Steel sheet, hot-rolled, of structural quality with improved atmospheric corrosion resistance
This document specifies requirements for steel sheet hot-rolled of structural quality with improved atmospheric corrosion resistance, also known as weather-resistant structural steel. It is produced in the grades and classes listed in Table 1. The product is intended for applications where requirements are for mechanical properties and increased resistance to atmospheric corrosion. It is generally used in the delivered condition and is intended for bolted, riveted or welded structures. This document does not apply to the following steel qualities: — steels intended for boilers and pressure vessels, and steels designated as commercial quality and drawing qualities (see ISO 3573); — steels produced on reversing mills and designated with improved atmospheric corrosion resistance (see ISO 630-5); — steels designated with structural quality (see ISO 4995), and high yield strength structural quality (see ISO 4996); — steels designated with higher yield strength with improved formability (see ISO 5951).

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/patents).

4.1 This product is commonly produced in the range of thicknesses 1,6 mm up to and including
12,5 mm and widths of 600 mm and over, in coils and cut lengths.
4.2 Hot-rolled sheet less than 600 mm wide can be slit from wide sheet and will be considered as
not strip.
NOTE Hot-rolled sheet up to but not including 3 mm in thickness is commonly known as sheet. Hot-rolled
sheet 3 mm and over in thickness is commonly known as either “sheet” or “plate”.
