Specifications include, but are not limited to: Kansas Correctional Industries is seeking to engage into Contract for Metal Galvanizing Services. Surface preparation for galvanizing typically consists of three steps: caustic cleaning, acid pickling and fluxing. The bath chemistry is specified by the American Society for Testing and Materials (ASTM) in Specification B6. The bath temperature is maintained at about 840°F (449°C). The articles are cooled in either water or ambient air immediately after withdrawal from the bath. Because the galvanizing process involves total material immersion, it is a complete process; all surfaces are coated. Galvanizing provides both outside and inside protection for hollow structures.
