1. Introduction

This Course explains the importance of using corrosion-resistant metal connectors and fasteners in the construction of coastal structures, areas using preservative-treated lumber, and any locations subject to contact with floodwater or windblown rain.

Post-disaster assessments of wood-framed buildings following natural hazard events such as high winds, floods, and earthquakes have revealed that structural failures frequently occur at connections rather than in framing members. In coastal areas, where higher moisture and humidity levels exist and buildings are exposed to salt spray, corroded metal connectors and fasteners have been observed to contribute to the loss of an adequate load path. The loss of an adequate load path often results in damage to or failure of the structure. This Course presents guidance on addressing and avoiding the corrosion of connectors and fasteners.

Questions pertaining to minimizing or avoiding corrosion of connectors and fasteners should be directed to the appropriate product manufacturers, local official, NFIP State Coordinating Office, or the Federal Emergency management Agency (FEMA) Regional Office.
