About Grainex®
The UK's premium composite outdoor living superstore.
Our Story
Composite living, done right
Grainex® was founded with a simple mission: to make premium composite decking, cladding and outdoor furniture accessible to every homeowner in the UK.
We partner exclusively with NeoTimber®, one of Europe's leading composite manufacturers, to bring you products that combine the natural beauty of wood with the durability and zero-maintenance convenience of modern composite technology.
Every product carries an industry-leading warranty of up to 25 years — because we believe outdoor living spaces should last a lifetime.
