How to Choose Material of Stainless Steel Railing Fittings? Aisi304, 316 or duplex 2205?

Posted on March 14th, 2022

Although not visible to the naked eye from stainless steel railing fittings, the variance between different grades of stainless steel lies in its composition. As steel is naturally corrosive, different elements are added to make it stainless.

The industry standard for interior handrail use is a 304 grade stainless steel. In comparison 316 stainless steel contains 2% molybdenum to make the material more resistant to corrosion caused cracks, tension and pitting.

For outdoor use we normally recommend 316 grade stainless steel as the tougher composition gives better resistance in these harsh environments.

For swimming pools, coastal areas, Highco Metal can provide a wide range of stainless steel railing fittings in 2205 grade.
