A very popular choice with excellent corrosion resistance and good qualities of strength. Slightly cheaper than 316 Grade, it is a durable and aesthetically pleasing choice for all construction applications.
316 Grade
The addition of molybdenum to the mix is what sets this Marine Grade Stainless Steel apart. Used in highly corrosive environments, this grade is the ultimate choice for structures built close to or even within the ocean or bodies of water. There is no better material for fasteners designed for coastal applications, including docks, jetties, decks, fences and roofs.
