Stainless steel is used in all aspects of architecture, building and construction. While it has been used in this industry since the 1920’s and is not a new material, stainless steel’s use and range of applications has been growing.
Some applications are highly visible and stainless steel is both aesthetic and functional, such as curtain wall and roofing. Others are practical, safety related and sometimes hidden, like masonry and stone anchors, bollards and safety railings.
Air pollution, salt exposure, weather patterns, design and cleaning frequency must be considered when selecting stainless steel and other construction materials if good long term performance is desired.
In applications with coastal or deicing salt, industrial pollution, volcanic or other corrosive environment exposure, a molybdenum containing stainless steel with a smooth surface finish is needed unless frequent cleaning is acceptable.
Molybdenum improves pitting and crevice corrosion resistance, which is particularly helpful in preventing staining due to salt and corrosive pollution damage.
