This document covers the following types of surfaces of steel structures consisting of carbon or low-alloy steel, and their preparation:

- uncoated surfaces,

- surfaces thermally sprayed with zinc, aluminium or their alloys,

- hot-dip-galvanized surfaces,

- zinc-electroplated surfaces,

- sherardized surfaces,

- surfaces painted with prefabrication primer,

- other painted surfaces.

This document defines a number of surface preparation grades but does not specify any requirements for the condition of the substrate prior to surface preparation.

Highly polished surfaces and work-hardened surfaces are not covered by this document.
