Meeting the challenges of defence programmes
Defence manufacturing demands precision, reliability and compliance with rigorous international standards. Expromet delivers:

- Triple ISO and AS9100 certifications for quality assurance.
- ISO 3834 quality welding certification

All Expromet companies are fully accredited members of JOSCAR (the Joint Supply Chain Accreditation Register) – the industry-wide system used by defence and aerospace primes to pre-qualify suppliers.
For customers, this accreditation means reassurance that Expromet meets the strict standards required to supply into the sector. It reduces the burden of compliance checks and provides confidence in our ability to deliver with consistency, quality and integrity.
