Located on the Atlantic Ocean, Long Island has historically been a center for fishing and seafood. As the biggest and longest island in the United States, Long Island is rich with beautiful ocean views. Sadly, the intoxicating seaside air is also rich with salt that can have a crippling corrosive effect on buildings and metal components.

Due to this challenging natural environment, a Long Island-based customer recently inquired with Waterson about a more durable closer hinge solution. She was struggling with lesser quality hinges that performed poorly in the salty environment. We explained to her that choosing the right hardware is critical for longevity, durability, and aesthetics. Heavy-duty 316 stainless steel door hinges make a world of difference in salty places like hers. Locating a marine-grade stainless steel product is surprisingly rather difficult, though. Luckily, Waterson has you covered!

Crafted with 316 marine-grade stainless steel, Waterson hinges stand up to the rigors of a harsh salty seaside environment.  316 stainless steel hinges tend to cost more, yet they are much more durable and reliable in rugged environments. Heavy-duty 316 stainless steels like the ones we use on our hinges at Waterson are much more weather resistant and less affected by chemical exposure due to chromium, nickel, and molybdenum elemental properties. Therefore stainless steel provides an impressive lifespan.  Some of the key benefits of 316 stainless steel include:

316 STAINLESS STEEL BENEFITS

  • Superior corrosion resistance

  • Chlorine resistance 

  • Offshore, marine & washdown applications
