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
