The Steel Supply Company began in 1898 as a manufacturer of paint and specialized in steel coatings. Over the years, the company has learned some things about coatings, steel, rust inhibition, and protecting steel from the elements. So, when a situation arose in the field regarding coatings, there were no better people to consult with. Sandy Liedeker, grandson of the founder Abraham Liedeker, began his career in 1952, eventually becoming a paint chemist. Whenever we reached out to him for help or information regarding a coating issue his most common response was, and still is, “surface preparation.”
