scope:

This International Standard applies to hot-rolled steel strip of structural quality in the grades and classes listed in Tables 1 and 2, usually without the use of microalloying elements. This product is intended for structural purposes where particular mechanical properties are required. It is generally used in the delivered condition and is intended for bolted, riveted or welded structures. It is rolled on a narrow strip mill.

This product is commonly produced in thicknesses from 0,65 mm to 12 mm inclusive and widths up to 600 mm exclusive, in coils and cut lengths.

This International Standard does not cover strip steels designated as commercial quality or drawing qualities (covered in ISO 6317, Hot-rolled carbon steel strip of commercial and drawing qualities) or steels intended for boilers or pressure vessels, or steels to be rerolled to cold-reduced products, or steels designated as weathering steels, having increased atmospheric corrosion resistance.
