Summary

Forest Product Laboratry researchers investigated the corrosion of fasteners in new wood preservatives for several years. Their findings appear in the report: Corrosion of Fasteners in Wood Treated with Newer Wood Preservatives, which serves as a desk reference for engineers to aid in materials selection when building with treated wood. The research addresses these pertinent questions on designing durable connections with new preservative treatments: (1) How rapidly do embedded metals corrode in wood (2) What is the mechanism of corrosion in treated wood (3) Do extractives affect corrosion (4) How can we rapidly determine the service life of metals in wood (5) How can we use corrosion data to predict service life of metals in wood (6) Do suitable non-metallic fasteners for use in wood exist and how durable are they The research was conducted as part of the Research, Technology, and Education portion of the National Historic Covered Bridge Preservation Program administered by the Federal Highway Administration.
