Co-Extrusion Composite Flat Fencing 20.7cm x 1.8m - Anthracite

Create a stylish, low-maintenance fence with our Co-Extrusion Composite Flat Fencing Board in Anthracite. Designed to combine the appearance of timber with the durability of composite, this board is perfect for modern gardens, courtyards and commercial outdoor areas.

Each board measures approximately 20.7cm wide, 1.8m long and 2cm deep. The co-extruded outer layer features a realistic woodgrain effect and adds an extra level of weather protection, helping the board resist fading, warping and splintering over time. Unlike traditional timber, there is no need for regular staining or painting—just occasional cleaning to keep it looking fresh.

The Anthracite finish delivers a rich, contemporary grey tone that works especially well with light paving, rendered walls and minimalist garden designs. These boards can be used within a compatible composite fencing system to create full height panels, or as replacements for damaged slats in an existing fence.

Available across a six-colour range—Teak, Anthracite, Antique, Charcoal, Light Grey and Walnut—these boards give you the flexibility to create a coordinated fence that suits your space.

Whether you are building a full fence line or completing a repair, these Anthracite flat fencing boards offer a long-lasting, visually consistent solution with excellent performance in all seasons.

These composite flat fencing boards are typically used as part of a compatible post-and-rail or channel system. Always follow the specific installation guidance for your chosen fencing system, but the general process is as follows:

Prepare posts and supports
Install suitable fence posts and any required channels or rails according to the manufacturer’s instructions. Ensure all posts are plumb, aligned and securely set in concrete, with spacing matched to the board length (approximately 8m between posts for full boards).

Install bottom support or channel
Fit the bottom rail or channel between posts at the desired starting height. Check that it is level along the full run, as this will determine the appearance of the finished fence.

Position the first board
Place the first composite flat board into the system, ensuring it sits correctly in or on the bottom support. Confirm that it is level before continuing.

Stack or fix additional boards
Continue stacking or fixing boards one by one, following the recommended method for your fencing system (this may involve sliding into side channels or fixing with clips or brackets). Maintain consistent alignment and check for any gaps as you progress.

Fit top rail and finishing trims
Once the desired fence height is reached, install the top rail or capping piece to lock the boards in place. Add any supplied trims or finishing strips to conceal fixings and give a neat, professional appearance.

Final checks and care
Inspect the fence line to ensure all boards are secure, level and evenly spaced. Clean away any dust or debris with water and a soft brush. Ongoing maintenance is minimal—periodic cleaning is usually sufficient to keep the boards looking their best.

Always refer to the instructions provided with your specific fence system and adhere to local regulations and best practice when installing fencing.
