Container terminals, oil jetties and logistics zones along the Indonesian coast — Tanjung Priok, Patimban, Pelindo facilities — are a salt-spray environment that quietly eats ordinary fire cabinets. If a powder-coated box is rusting at the hinges two years after handover, the wrong material was specified. Here is how to get it right the first time.
The Salt-Spray Problem
Airborne chloride accelerates corrosion at every scratch, edge and fastener. Powder-coated carbon steel relies on an intact coating; once it is chipped during install or transport, rust spreads underneath. In a port, that timeline is measured in months, not years.
SUS 304 vs SUS 316
| Grade | Where it fits |
|---|---|
| SUS 304 | General port buildings, back-of-terminal, sheltered areas |
| SUS 316 | Direct salt-spray zones — quaysides, oil jetties, exposed container yards. The added molybdenum gives markedly better chloride resistance. |
For exposed marine positions, SUS 316 is the defensible choice; 304 is acceptable where the cabinet is under cover and set back from the waterline.
Standards Context
Hydrant and standpipe provisioning references SNI 03-1745, with port-authority and Kementerian Perhubungan (Kemenhub) safety requirements and local Damkar acceptance applying to the facility.
Note: standards and acceptance requirements are referenced by name for guidance only and are periodically revised. Always confirm the current edition and exact specification with your local fire authority or licensed consultant before procurement.
Specification Checklist
- Confirmed grade — 304 or 316 stated on the certificate, not "stainless" in general.
- Marine-grade fasteners and hinges — stainless throughout, not zinc-plated.
- Drainage — so washdown and condensation do not pool inside.
- Label localization — Bahasa Indonesia, plus your distributor or end-user branding.
SOKEI Fire builds SUS 304 and 316 stainless fire cabinets for marine and port use, with stainless hardware throughout and free Bahasa labelling. Tell us the exposure level and we will recommend 304 or 316 for the position.
