GRP fibreglass mouldings guide

GRP fibreglass can be moulded into almost any shape – which makes it an ideal, cost-effective product for automotive components and parts.

These can take the form of a standard range of products available at short notice or bespoke designs fabricated for specific vehicles or uses.

Sui Generis can produce these in a base colour for your own spray booth or in a high quality gel finish to your specifications – allowing the part to be fitted immediately onto the vehicle.

Because parts can be created to your designs, there are no limitation of which vehicles parts can be created for – from components for military vehicles to spoilers for sports cars.

What kind of parts can be made with GRP?

With GRP fibreglass, Sui Generis can fabricate an almost limitless variety of vehicle parts – you simply need to provide us with the designs. These are just some of the parts we've manufactured for our clients:

  • Cab roofs for Luton Transports
  • Fibreglass body shells
  • GRP cabinets
  • Chemical tanks for crop sprayers
  • Front and rear spoilers
  • Decorative panels.

Why use GRP fibreglass mouldings?

GRP is the building material of the 21st century, giving you the protection you expect from metal parts, while being lighter and more cost effective.

Fibreglass car parts have a very high strength-to-weight ratio because the material is impact-resistant and corrosion-resistant. As an added bonus, because units like our cab roof have one continuous surface, you won't face the hassle of tears or leaks.

For industries with vehicles that handle chemicals or can be exposed to high levels of heat, GRP is the first choice for automotive components. That's because it can be customised with resins and additives specifically to resist these elements.

This doesn't just contribute to your vehicle's durability, but to its safety too – giving you lasting peace of mind.

Are there other benefits to fibreglass moulds?

There are many. These are just some of the properties of GRP commercial vehicle mouldings:

  • Corrosion Proof
  • Indefinite lifespan
  • Leak free
  • Impact resistant
  • Customisable.

Do your GRP mouldings conform to regulations?

Yes. Sui Generis has robust quality assurance procedures in place to ensure our UK-based facility manufactures automotive moulding to the highest standards from quality fibreglass materials.
