Recycled plastic lumber is both practical and environmentally friendly, delivering excellent benefits to your project. Our recycled plastic lumber products are exceedingly durable, anti-rot and maintenance-free. 

Plastic lumber, unlike traditional timber, lasts far longer, does not split or splinter and does not require frequent treatment (i.e. sanding, staining and sealing), resulting in considerable lifetime cost savings by reducing maintenance and replacement budgets.

Plastic lumber is also incredibly versatile, being suitable for far more environments than wood. It can even be built directly into the ground due to its waterproof nature. This makes it the ideal material for areas subject to flooding or standing water.
