Ultra Deck Resist

Premium Performance & Looks

Ultra Deck Resist 150 is our premium decking board choice if you require a high specification or if your budget allows. It features our most beautiful surface ever and is designed to achieve the most natural wood look on the market.

This deck is produced via a co-extrusion process where a 360 degree outer armour is used to protect the core of the deck from the elements. As a result, Ultra Deck Resist is fire resistant to Class B, colour fade resistant, strength load resistant, stain resistant and also highly slip resistant.

It is available in 2 colours to suit all tastes, all of which feature a stunning deeply embossed woodgrain on one side and a light groove on the reverse for maximum versatility.

Ultra Deck is the ideal alternative to traditional wood, producing a longer lasting decking that is environmentally friendly, easy to install and requires minimal maintenance. Available in lengths of 3.66m, it is easy to install and has a fantastic 15 year warranty. Ultra Deck Resist never requires painting or treating and is easy to clean.

Why Dura Composites?
Dura Composites is a global supplier of fibreglass marina decking and composite timber pontoon decking as a replacement for traditional, older pontoon decking or deck materials such as wood and steel grating. Composite Marine Decking is ideal for many leisure developments as well as for refurbishment or upgrade projects across the marine industry.

Ultra Deck Resist Colours

Our Ultra Deck Resist decking boards are available in two stunning colours. Colour samples are available on request, or for large orders, additional bespoke colours can be requested.

Please note that colours shown are representative only; actual colours may vary slightly. Whilst Ultra Deck is relatively colour stable, there will likely be some initial colour lightening as the product weathers, which typically occurs in the first 3 months.

Our manufacturing process results in a high level of colour consistency although some variation in colour may be apparent across boards from different production batches.

6 Reasons To Choose Ultra Deck Resist


1. Resists Fire

Engineered to resist ignition of fire to BS EN 13501 Class B fl S1 to satisfy current and future fire legislation.


2. Resists Load

The Vortex Void design structure and unique material composition allows the deck to withstand 1.4kN point load according to BS 6399-1:1996 and to resist significant deformation or sag for its expected working life.


3. Resists Fade

Unique outer armour protects against fade for its entire life so that your deck always looks like it did when it was brand new.


4. Resists Stains

The revolutionary outer armour protects the deck surface from common stains from algae formation, to every day marine spillages. Just wipe immediately with a clean wet cloth to remove common spills or use a pressure washer for more stubborn debris such as bird mess.


5. Resists Expansion

The latest technology and cutting edge production techniques means that Resist features a rate of expansion that is less than half of its competitors. This means the deck will look great whether it’s hot or cold and is more forgiving on imperfect installs. This is due to the 360° Armour and the incredibly low water absorption rate achieved through a close cell structure.


6. Resists Slips

The fantastic wood effect surface features a unique finish that allows the product to achieve low slip potential in dry or wet conditions, whatever the direction of travel. When planning your deck, please note that other manufacturers use the irrelevant 5S slip test as their benchmark, which is easier to achieve and relates to roads, not walkways. We don’t!

Dura Composites’ innovative subsurface fixing systems means no nails or screws need to go through the deck itself, creating a smart, uniform and barefoot friendly deck. Our unrivalled range of fixings cater for a wide range of installations in different environments. Our expert team and downloadable Installation and Technical Manual can provide further guidance on appropriate use of these fixing solutions and screw types.


Step 1: Screw Start / Stop clip into suitable position ready to accept first board.


Step 2: Slide board into position.


Step 3: Position Fixing Clip into rebate at the side of the board and screw tight (6mm or 10mm).


Step 4: Slide next board into position making sure of a tight fit.


Step 4: Half Clips can be used for different to access areas. Double Clips can be used to fix across butt joints.


Step 5: Start / Stop Clip should be used to secure the final board into position.


Step 6: The Centre Clip is important for installs in extreme climates and where shading occurs and expansion gap consistency is aesthetically important.
