A2 Fire-Rated Aluminium Decking
AR-Deck from Naturalis Limited 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.
Designed and manufactured in Britain, 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.
