of timber sleepers without the maintenance and decay issues that come with natural wood. They are available in various sizes, colours and finishes, making them suitable for many outdoor projects.

They can be joined using either metal brackets or timber screws. Metal brackets are typically used for longer lengths or retaining walls, while timber screws are used for shorter lengths and garden edging. Pre-drilling is recommended before attaching the brackets or screws to ensure a secure hold.

They can be cut using a circular saw or handsaw with a fine-toothed blade. It is essential to wear protective gear, such as goggles and gloves when cutting composite timber sleepers. Before cutting, it is recommended to mark the cut line with a pencil and to clamp the sleeper securely to a stable work surface to prevent slipping.

Composite timber sleepers have a lifespan of approximately 20-25 years, depending on the quality of the product, installation and maintenance. Unlike natural timber, they do not rot, warp or splinter and are resistant to pests and insects.

They are also UV-resistant and do not require painting or staining, making them a low-maintenance option for outdoor projects. COEN has been offering a reliable range of composite sleeper products for over 15 years — and the quality we guarantee last twice as much.

They can be secured using timber screws or metal stakes. Timber screws are typically used for shorter lengths and garden edging, while metal stakes are used for longer lengths or retaining walls. Ensuring the sleepers are level and securely fastened is important to prevent movement or displacement.

Whipper snipper cords can cause damage to composite timber sleepers if used improperly. It is recommended to use a nylon cord with a 2-3mm diameter and to hold the whipper snipper at a safe distance from the sleepers. If the cord comes in contact with the sleepers, it may cause surface scratches or scuffs. Regular cleaning and maintenance can minimise damage and extend the lifespan of sleepers.
