When choosing between GRP grating and steel grating, it’s important to consider long-term performance, safety and cost. Steel has traditionally been the material of choice, but in recent years GRP has risen as a strong competitor, especially where safety and low maintenance are priorities.
Our GRP grate flooring complies with British and international standards, including BS4592 and EN14122, and offers excellent fire-retardant and chemical resistance properties. Elemy’s grating is suitable for sectors ranging from oil & gas, utilities, and rail to food processing and marine environments.
Compared to steel, GRP grating requires no hot works, is non-conductive, and doesn’t rust or degrade, making it ideal for long-term applications with minimal maintenance. Choose from a variety of thicknesses and mesh sizes to suit your project needs.
Weight and Ease of Installation
One of the most obvious differences is weight. GRP grating is up to 50% lighter than steel, which makes it easier to transport and install. This eliminates the need for heavy machinery, reducing both installation time and costs. Steel, on the other hand, requires welding, cutting and lifting equipment, which can extend project timescales and budgets.
Corrosion Resistance
Steel corrodes quickly without protective coatings. In contrast, GRP grating is resistant to rust, rot and chemical attack. This makes it particularly valuable in marine environments, chemical processing plants and utility sites. While steel must be painted or galvanised to prolong its life, GRP requires no such treatment.
Safety and Functionality
- GRP grating: Non-conductive, slip resistant, and safe to handle without hot works.
- Steel grating: Conductive, slippery when wet, and requires hot cutting/welding, which introduces site safety risks.
For industries such as oil & gas or rail, the non-conductive nature of GRP makes it far safer.
Maintenance and Costs
Although steel may appear cheaper initially, the ongoing costs of painting, galvanising and replacing corroded panels make it more expensive over its lifecycle. GRP grating requires minimal upkeep and typically lasts over 25 years, offering better value for money in the long run.
Environmental Impact
GRP has the added advantage of being sustainable in terms of lifespan and reduced waste. With fewer replacements needed, it contributes to more environmentally responsible projects.
