GRP Gratings vs Steel Gratings

When choosing the right grating material for your applications, two options stand out: GRP gratings and traditional steel gratings. Each of these materials has its own set of strengths and weaknesses, making them suitable for different scenarios. 

In this blog, we’ll compare GRP gratings with steel gratings to help you make an informed choice for your specific needs.

Key benefits and features we’ll cover include:

  • Durability and corrosion resistance
  • Weight and installation
  • Electrical conductivity
  • Chemical resistance
  • Maintenance

Durability and Corrosion Resistance

GRP Gratings: Renowned for their exceptional durability and resistance to corrosion, GRP gratings are often the go-to choice when it comes to durability and corrosion resistance. They are impervious to moisture, making them ideal for outdoor and marine applications. Unlike steel, they won’t rust or corrode, even in harsh environmental conditions. 

Steel Gratings: Steel gratings, while strong and durable, are prone to corrosion, especially in humid or corrosive environments. To mitigate this, steel gratings require regular coatings or galvanisation, which adds to maintenance costs. Without proper maintenance, steel gratings can deteriorate over time, leading to safety concerns.

Weight and Installation

GRP Gratings: Compared to steel gratings, GRP gratings are significantly lighter. This lower weight simplifies installation and reduces labour costs. It also makes them a preferred choice for applications where weight restrictions are a concern, such as rooftop walkways or elevated platforms. Additionally, the lightweight nature of GRP gratings makes them easier to handle during maintenance or replacements.

Steel Gratings: Steel gratings are heavy, and their installation typically requires specialised equipment and skilled labour. The weight of steel gratings can complicate the transportation and installation process. This can lead to longer installation times and higher installation costs compared to GRP gratings.

Electrical Conductivity

GRP Gratings: GRP gratings are non-conductive and offer excellent electrical insulation. This feature makes them suitable for applications where electrical conductivity is a safety concern, such as in areas where electrical hazards exist.

Steel Gratings: Being highly conductive, steel gratings can be problematic in environments where electrical insulation is needed. Special precautions are required to mitigate the risk of electric shock in areas that use steel gratings.

Chemical Resistance

GRP Gratings: When it comes to chemical resistance, GRP gratings are the number one choice for you. They are resistant to a wide range of chemicals, making them suitable for use in chemical plants, wastewater treatment facilities, and other corrosive environments. When it comes to chemical resistance, GRP Gratings are undoubtedly the best choice.

Steel Gratings: Steel gratings are susceptible to corrosion from certain chemicals, and their longevity in such environments can be limited without additional protective coatings. If you select Steel Gratings, especially within corrosive environments, they are likely to have a reduced lifespan and therefore will be more costly to replace.


GRP Gratings: Unlike steel gratings, GRP gratings require minimal maintenance. Routine cleaning with water and mild detergents is typically all that’s needed to keep them in good condition. This low maintenance requirement results in cost savings over time.

Steel Gratings: Steel gratings require regular maintenance, including cleaning, repainting, and anti-corrosion treatments to prevent rust and maintain structural integrity. These maintenance tasks can be labour-intensive and costly.

The choice between GRP and steel gratings ultimately depends on your specific application and requirements. If you prioritise durability, corrosion resistance, low maintenance, and electrical insulation, GRP gratings are the superior choice. 

Ultimately, the decision should be based on your project’s unique needs and budget. Carefully consider the benefits and drawbacks of each material to make an informed choice that ensures safety, longevity, and cost-effectiveness in your application.
