Product Description
The Oxford Woodgrain Series is our 4 m composite decking board: 4000 mm long, 146 mm wide and 25 mm thick, with an embossed woodgrain finish, in Black, Grey, Teak and Coffee. It is the most affordable decking in our range, and the long 4 m board means fewer butt joints across a wide garden deck. Stocked at our yard in Didcot, Oxfordshire.
- £40.00 per m² inc. VAT (1.82 boards at £22.00 per board; prices October 2026)
- 4000 × 146 × 25 mm · about 11 kg per board (2.75 kg per linear metre)
- Four colours: Black, Grey, Teak, Coffee
- 4 m bullnose step boards in the same four colours for steps and deck edges
Why choose a 4 m board?
On a deck up to 4 m deep, each run is a single board with no butt joint. On a deeper deck, fewer butt joints mean fewer double joists and a cleaner look. Check access before you order: a 4 m board needs a clear route from the road to the garden, and a vehicle that can carry it if you collect from our yard.
The four colours
- Black — a strong contrast against white or grey render and pale paving. Darker boards get warmer in full sun.
- Grey — a neutral mid-grey for modern houses, porcelain paving and anthracite window frames.
- Teak — a warm brown timber tone for red brick and planted gardens.
- Coffee — a darker brown for a traditional timber look.
