GRP cabinets, enclosures and housings – a Sui Generis guide

GRP enclosures are a cost-effective way to protect your infrastructure.

They are commonly used as a robust and weather resistant covering for generators, compressors, pump houses and electrical boxes or to safely store equipment.

GRP is the ideal material for this purpose because it's cost-effective, long-lasting and needs virtually no maintenance.

Because of the flexibility of fibreglass, Sui Generis can create bespoke housing and cabinet units to your exact specifications and customise them to suit different environments.

And with the ability to go from design to installation in just a few weeks, you can count on your infrastructure being covered fast.

What kinds of enclosure can you build?

Fibreglass housing from Sui Generis can be customised to fit almost any shape – which means it can contain most kinds of structures that require extra protection from the elements. These are just some some examples:

  • Pump houses
  • Generators
  • Processors
  • Sprinkler systems
  • Plant houses
  • Electrical boxes.

We can also produce smaller cabinets for the storage of equipment and anything else you need to keep secure and protected from the elements.

Why GRP fibreglass to build an enclosure?

GRP is highly weather-resistant, which makes it much better than traditional materials at containing and protecting outdoor structures.

It's also impact-resistant, has a high strength-to-weight ratio and an indefinite life expectancy. Because it's light, it's also easy to transport.

And it's easy to manufacture in almost any shape you need, which gives us the flexibility to build GRP housing, enclosures or cabinets to suit your needs.

For harsh industrial environments, fibreglass cabinets can also be customised to withstand heat and chemicals, have anti-condensation roofs and be secure.

Best of all, you get lasting peace of mind much more cost-effectively.

Are there other benefits to fibreglass housing?

Many. These are just some of the properties of GRP cabinets and enclosures.

  • Corrosion Proof
  • Heat resistant
  • Leak free
  • Vandal resistant
  • Noise reducing.
