4m ProDeck Composite Decking Board
4m ProDeck composite decking boards are a premium composite decking solution and provide high stain and fade resistance. ProDeck boards are available in seven multi-tonal colours to bring both durability and style to your outside space. With a detailed woodgrain effect on one side and narrow grooves on the reverse for enhanced slip resistance, ProDeck boards offer versatility and safety underfoot.
Explore Our Next-Generation Capped Composite Decking
ProDeck is an advanced capped composite decking solution, designed with a multi-tonal colour blend and a choice of two finishes. Featuring a dual-sided, capped composite core, ProDeck boards allow you to select either a low-slip surface or a natural woodgrain effect at the time of installation.
Each polymer-capped composite board is engineered with a weather-resistant surface, enhancing durability while offering excellent stain and UV fade resistance. These features help to minimise maintenance and extend the lifespan of your decking area.
Cladco ProDeck boards are constructed with a six-hole honeycomb composite core, ensuring they remain lightweight yet incredibly strong.

Key Benefits of Cladco Capped Composite Decking
- Exceptional durability: The capped protection layer shields the surface from moisture, mould, mildew, and rot, making ProDeck far more resilient than untreated timber.
- Low maintenance: No staining, sealing, or painting required - saving you both time and money.
- Reversible design: Choose between a woodgrain finish or a low-slip surface, with a variety of colour options to suit your style.
- Weather & UV resistance: Built to withstand rain, snow, extreme temperatures, and UV exposure, ensuring long-term performance in any climate.
- Splinter-free and safety underfoot: The capped outer layer ensures a smooth, splinter-free surface, making ProDeck safer than traditional wood decking.
- Eco-friendly composition: Each board features a strong honeycomb core, made from 60% FSC®-certified recycled hardwood fibres and 40% recycled plastics, ensuring sustainability with minimal replacements needed.

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.
