Frequently Asked Questions

Will this fitting rust in a saltwater environment?
No. Unlike standard 304 steel, this fitting is constructed from premium Grade 316 Stainless Steel, which contains molybdenum for superior resistance against pitting and corrosion in saline conditions.
Does it include the mounting screws for the deck?
This unit includes the internal set-screws to secure the 7/8" tubing, but deck mounting screws are sold separately to ensure you can choose the correct length and thread type for your specific hull material (fiberglass vs. wood).
Is the 90-degree angle precision-welded for heavy loads?
Yes, the tube-to-base joint is precision-welded and then mirror-polished to provide maximum structural integrity for handrails and awning supports, capable of withstanding high-torque marine movements.

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. These eight years of experience have taught us that on the unpredictable sea, every single component carries the trust and safety of the boat owner.

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.
