The latest in wood polymer composite technology

Composite decking boards provide a long-lasting, anti corrosive and slip resisitant platform that will make any external area beautiful- a serious alternative to traditional treated timber decking. Available in 3.6m lengths (146x25mm section) with heavy-duty internal ribbing to provide a durable and strong board. For composite decking in Liverpool or the North West give us a call.


Maintenance Free

Unlike traditional timber, HD Deck requires no staining, treating or painting. Due to the expensive UV inhibitors, the product will maintain its good looks years after installation.

Long life

Due to HD Deck’s low water absorption rate, fungal and rotting problems associated with traditional timber decking are now a thing of the past.

Barefoot Safe

HD Deck is not only comfortable to walk on barefoot, it’s also safe to do so because of its naturally splinter free properties!

Environmentally Friendly

Composite Prime is committed to the environment. HD Deck exclusively uses 100% FSC wood from well-managed sustainable sources that can be traced back to its origin, and recycled plastic.
