Protective Coatings for Highway Metals
This report relates steps taken to minimize coatings maintenance on metal appurtenances; particularly steel beam guardrail, bridge railings, and bridge structural steel girders. The Department has found that galvanizing guardrail and bridge railings yields a coating system that protects the materials at least twice as long as paints. In the course of these studies, a variety of alternative railing materials were tried including aluminum-alloy, unpainted low alloy steel, and concrete. For coating bridge structural steel girders, the Department has conducted laboratory screening tests on paint systems followed by in-service tests of the superior systems. Various coatings systems and Departmental specification revisions are discussed. Recently, the Department has required that low alloy, unpainted steel be used for bridge girders.
