Marine Grade Stainless Steel Sink (316L)
Zibo Cook manufactures marine-grade stainless steel sinks for boats, yachts, offshore platforms, and marine food service operations. Our marine sinks use 316L stainless steel, which contains molybdenum for superior resistance to saltwater corrosion – essential for marine environments where standard 304 steel would quickly corrode. Whether you are outfitting a single yacht galley or a fleet of fishing vessels, every unit ships with a 316L material certificate, and we build to MOQ 1 unit with 3-5 day production.
Why 316L for Marine Applications
- Saltwater resistance: Molybdenum content prevents pitting and crevice corrosion
- Low-carbon (L) grade: Better weld integrity – weld zones resist sensitization and rust
- Longevity: Withstands years of exposure to salt spray and humidity
- Food safety: Non-porous surface meets marine food service hygiene standards
- Low maintenance: Requires minimal upkeep in harsh marine conditions
304 vs 316L at a Glance
Not sure the upgrade is worth it? The differences that matter on the water:
| Property | 304 | 316L |
|---|---|---|
| Chloride/salt resistance | Moderate – pits in salt spray | Excellent – molybdenum added |
| Weld zone corrosion | Can sensitize and rust | Low carbon keeps welds stable |
| Typical marine lifespan | Short – pitting within seasons | Years of salt spray exposure |
| Best use | Inland and enclosed galleys | Open decks, offshore, fishing fleets |

Frequently Asked Questions
Why can’t I use regular 304 stainless steel on a boat?
304 stainless steel will corrode and pit when exposed to saltwater. 316L contains molybdenum, which provides the corrosion resistance needed for marine environments.
Can you make sinks for specific boat layouts?
Yes, we customize dimensions and mounting configurations – including gimbal mounting – to fit your vessel’s galley layout.
What is the minimum order quantity?
1 unit. Single-vessel refits and one-off galley upgrades are welcome; fleets can order in volume at the same fast lead time.
How fast can you deliver?
Production takes 3-5 days for standard and most custom configurations. Samples ship in 3 days; large batch orders with special finishes add roughly 5 days.
Is the 316L grade verified?
Yes – every order ships with a mill test certificate confirming the 316L composition, so you can verify the grade on arrival.
Do you also make matching 316L work surfaces?
Yes. Our 316 fabrication service builds prep tops, drain tables, and splash guards in the same grade and finish, so your galley is consistent throughout.
Do you ship to the USA and Europe, and who handles customs?
Yes – we ship worldwide with DDP door-to-door service to the US and EU. Duties, import paperwork, and customs clearance are handled by us before delivery.
What payment terms do you offer?
