Leading GRP & Fibreglass Composite Manufacturing

Based in the heart of the UK, we provide a complete development and manufacturing service for a broad range of fibreglass and GRP parts. 

Different composite manufacturing processes are chosen to best suit the volumes and costs of a given project. Whether it is 100 or several thousand parts per year, we invest a high level of effort into the complete customer experience. 

Using the latest design software, 3D imaging and a variety of lamination techniques, Quantum can produce precise fibreglass and GRP parts for high specification applications.

40+ Years of UK Composite Manufacturing

Trust in a UK contract manufacturer with over four decades of specialist GRP and fibreglass expertise.

Founded in 1985, our commitment to quality has been a constant. Operating from our expansive 70,000 sq ft UK facility, you gain a production partner with proven longevity and the capacity to scale to your precise manufacturing requirements.

Our equipment and methods can currently handle part sizes up to 6m x 2.4m, or as small as 300mm3. We are continually investing in research and development, and have room to expand to meet our customers’ needs.

Glass Reinforced Plastic: a High Strength Composite

Leverage the superior performance of Glass Reinforced Plastic (GRP) and gain a competitive edge. Quantum is at the forefront of GRP manufacturing, investing in new processes and facilities to deliver:

  • High strength-to-weight ratio
  • Excellent corrosion resistance
  • Exceptional durability 
  • Repairable
  • Market-leading gel coat finish

Efficient, Quality Manufacturing

We know that project success relies on a manufacturing partner that is both precise and fast. Our GRP and fibreglass fabrication methods include hand lay, spray lay and RTM Lite.

  • ISO 9001 Quality Assurance
  • Expert manufacturing processes
  • Quotes within 2–7 days of enquiry
  • Typical prototypes in 3 months
  • External testing partners

With a choice of materials from established and reputable suppliers, including flame retardants, UV resistant, high strength, high gloss finish and high productivity options.

Our lead times depend on the project; the higher quality and complexity of some bespoke parts can lead to longer development phases. We will always discuss projected lead times with customers, to ensure expectations are aligned from the start.
