With our vast coastline, Australia is a haven for recreational boating, sailing, and yachting, as well as to businesses offering fantastic facilities for boat storage, repair, and servicing.

As experts in the marine and leisure industry, we recognise that marinas and boatyards require regular maintenance and repairs due to their exposure to harsh environmental conditions and the heavy use they receive from boats and vessels.

Weather events can cause damage to docks, piers, breakwaters, and other structures, whilst the wood, metal, and concrete used in marinas are all susceptible to water-related damage, such as rot, rust, and erosion thanks to their constant exposure to water.

By staying proactive and following best practices for marina maintenance, operators in Australia and New Zealand can minimise the need for extensive repairs and ensure the safety and longevity of the facilities.

GRP (Glass-Reinforced Polymer) grating walkways are an excellent product for marinas due to their corrosion resistance, durability, excellent impact resistance and exceptional traction on walkways subject to tidal inclines, our grating is the right choice for your marine environment. And if protecting your precious marine life is important to you, our grating provides additional light transmittance to support all forms of life.


Tested to withstand even the wettest and oiliest conditions with high footfall


The load capacity is extremely high and provides excellent impact resistance


Ideal for waterside environments impacted by both mechanical and natural fluids

UV Resistant

Colour consistency and high performance even in the most extreme temperatures

For the best longevity, we recommend the use of GRP grating made from isophthalic resin – a type of polyester resin that is commonly used in marine applications due to its specific properties which include:

  • Excellent resistance to corrosion from exposure to saltwater to help protect the structural integrity of marine components, ensuring they remain durable and reliable. The resin is resistant to a variety of chemicals commonly encountered in marine environments, such as fuels, oils, and cleaning agents.
  • Low water absorption, meaning the GRP grating does not readily absorb moisture from the surrounding environment. This helps prevent the warping and weakening over time that’s so common with timber walkways.
  • Good resistance to ultraviolet (UV) radiation from sunlight. This UV resistance helps prevent degradation and colour fading of the composite materials, extending their lifespan.
  • Isophthalic resin can handle a wide range of temperatures and has high strength and stiffness. It’s mechanical properties make it ideal for constructing marine components that need to withstand harsh conditions including wave impacts and rough weather.

While isophthalic resin has many advantages for marine applications, you should ensure that the specific requirements of each project are considered when selecting your marina walkway materials as some applications might require even more specialised resins or composite materials to meet specific performance criteria. Most reputable suppliers should be able to provide up to date chemical resistance and datasheets to help you make an informed decision.

Streamline the process with our Modular GRP Fixed Jetty Kits.

These GRP Fixed Jetty Kits come with a range of benefits, the main one being its easy to set up design, which allows for a quick installation. This means that labour costs are decreased for the set up of the Jetty as it will take less time, combined with the kits being pre cut before they are sent out, meaning that you do not need to cut them yourself reducing the time from acquiring the product to installing it. Along with its lightweight design reducing the labour requirements for installing it as well, reducing both costs and time needed for installation.

Continuing on the theme of costs. The GRP Grating in these Jetty Kits mean that maintenance costs in the future is greatly decreased in comparison to traditional timber bearers, due to not being affected as heavily affected by harsh weather conditions/water erosion.

This combined with the environmentally friendly manufacturing for this product and with it being made with up to 50% less embodied carbon it demonstrates our dedication to creating sustainable solutions.

Discover the benefits of d2 Dura Grating

Designed, developed and manufactured by Dura Composites, d2 Dura Grating offers outstanding safety, performance and durability and is more cost-effective than traditional GRP grating in almost every scenario.

It can be applied in all industries where GRP mesh grating is used today and has an industry-leading Class Bfl-s1 fire rating as standard (in accordance with BS EN 13501). As with all our grating, it can be supplied with a range of stainless steel clips, clamps and hold down fixings to suit all install scenarios.
