Non Combustible Decking System Now Available

News & Case Studies

Non Combustible Decking System Now Available

Castle Aluminium Decking System is designed for both residential and commercial environments such as high-rise balconies, walkways, roof terraces, pubs, gardens and all other decking applications. Our aluminium decking, substructure and pedestals system is fully tested for fire resistance to EN 13501-1 meaning it can be used above 18m on high rise balconies. All parts of the system achieve Classifications of A1 and A2fl-s1. This independent testing satisfies current and proposed legal requirements.

Available in three colours with high slip resistance powder coated finish. Our anti-slip surface removes the traditional issues with mossy wet deck boards and the advanced design creates a heat resistant board, which is comfortable to walk on, even on hot days.

Key Features

  • Non combustible
  • Slip resistant
  • Hard wearing
  • Quick & easy installation

Our aluminium decking range is further complimented by adjustable pedestals. The patented pedestal is designed for use on inclines of up to 5 degrees, without the need for additional slope correction.

The pedestal is incredibly easy to adjust and can be slid along the beam to the desired position. The ease of installation and adjustment makes the Mextru pedestal a natural choice for the time conscious installer.

Designed to work exclusively with Castle aluminium decking joists.
