This document covers the following types of surfaces of steel structures consisting of carbon or lowalloy 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.
