About Us

National Acid Proofing, Inc. was founded in 1952 by Ralph T. Histed to provide quality solutions to demanding corrosive conditions found in industrial environments. Since that time, we have specialized in corrosion-resistant masonry as it applies to various food and chemical manufacturing and processing industries.
