| SUMMARY |
This Technical Note was originally published
as TN140. 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 causes 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.
This 2007 update incorporates the ongoing 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. The influence of terrain
and wind direction on corrosion rates has been added to the original document.
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.
