AR-DECK – Aluminium Decking

Aluminium Flooring with Aluminium Decking Joists & Adjustable Pedestals


AR-DECK from Alfresco Floors is a 100% aluminium decking system, comprising of deckboards with a fully adjustable pedestal and joist sub-frame. The patented pedestal has an in-built slope correction facility of up to 5% meaning that uneven groundworks or fall requirements are easily accommodated without the need for additional products. 


AR-DECK has been developed specifically to meet the requirements for non-combustible materials on balconies and other outdoor spaces, delivered at a competitive price and short lead times. 


Available in three standard colours, the non-slip deck boards can also be supplied to match any RAL colour, and with a life expectancy extending beyond 20 years,  AR-DECK offers a safe, hard-wearing, sustainable solution that will complement any scheme for many years to come. 

Non-Combustible Aluminium Decking 


Flooring materials that are intended for use on high rise buildings must earn a European Standard BS EN 13501-1 class A rating. This process considers the material’s ability to pass tests regarding its combustibility, burnability, and smoke ability. 

Aluminium decking is considered an A-rated flooring. The options available from Alfresco Flooring are considered A-2 rated due to the powder coating to improve its slip resistance.
