Figure 2 shows the peeling of galvanized .... Regular galvanized is approximately 99.7% zinc coated. Galvannealed offers a surface with more of a matte finish and more porosity. Its paint adhesion properties are excellent. The coating is composed of approximately 90% zinc and 10% iron. Galvalume coatings are 55% aluminum, 43.5% zinc, and 1.5% silicon. This is because when heated to high temperatures, the coating gives off toxic fumes. I don't know what level of heat is required for that to happen but a wood stove can get pretty hot, and I don't remember seeing one made out of galvanized metal. Ergo, I'd err on the side of caution and stick with traditional materials. Galvanized Steel. The process of welding galvanized steel is commonly found in the metal fabricating industry.
