d2 GRP Heavy Duty Floor Grating

Designed, developed and manufactured by Dura Composites, d2 Dura Grating offers outstanding safety, performance and durability.

How does d2 Dura Grating differ from other Glass Reinforced Polymer (GRP) grating?

d2 Dura Grating can be applied in all industries where GRP mesh grating is used today and encapsulates a high strength to weight ratio, safe anti-slip surface and a unique patent-pending and design-registered design.


Designed resist corrosion, d2 Dura Grating is chemically resistant with excellent performance in extreme and hazardous weather conditions.

Fire Rating

Our proprietary d2 Dura Grating Standard Mesh is the first in the industry to be produced as Class B BS EN13501, superseding BS476.

Proven Anti-Slip

Our high spec surface materials are tested to 1.1 million footfalls (BS 7976-2), with ultra low slip potential and max durability.

Colour Fade

Use of hi-tech resin systems and application techniques means d2 Dura Grating’s colour is consistent and long lasting.

Mini Mesh Grating

d2 Dura Grating Mini Mesh has all the benefits of our d² Standard Mesh grating but with a smaller open mesh area depending on panel thickness. The smaller holes of this product prevent objects such as screws, nuts and bolts from falling through, and the aperture sizes comply with BS 4592 and the European 20mm Ball Falling Test.

The unique patent pending design allows for improved visual inspection of the substructure below. d² Dura Grating Mini Mesh is available in a 35mm, 45mm and 55mm thickness in Dark Grey, Yellow and Green. Also available in 23mm thickness with a 13mm hole size in Dark Grey and Sand. Patent Pending Patent Application No: GB 19 03941.1

Thickness: 23mm, 35mm, 45mm, 55mm
Hole size: 17mm, 19.5mm

Key Features:

  • Good Ventilation
  • Suits All Footwear
  • Meets 20mm Ball Test

Solid Top Grating

d2 Dura Grating Solid Top is a great choice for situations where no light transmittance, drainage or visual inspection of the area underneath the grating is required. The anti-slip properties and clever high spec gritted surface of d2 Dura Grating Solid Top provides higher opacity values than open mesh grating and the solid surface prevents all objects and debris from falling through. Available 29mm, 41mm and 53mm thickness in Dark Grey only. Other colours available by special order. Patent Pending Patent Application No GB 19 04928.7

Dura Composites’ Solid Top grating is lightweight with an extremely good anti-slip walking surface, suitable for wheeled trolleys or equipment often used in loading and storage areas. One of the key benefits of Solid Top fibreglass decking is the exceptional breaking strength under lateral force. The uni-directional continuous fibreglass reinforcement offers numerous advantages including rigidity, shock resistance, with no permanent deformation after overloading.

Thickness: 29mm, 41mm, 53mm

Key Features:

  • Max Load Bearing Strength
  • Suits All Footwear
  • Meets 20mm Ball Test

Micro Mesh Grating

Dura Composites Micro Mesh GRP grating features an anti-slip surface with a new finer grit which is ideal for water sports facilities and other recreational areas. The 10.5mm x 10.5mm open mesh prevents virtually all objects from falling through and is suitable for a wide range of footwear and sporting equipment. d2 Dura Grating Micro Mesh is available in Dark Grey as standard, with Sand and other colours available as special order. Minimum order quantities apply. If your project requires access ramps, 23mm Micro Mesh can be easily combined with other heavy grit products in the range.

We have exclusively designed a fixing to work seamlessly with the 23mm Micro Mesh. Our Micro Dome comes in a clever Dark Grey colour that blends into the dark grey grating seamlessly for that smooth finish if you’re looking to hide the fixings.

Thickness: 23mm

Key Features:

  • Good Ventilation
  • Suits All Footwear
  • Meets 20mm Ball Test

Our Most Advanced Anti-Slip Surface Ever: Tested to Over 1 million Footfalls

Dura Composites is committed to evolving our innovative product range to ensure that our customers experience unrivalled performance from their composite materials.

That’s why we’ve re-engineered d2 Dura Grating to deliver our best ever anti-slip surface.

Dura Composites’ unique high specification composition has been rigorously tested (in accordance with BS 7976-2:2002+A1:2013) and achieves ultra-low slip potential in both wet and dry conditions.

Not all tests are the same. We’ve invested heavily in ensuring that our test conditions simulate the effects of 3 months’ worth of pendulum testing, to assess the long term performance and durability of the Dura Composites products.

Under this recent testing, Dura Composites new d2 Dura Grating achieved an incredible score of 62 in the wet, (against the low slip threshold of just 36), making it ideal for almost all flooring conditions.

And what’s more, the low slip potential of the surface was proven to reduce by a mere 5% after an incredible 1.1 million footfalls, so you can have peace of mind in the safety of your heavy-duty flooring product for your specific application, whether it’s public sector or private sector.

Fire Safety: Designing out the Risk

Dura Composites is committed to helping ensure that you choose the most appropriate product for your specific fire safety project needs. Designing out the risk will ensure that your building project will safely comply with current and future building regulations.

BS EN 13501-1: 2018 Fire classification of construction products and building elements

d2 GRP Dura Grating flooring achieves a classification of Bfl s1, meaning very limited contribution to fire, with low smoke emissions.

BS EN 13501-1:2018 was published on 14th January 2019. It provides the reaction to fire classification procedure for all construction products, including products incorporated within building elements

The process for classification under this standard involves a combination of up to five rigorous tests designed to assess the product on a range of characteristics, including combustibility, heat levels, flame spread and smoke release. Once tested, the product receives an official classification of its fire rating, known as a Euroclass rating.

From best performing to worst performing, the Euroclass system is: A1, A2, B, C, D, E and F. It also provides additional classification (typically associated with reaction to fire classes D – B) for smoke production (from s1 (little or no smoke) to s3 (substantial smoke)) and flaming droplets/particles (from d0 (none) to d2 (quite a lot)).
