  • Mirror Polished Finish: Hand-buffed surface provides high reflectivity and prevents pitting.

Frequently Asked Questions

Will these hinges rust in high-salinity coastal environments?
No. These hinges are cast from AISI 316 Stainless Steel, which includes molybdenum. This specific alloy is engineered to prevent pitting and crevice corrosion even when submerged or exposed to constant salt spray, unlike lower 304-grade alternatives.
Are these strong enough for heavy engine room covers?
Yes. Each hinge plate is 5mm thick—significantly more robust than standard 2mm or 3mm stamped hardware. This solid construction provides unwavering support for heavy marine hatches and cabinetry without flexing under stress.
How do the 'left' and 'right' configurations work?
The hinges are designed as a matching set (Left and Right) for lift-off functionality. By installing them as a pair, you can slide the door or hatch off its pins instantly for maintenance access without needing to unscrew the mounting plates.

Our Roots

Hong Kong Based, 8 Years of Expertise

The story of AirowMarine began eight years ago. Headquartered in Hong Kong, we have been dedicated to the global operation and brand building of marine accessories.

Supply Chain

Invested Factories in Mainland China

To ensure our products withstand extreme environments, we are more than just a bridge for trade. AirowMarine has invested in its own manufacturing facilities in Mainland China. Leveraging the region's mature and efficient industrial supply chain, we are deeply involved in the entire process—from raw material selection and precision machining to final assembly. We avoid exaggerated claims; instead, through professional logistics and rigorous quality control, we ensure every product delivered to you meets high nautical-grade standards.
