4m Signature Solid Composite Decking Board
Cladco's 4m Signature solid composite decking board is a durable, high-quality alternative to traditional timber decking and is available in a choice of eight stylish composite colours. Adding composite decking to your garden is an excellent way to transform your outdoor space - especially in areas with high foot traffic or substantial outdoor furniture.
To qualify for our extended 15-year warranty, we recommend installing Signature composite decking boards onto a recycled plastic subframe, and in accordance with our installation guide.
Why choose our 4m solid composite decking boards
Thanks to its reversible, dual-sided design - with an authentic woodgrain effect on one side and low-slip narrow grooves on the other - you have the flexibility to choose the finish that best complements your outdoor space.
A popular choice for commercial and high-traffic environments, these solid-core boards deliver outstanding strength, structural integrity, and load-bearing capacity. Their enhanced sound absorption also makes them ideal for cafés, restaurants, terraces, and other public spaces.

- Length: 4m
- Width: 150mm
- Thickness: 25mm

Cladco 4m solid composite decking boards are made from a mix of recycled hardwood fibres and high-grade recycled plastics, bonding agents, additives, and tints. Part of our Signature range, these boards offer outstanding performance and come with a 15-year warranty for added peace of mind.
As part of the Signature range, we offer a complete selection of trims and fixings, including skirting trims, corner trims, fascia boards, and bullnose boards, to help you achieve a professional, cohesive finish.
For efficient installation and consistent spacing, particularly at butt joints, we recommend using T-clips. These fixings make installation easier and help ensure effective drainage between boards, reducing the risk of standing water. For a sleeker appearance, hidden clips are also available, allowing for tighter, less visible board gaps.
When compared to traditional timber decking boards, all of our composite decking boards require minimal maintenance and are easy to clean when necessary with the use of our ultimate decking cleaner. No staining, painting or varnishing is required to keep your composite decking looking its best for years to come. For long-term appearance and care, we also suggest using composite wood reviver to maintain your decking’s appearance.
Natural variations in colour and weathering are to be expected with composite decking due to its timber content. After installation, the boards will undergo a colour stabilisation process, influenced by factors such as sunlight exposure and local weather conditions.

For the most consistent results, we recommend ordering all your composite decking boards in a single purchase, as colours may vary between production batches. Even within the same batch, slight shade differences can occur. To help achieve a more blended appearance, lay out all boards prior to installation, identify any tonal variations, and mix them accordingly. Please also note that boards may appear different in wet and dry conditions.
*Cladco Composite products are available as FSC® certified at no additional cost. If you require FSC® certified products, please request this when placing your order.
Please note: Images are for illustration purposes only. Actual products may vary slightly from those shown.
Please note: All composite boards are manufactured with a tolerance of up to ±5mm in length and width due to the natural materials used and the manufacturing process. This is a standard industry allowance and does not affect performance once installed.

Customer Collection Notice
Please ensure you have pre-booked your collection slot before travelling to site.
When arriving to collect your order, please report to a member of our Warehouse Team who will register your arrival and locate your goods. Once ready, your items will be picked and brought to your vehicle loading area.
During busy periods, there may be a short wait while our yard team assist other customers or complete other loading tasks. We always do our best to work within your booked collection time.
We respectfully draw your attention to the following important points:
- Loading is ultimately the customer’s responsibility. While our team can assist with mechanical loading using forklifts, we cannot handball items into enclosed vehicles. Customers must ensure their vehicle is suitable and that goods are safely loaded and adequately secured before leaving the premises.
- Sharp sheeting, metal goods, and long/heavy items may pose additional handling risks. Please come prepared with high-quality protective gloves, and any appropriate protection materials to avoid damage to your vehicle or restraints (e.g. ropes or straps). The edges of roofing sheets and metal products can be extremely sharp, and care should be taken when handling.
- We strongly recommend that customers bring their own straps, ropes, or other securing materials, as we are unable to provide these at the point of collection.
- If you are unsure of your vehicle’s load capacity, we can advise the approximate weight of your order in advance. It is your responsibility to ensure your vehicle is suitable for transporting the goods safely and legally.
- Cladco will not be held liable for any damage to your vehicle or goods once they have been loaded and leave our premises. Loading assistance is provided entirely at the customer’s own risk.
Click & Collect – Pre-Booking Required
You are welcome to collect your order from either our Okehampton (Devon) or Andover (Hampshire) site. All collections must be pre-booked in advance so your items can be picked, packed and ready for you.
Please do not travel to site without a confirmed collection time, as we cannot guarantee your order will be available.
Once your items are ready, you will receive an email with a link to book your collection slot. Please note, same-day collections are not available and bookings must be made at least two hours in advance.
When you arrive, please bring your order confirmation and follow the signage to the collection area where a member of our team will assist you.
