A home is one of the few necessities that consumers expect to last a lifetime or more. For commercial property owners, each structure represents a significant investment. It is critical therefore, that the framing material performs its function for as long as other critical components, such as the roof structure, exterior and interior wall coverings, and flooring. For sufficient longevity, cold-formed steel framing needs proper corrosion protection. Galvanizing is one of the most economical and effective ways to protect steel. Steel framing materials used in residential and light commercial construction can be effectively protected by a galvanized coating.
This document from the Cold-Formed Steel Engineers Institute is to give engineers, architects, builders and home and commercial building owners a better understanding of how galvanizing (zinc and zinc alloy coatings) provides long-term corrosion protection to cold-formed steel framing members. This document also suggests guidelines for selecting, handling and using these steels in framing applications.
