Plaswood - Recycled Polythene

New products have entered the UK market, with Plaswood plastic lumber joints becoming increasingly popular. 

Plaswood manufactures its composite decking joists using recycled agricultural plastic. Plaswood is 100% recycled plastic and can be used in moist conditions or in water. The manufacturer quotes Plaswood as being 10 times more durable than timber in marine conditions.  

With our comprehensive selection of composite joists and accessories, you can confidently build and maintain your composite decking structures. Whether you're embarking on a DIY decking project or seeking supplies for a professional installation, we have the parts.
