galvanized steel coil

Galvanized steel is used for standard roof flashings, gutters, downspouts – most every sheetmetal product. Galvanized typically requires preparation in order to be painted – Bonderized (AKA Paintlok) is paint-ready galvanized. All of our galvanized is G90, ASTM A653.

Galvanization is a zinc coating applied to steel. Once the coating is gone, you just have bare steel. G90 galvanized is superior to G60, which is why we only carry G90. G90 Galvanized gutters will last up to 30 years if properly maintained (and depending on environmental conditions). If you let leaves sit in the bottom, they will rust through in a matter of a few years.
