Brief IntroductionIt is a plain carbon steel sheet coated in a galvanizing process that applies a barrier of zinc toinsulate it from the elements. Most of the corrugated roofing and siding products seen todayand for many years pastare made with a galvanized finish2. Roofing Sheet FinishAs with almost any product the finish of the galvanized metal finish will change over time. Aftera period of time, the surface will appear to have a white oxide look. When this happens thematerial is actually protecting itself from further damage. We stock and sell several corrugatedand decking panels in either a (G-60) or(G-90) level of galvanizing3. Application scopeIt is most commonly used for commercial, agricultural, and industrial purposes, however, it isnow also being recognized as an excellent form of residential roofing4. AdvantagesA normal steel sheet will rust almost immediately, but galvanizing will protect the steel. Thisgalvanized, eltro-coated, hot-dipped process produces a silvery look or spangled finish. Asa standard, several of our industrial metal siding, metal roofing, metal decking, corrugatedmetal panels and accessories are made in galvanized steel5.
