Co-Extrusion L Trim 3.66m - Teak

Give your decking the refined finish it deserves with this 3.66m Co-Extrusion L Trim in Teak. Designed to conceal cut board ends and protect exposed corners, it helps you create a smart, cohesive border around your composite deck. The warm Teak tone adds a natural timber look that pairs perfectly with matching Co-Extrusion Duo boards.

The trim is produced using advanced co-extrusion technology, featuring a tough outer shell over a composite core. This construction delivers excellent resistance to moisture, UV fading and everyday weathering, making it well suited to the British climate. It will not rot, splinter or warp like traditional timber, and there is no need for regular staining or sealing.

At 3.66m long with a 50mm x 50mm profile, this L Trim is easy to cut and simple to work with. Use it to finish steps, raised areas and the outside edges of your deck for a more professional look. The low-maintenance surface is easy to clean, so your edging stays looking fresh with minimal effort.

If you want a long-lasting, colour-matched finish that complements your composite decking, this Teak L Trim is the ideal choice. It helps tie your whole installation together while adding an extra layer of protection to vulnerable edges.

Start by checking that your decking boards are fully fixed and the outer edges are straight, clean and free from debris. Plan where each length of L Trim will be used so that joints fall in sensible places, such as corners or board breaks.

Measure the required length and mark the trim, then cut it using a fine-toothed saw suitable for composite materials. Offer the cut piece up to the deck to confirm a good fit before fixing it permanently.

You can secure the trim with either exterior-grade screws or a suitable outdoor adhesive. If you choose screws, pre-drill pilot holes at regular intervals along the trim to prevent splitting and to achieve a tidy finish. Fix through the vertical or horizontal faces into a solid substrate, keeping screw heads neat and consistent.

Around corners and steps, cut mitres or butt joints carefully so that adjoining pieces meet cleanly. Once all trims are installed, wipe away any dust or adhesive residue and give the edging a light clean. Your composite decking will now have a durable, Teak-coloured frame that enhances both appearance and longevity.
