Copyright 2003 Hubbell, Screw Foundation System Design Manual for New Construction Chance Company7-1 Step 7 Corrosion GuideIntroductionCorrosion is defined as the degradation of a material or its properties due to a reactionwith the environment. Corrosion exists in virtually all materials, but is most oftenassociated with metals. Metallic Corrosion is a naturally occurring process whereby thesurface of a metallic structure is oxidized or reduced to a Corrosion product such as rust by chemical or electrochemical reaction with the environment. The surface of metallicstructures is attacked through the migration of ions away from the surface, resulting inmaterial loss over time.
understanding whether corrosion is a critical factor in a helical screw foundation application. This section is by no means intended as a rigorous design guide, but rather as a “first check” to see if corrosion is a practical concern given the specific project site conditions. A qualified corrosion engineer should be consulted for a site ...
