Properties of GRP vs Steel

GRP Gratings are STRONGER & CHEAPER THAN STEEL Gratings

GRP gratings are an excellent alternative to steel gratings. The many properties of GRP mean that, when compared to steel gratings, GRP alternatives are the most sensible decision in a scenario where steel was previously thought to be the best choice.

Steel gratings are renowned for being extremely strong and are often used because of their durability and adaptability. However, despite the many qualities that steel has, GRP gratings often outperform when it comes to all round use.

GRP can be moulded to a variety of shapes and is used for a range of useful and adaptable products. In environments where steel would be used underfoot,  GRP Grating is a safer and more durable alternative. Similarly, GRP Gates and Fencing is a cost-effective solution to any area that requires a maintenance free, safe, high-strength solution that is more effective than steel alternatives.

Strength of GRP

When put to the test, the strength of GRP comes into its own. Usually GRP is used in situations where there is continuous pedestrian footfall, medium weight loading bays and, occasionally, heavy weight loading areas over narrow drains and gullies.

As an example: If you use a 25mm, 1 metre wide grating that is supported on 4 sides, it will easily withstand 1/3 ton per square metre. While a 38mm grating can reach 1⁄2 ton per square metre.

The performance improves when the width of the area is reduced. At 300mm wide, the 38mm grating can withstand loadings in excess of 12 tons.

Anti-Slip Surface

In situations where water or moisture present a hazard, GRP is a far better solution than steel. When wet, steel becomes slippery underfoot, which can easily lead to accidents and personal injury.  

With GRP, there are no such worries. GRP products have a great reputation for their ­slip resistance and have been awarded an “excellent” pass in tests carried out to BS 7976-2:2002.

Corrosion Resistant

As a result of the resins used in GRP gratings, they offer a high resistance to corrosive substances over a wide pH range. If you're unsure whether our GRP products will hold up better than your steel gratings, we can carry out tests to ensure they are resistant to all potential chemicals at use in or around your area.

UV Stability

GRP gratings are manufactured with a high-quality UV inhibitor to prevent any UV degradation. This makes them an ideal material for use outdoors, on roofs and other areas exposed to the elements.

Water and Fire Resistant Gratings

GRP is resistant to water and fire. Our products contain a fire-resistant additive and attain a EURO Class 1 and BS EN ISO 11925-2. This gives a 25-minute burn time on material, don't need to.

Colour Pigmentation

No treatments such as powder coating or spray painting are required for our GRP products. A process of constant mixing of pigmentation and resin ensures a moulded-in colour. Standard stock colours are green, grey and yellow, and bespoke colours are available on request.

Lightweight Gratings

Steel gratings are heavy and difficult to assemble. GRP gratings make a great alternative because they are a one third the weight of steel. This makes it easier to transport around and install into any desired area. Installation is not only easy, but it is also fast. Once the gratings are installed, they require hardly any maintenance.

Quality Assurance

The structural integrity of the GRP grating is high grade and is manufactured in accordance to ISO 9001. The lifespan of our GRP products is dependent on a number of factors including environment, maintenance and the nature of its use.

Maintenance

GRP gratings require next to no maintenance and are extremely durable, resisting weather conditions and chemicals. Plus, GRP also has no scrap metal value, making it ideal if you have had any previous bad experience with metal being stolen.

Colour Pigmentation

No treatments such as powder coating or spray painting are required for our GRP products. A process of constant mixing of pigmentation and resin ensures a moulded-in colour. Standard stock colours are green, grey and yellow, and bespoke colours are available on request.

Given the extensive list of GRP properties, it is apparent why this material is growing in use as an alternative to steel gratings. GRP not only excels but also demonstrates itself as a superior material altogether. It is affordable, easy to install and maintain, and lasts in all conditions.
