Capability enquiries by controlled channel

Fibreglass, engineered to defence-grade standards.

For three decades we've engineered fibreglass and composite components for demanding defence and security applications — discreetly, in-house, to specification. Public detail is deliberately limited; capability discussions happen directly with our technical team.

GemRock now leads with fibreglass repair. Defence work continues, by direct enquiry.

Capability areas

What fibreglass does for defence.

Indicative capability areas only. Specifications, standards and certifications are discussed under enquiry — figures below are placeholders.

Protective housings

Lightweight composite enclosures and panels engineered for impact and environmental protection.

Spec on enquiry

Low-signature structures

Non-conductive, low-radar-signature fibreglass for radomes and sensor housings.

Configuration to spec

Corrosion & weather

Holds up to salt, damp and extreme temperature where metal corrodes — marine and field-ready.

Environmental data on enquiry

Bespoke moulding

One-off and low-volume composite parts moulded to drawing, fully in-house.

Made to order

Weight reduction

High strength-to-weight composites that cut mass without giving up durability.

Placeholder

Quality & traceability

Documented, repeatable manufacture with material traceability through the build.

Standards on enquiry
Engineering approach

In-house, to specification, under control.

  • One foundry. Material formulation, layup and finishing all under one roof — nothing critical is outsourced.
  • Built to drawing. Multi-layer laminate configurations engineered to the requirement, not pulled off a shelf.
  • Discreet by default. Programme detail stays off the public site; we work to your information-handling rules.

How it works

A controlled enquiry, not a contact form.

Defence enquiries are handled person-to-person. Start with non-sensitive information only; we'll establish the right channel before any detail is exchanged.

Do not send classified, controlled or programme-sensitive information through the website. Share only what's needed to make contact.
