We are the UK’s longest established and largest WPC profile manufacturer, specialising in producing products that exactly match your needs – from a deck board cut to your specification to a completely new custom profile.

Our mission is to supply the highest quality wood polymer composite products.

Our core product is ecodek® – a recycled, durable, wood polymer composite decking board system, which is a sustainable, low maintenance alternative to timber that can be used in a wide range of construction applications in commercial projects and in the garden. ecodek® is available in two finishes, a reversible grooved/ribbed board and a new woodgrain effect board.

ecodek® is also available in two different substructure profiles (low profile & regular) that have been designed for use in supporting structures.

Our sales team is both knowledgeable and  helpful, so it doesn’t matter if you’re a home-owner looking for a new garden deck or a blue-chip company looking for a bespoke profile, you’ll always get our very best service.
