AliDeck Aluminium Decking Class B Board
The AliDeck Class B Balcony Decking Board is our original slip-resistant aluminium balcony decking product, offering unrivalled slip-prevention and B-Rated for fire safety. It has all the same product features as our other boards including quick installation times, a fully aluminium construction, and our 30-year warranty, but its B Fire Rating means it should only be used for ground-level decking projects.
These aluminium metal decking boards are treated with a special 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 an excellent fire rating and these are non-combustible except for the rubber slip-resistant insert which received a B Fire Rating.

|A2||Non-combustible/No contribution to fire|
|B||Very limited contribution to fire|
|C||Limited contribution to fire|
|D||Acceptable contribution to fire|
|E||Acceptable contribution to fire|

- The AliDeck Class B Balcony Decking Boards are constructed from aluminium and feature a rubber insert for slip-resistance, therefore making them a B Fire Rated decking solution. These aluminium decking boards are treated with a durable Qualicoat powder-coating to add colour to the boards.
Speed and ease of installation are key to any project, so we have designed a board that is easy to work with and fix to structures. 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 1200mm between joists on a 4kN loading.
The Class B Boards must be installed with a fall (recommended 1:80) for drainage.
Aesthetics are key to a great finish; our boards are designed to look like decking but not to feel like aluminium.
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 30% 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.
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.
AliDeck Aluminium Decking Installation Videos
No. If you wish to close the board ends you will need to purchase AliDeck End Plates when you place your order.
We strongly recommend that fixings are stainless steel grade A2 or A4. Fixings made from other materials such as nickel-plated brass or zinc are not advised.
We strongly recommend that clearance holes are pre-drilled in the decking board. This will help to ensure that the fixing will have minimal interaction with the aluminium and minimise the risk of galvanic corrosion.
We strongly recommend that impact drivers are not used to tighten fixings when installing our products. The use of impact drivers can over-drive the fixing and cause damage to the head, weakening or potentially breaking the fixing altogether.
When you are sure that stainless steel self-drilling screws are suitable for your application, we recommend the following;
- For steelwork less than 3mm thick, coarse-thread self-drilling screws should be used
- For steelwork greater in thickness than 3mm, fine-thread self-drilling screws should be used
It is essential that self-drilling screws with thermal washers are used. The rubber washer provides a thermal break between the screw and the decking board and reduces the risk of cross-contamination between steel and aluminium. Self-drilling screws with washers of the correct size to comfortably fit within the central fixing area of our decking boards are readily available.
Stainless steel self-drilling screws are able to be used to fix AliDeck products to steel framework. However, we strongly recommend that you understand precisely the specification and construction of the steel you are looking to fix AliDeck products to and choose the appropriate fixing to suit your specific situation.
We supply M8 bolts, nuts, and washers to fix our aluminium decking boards to our joists, but only when our boards and joists are purchased together as a decking system. We do not supply fixings when only our boards are purchased.
All AliDeck decking boards are available in stock lengths of 4m or 6m. We are also able to cut to length for a labour charge.

There are several ways that we can handle your order, as follows:
For large orders (minimum of 350KG per extrusion) we are able to arrange for custom extrusion to the precise quantity required. These extrusions are then coated and shipped direct to customers.
We hold a stock of uncoated, mill-finish decking boards and clips in 4m and 6m lengths, and joists and gutters in 6m lengths. These are then powder-coated according to order and are shipped to customer directly from our coating facility.
Cut To Length
We can cut extrusions to length for our customers. We do this at our warehouse in Rochester, Kent, and deliver from there. This service is subject to a labour charge, which varies according to quantity.

No. Galvanic corrosion can occur when aluminium and steel are in close proximity but all AliDeck decking boards are powder-coated on all faces to ensure the aluminium is protected.
