Protecting Edges, Crevices, and Irregular Steel Surfaces by Stripe Coating


This guide discusses the technique called stripe coating or striping as a way of providing extra corrosion protection measures on edges, outside corners, crevices, bolt heads, welds, and other irregular steel surfaces, including optional surface preparation techniques for sharp edges to improve coating performance. Some details, including the advantages and limitations of specific methods of obtaining additional coating thickness, are described to assist the specification writer in assuring that the project specification will address adequate corrosion protection.
