produced by NAHB Research Center, a subsidiary
of the National Association of Home Builders (NAHB) in the US and sponsored by International Zinc Association
Durability of Galvanized Steel Framing in Residential Buildings was a study commissioned by the International Zinc Association (IZA) that measured actual zinc and zinc-alloy coating corrosion rates of steel framing samples in four different home environments in the US and Canada over a ten year period. The NAHB Research Center was the research contractor.
