Tech Note D001- 23: Durability of Cold-Formed Steel Framing Members
Tech Note D001- 23: Durability of Cold-Formed Steel Framing Members

This Tech Note Updates and Replaces Tech Note D001-13

Summary: The purpose of this document 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.

Disclaimer: Designs cited herein are not intended to preclude the use of other materials, assemblies, structures or designs when these other designs demonstrate equivalent performance for the intended use. CFSEI documents are not intended to exclude the use and implementation of any other design or construction technique.

Tech Note D100-23: Corrosion Protection of Fasteners
Tech Note D100-23: Corrosion Protection of Fasteners

This Tech Note Updates and Replaces Tech Note D100-13

Summary: Moisture, airborne chemicals and pollutants can all combine to reduce the life of ferrous fasteners through corrosion. This Technical Note examines the corrosion process, available fastener finishes, methods of measuring corrosion and the relative durability of fastener finishes.

Disclaimer: Designs cited herein are not intended to preclude the use of other materials, assemblies, structures or designs when these other designs demonstrate equivalent performance for the intended use. CFSEI documents are not intended to exclude the use and implementation of any other design or construction technique.

Tech Note D200-23: Corrosion Protection for Cold-Formed Steel Framing in Coastal Areas
Tech Note D200-23: Corrosion Protection for Cold-Formed Steel Framing in Coastal Areas

This Tech Note Updates and Replaces Tech Note D200-12

Summary: Cold-formed steel framing may be subject to corrosion when exposed to moisture and salt, both of which are prevalent in coastal areas. The 2003 edition of this technical note, based on guidelines published by the Federal Emergency Management Agency (FEMA 1986) for metal connectors used in wood-framed construction, described the cause of accelerated corrosion in buildings located near the ocean and some larger saltwater bays, as well as the variation in the corrosive environments within a typical building. The 2007 update incorporated the results of a corrosion study by Dr. Ian Robertson of the University of Hawaii Department of Civil Engineering, funded by the U.S. Department of Housing and Urban Development (SFA 2006). The influence of terrain and wind direction on corrosion rates was added to the original document. This 2023 update includes revised referenced documents and improved guidance on the proper storage of materials. This technical note outlines available corrosion-resistant materials for cold-formed steel framing members and makes recommendations for buildings at various distances from the ocean and for different exposure conditions within an individual building.
