The problem:

Mill scale

Mill scale is a type of iron oxide that is formed on the surface of the steel during the hot-rolling process. The very high surface temperature combined with high roller pressures result in a smooth, bluish grey surface.

If mill scale were a uniformly well-adhered covering to the steel section, then it would make an ideal protective barrier. Unfortunately, mill scale is not uniform, nor is it well-adhered. This latter item is of concern in that many projects have had high quality, expensive protective coatings applied directly over mill scale and inadequately prepared steel only to have the entire structure and coating system fail within a very short period of time.

All mill scale must be removed to present a uniform and clean surface.
