Military & Defence
CARC, IRR and specialist protective finishes for defence hardware, supported by comprehensive in-house pre-treatment capabilities.
Our processes are controlled and applied to exacting MIL specifications, delivering durable protection against corrosion, wear and demanding operating environments.
From individual components to production batches, every order is supported by rigorous process control, traceability and documentation — providing the approvals and assurance required across defence supply chains.
Finishing for the defence supply chain
Defence components demand protection that performs in the field — and the process control, traceability and documentation to stand up to the scrutiny of an audited supply chain.
We apply CARC, IRR and MIL-spec conversion coatings, supported by in-house pre-treatment and rigorous process control. Our finishing processes operate under Nadcap-approved control, with every order documented and traceable to provide the assurance defence programmes require.
As a JOSCAR-registered supplier, we understand the demands of working within the defence supply chain. From specification and processing through to inspection and release, we deliver finishes engineered for demanding environments and supported by the evidence required at every stage.
