AliDeck Aluminium Decking Junior Board

The AliDeck Senior Balcony Decking Board is our premium non-combustible aluminium deck board. It has been designed as a quick-fit solution for easy installation, delivers excellent span of up to 600mm to comply with BS8579:2020 (2.0kN point load with maximum allowable deflection of 5mm), has a fully aluminium construction, is fire resistant, and comes with our 30-year warranty.

AliDeck aluminium metal decking boards are treated with a special Qualicoat powder-coating process which colours the boards in a choice of our full range of AliDeck colours. This finish along with the aluminium construction gives the boards fire ratings of A2-s1, d0 and A2fl-s1 which means they are non-combustible, provide no contribution to fire, and are fully compliant with all relevant regulations and legislation.

Speed and ease of installation are key to any project, so we have designed a board that has a unique invisible (structural) top clip system which can be installed from the top down. The board can also be trimmed down the length to match any projection of balcony and still be structurally stable across the whole plank. The boards can be cut to size along both the length and width.

The AliDeck Aluminium decking boards are 50% quicker to install compared to other decking systems on the market. These boards are fixed from the top down so requires no fancy, fiddly fixings. It can also span 600mm between joists on a 2.0kN loading (BS8579:2020).

They can also be spaced to allow for varying drainage requirements (unlike any other system).

Aesthetics are key to a great finish; our boards are designed to look like decking but not to feel like aluminium.

Colour Options
The decking boards are available in the full AliDeck range of Qualicoat powder-coat colours.

All AliDeck aluminium decking boards are fully compatible with all AliDeck Joists.

The boards are constructed completely from 100% aluminium (6063 T6 grade), up to 67% of which has been recycled to make these boards eco-friendly and much better for the environment.

Due to the fact that AliDeck is aluminium and finished using the 5 stage Qualicoat system, little or no maintenance is required. General grime can be removed simply with a damp, lint free cloth or mop with warm soapy water.

Protective Finish
The planks are coloured using the Qualicoat powder coating finish. Qualicoat is a quality label organisation committed to maintaining and promoting the quality of coating on aluminium and its alloys for architectural applications.

The decking is supplied with a 30 year warranty against splitting, cracking, warping, splintering, rotting, twisting and material or manufacturing defects. It has a minimum 60 year life expectancy.
