## Sourcing pain points we solve

Seawater is a relentless corrosion test: pick the wrong alloy pair and galvanic attack eats a fitting in one season, so material selection — 5083, 316L, phosphor bronze — is the first engineering decision, not an afterthought. Watertight housings live on O-ring groove tolerances and surface finish, where one bad groove floods the electronics it protects. Classification societies (DNV, ABS, CCS) require certified materials and documented processes on critical components. Vessel and offshore schedules are brutal: a part missing at dock means a ship that does not sail.

## Typical parts

- Watertight enclosures and connector housings
- Sonar and transducer mounts
- Deck hardware and rigging fittings
- ROV/AUV frames and thruster components
- Bronze bushings and shaft-line components

## Certifications & standards

- **DNV / ABS / CCS**: We understand classification-society requirements for critical marine components, including certified materials and documented process records.
- **ISO 9001**: We understand marine buyers expect ISO 9001 process discipline with corrosion-conscious material control on every order.
- **EN 10204 3.1**: We support EN 10204 3.1 material certificates plus salt-spray test documentation where the application demands it.

_We understand and support these requirements; certification and documentation scope is confirmed per order — we do not claim to hold certifications on this page._
