The Methods We Use

Our team masters the four most common fibreglass application methods:

Hand lay-up, spray lay-up, vacuum bagging and vacuum infusion.

Each fibreglass project is specific and requires a different manufacturing approach. At GRP Composites, we can help to choose the best production process based on your own requirements.

Fibreglass hand & spray lay-up method

Hand and spray lay-up methods are the most commonly used when it comes to low volume parts production and prototypes. The main advantages of these methods are: low-cost molding + application, and most importantly, there are no size limitations for the parts that can be produced.

The process is to add the fiber reinforcements into a mould and then the resin is applied with a brush, roller or a spray gun.

Fibreglass vacuum infusion & Bagging method

Vacuum infusion and bagging methods are “more advanced” fibreglass manufacturing processes. The main advantage of these methods is to obtain a better strength/weight ratio.

However, the cost of production is significantly increased compared to hand & spray lay-up methods and it might not be suitable for very large parts.

Perfect Finish Guaranty!

GRP Composites high quality production standards also apply to the final step: “polishing“.

All parts produced are hand polished by our qualified staff and rigorously controlled by the production manager before we deliver to our customers.
