Stainless steel is a very durable architectural material. When an appropriate stainless steel, surface finish, and design are selected and it is properly maintained, stainless steel’s appearance will remain virtually unchanged over the life of the building or structure. IMOA has developed selection guidelines based on the assumption that corrosion staining is aesthetically unacceptable even if there is no structural deterioration. The Stainless Steel Evaluation System is designed for use by architects, contractors, and others involved in stainless steel selection.
The system explains the factors that must be considered when selecting stainless steel for exterior applications using a simple scoring system. It consists of a software program and brochure outlining the system, case studies from around the world, and links to the data that you need to evaluate a site (pollution, corrosion maps, climate).
The score should be viewed as a guideline that generates an initial evaluation of stainless steel requirements. The effectiveness of the Stainless Steel Evaluation System is dependant on the user’s correct assessment of the design and site conditions. It is not a precise scientific determination. If your final score is above "3", or if you are not sure whether you have evaluated an application correctly, obtain assistance from a stainless steel corrosion expert with architecture experience (contact IMOA at firstname.lastname@example.org for details). If the design characteristics, maintenance schedules, or exposures of components vary significantly, calculate a score for each application.
