Our Service


Hyperion Decking products will provide years of outdoor living pleasure with the proper installation.

For the full downloadable Hyperion Decking installation guide, technical specifications and slip test results, please click here.

While Hyperion Decking composites are highly durable, to ensure the lasting beauty of the decking products, please follow these important handling and care guidelines.

Please note that with the Pioneer range there will be initial lightening as the product naturally weathers over the first 8-10 weeks including a reduction in the wood grain due to tannins (wood oils) leaching out of the board, after which they are relatively colour stable. To find out more about tannins and to see how your boards will fade, please click here.
