No. The sheet metal parts pick-up-parts manufactures are made of electro-galvanized steel. This means the metal is electroplated with a thin layer of zinc by the steel manufacturer. There are several reasons for selecting this steel for our product: Electro-galvanized steel is clean and dry. The parts you receive are free of contaminants such as dirt and oil which would cause problems when preparing for paint. The zinc protects our parts from rusting during our processing and while on the shelf. You are assured of receiving a clean, rust-free part which may be painted with minimal preparation. After the parts are painted the zinc under the paint helps prevent loss of paint adhesion or rusting if the paint surface is scratched or damaged.
