Exploring the Versatile Applications of Glass Reinforced Plastic (GRP) Grating

Well-made plastic grating is a versatile material that finds its applications in myriad industries and settings. Read on as we delve into how Glass Reinforced Plastic (GRP) grating can be used across many industries and use cases.

What is Glass Reinforced Plastic Grating?

When we talk about plastic grating or glass reinforced plastic (GRP) grating, we mean a structural material composed of synthetic polymers or plastics characterised by a grid-like pattern. Each product is made with different types of plastics and designed for different purposes. 

In plastic grating production, there are essentially six different approaches, and each has slightly different properties:

• Moulded Glass Reinforced Plastic (GRP) Grating is manufactured by combining plastic resin and glass fibres in different ratios to achieve different strength levels while being corrosion resistant.

• Pultruded GRP Grating is created by pulling continuous glass fibres through a resin bath and then through a shaping die. It tends to offer excellent load-bearing capabilities.

• Moulded High-Density Polyethylene (HDPE) Grating is made from high-density polyethylene and is sometimes used in less demanding applications.

• Pultruded Polypropylene (PP) Grating, similar to pultruded GRP grating, is made using polypropylene fibres and resin. It offers good chemical resistance and mechanical strength.

• Vinyl Ester Grating can be used in the production of GRP grating, providing enhanced resistance to corrosion and chemicals.

• Expanded Metal Grating, although not entirely plastic, can be coated with a plastic layer, such as PVC or polypropylene, to provide additional durability.

GRP grating often provides advantages over other plastic alternatives and traditional materials like steel, aluminium, and wood. These benefits include:

• Exceptional durability, with a high strength-to-weight ratio that, depending on the specific material, can even carry vehicular loads while weighing less than steel

• Corrosion resistance to reduce maintenance requirements

• Resistance to chemicals for demanding industrial environments 

• Non-conductive properties, making it a safer choice than metal for electrical environments

• Industrial Flooring and Walkways or Catwalks

  GRP grating plays a pivotal role in industrial settings, providing robust flooring and walkway solutions. There are even types of GRP grating that offer a slip-resistant surface and are manufactured to ensure longevity in harsh chemical environments. At CXY Chemicals in Domino, Texas, for example, Fibergrate GRP grating was installed for a spill containment area where chemicals are unloaded.

• Drainage Systems

  Efficient water flow and the prevention of slip hazards are paramount in industrial areas. Plastic grating excels in both aspects, offering excellent drainage while enhancing worker safety.

• Staircases and Platforms

  In industrial settings, staircases and platforms require high durability and strength. GRP grating delivers these attributes and, importantly, its non-conductive nature ensures electrical safety in hazardous environments.

In these spaces, the requirements for safety and durability can be especially challenging to meet. Glass Reinforced Plastic grating meets those challenges, offering solutions that ensure both safety and longevity in these environments.

• Pools, Spas, Decks, and Marina Docks

  GRP grating products that provide a slip-resistant surface and exhibit remarkable resistance to water and chemicals are ideal for use around pools and marinas. For this rooftop pool deck at a Scottsdale, Arizona, apartment complex, glass reinforced plastic grating provided the optimal corrosion resistant solution for supporting turf while ensuring proper drainage and safety for residents. 

• Playgrounds and Water Parks

  For children's safety, GRP grating can be a top choice in playgrounds and water parks. The durability of GRP ensures minimal maintenance requirements while choosing a product with a slip-resistant surface minimises the risk of accidents.

• Fish Hatcheries

  Fish hatcheries like the ones in Hoodsport, Washington, rely on glass reinforced plastic grating due to its non-leaching properties which prevent the release of harmful materials into the water. It can also withstand the corrosive effects of salt water, making it indispensable in these environments. 

More than simply a workhorse material for walkways and drainage areas, glass reinforced plastic grating can also contribute to the visual impact and energy efficiency of buildings. It offers a wide range of aesthetic options along with the benefits of being lightweight and easy to install. It serves as an excellent choice for facade and cladding solutions as well as in sunshade and screen applications, providing privacy and effective shelter from damaging UV rays. The material’s weather resistance ensures longevity even in challenging outdoor environments.
