ISO 3575:2025

This document specifies the requirements for steel sheet, in coils and cut lengths, metallic-coated by the continuous hot-dip process, with zinc and zinc-iron alloy coatings. The product is intended for applications requiring corrosion resistance, formability and paintability. The steel sheet is produced in a number of designations, coating masses, surface treatments and coating conditions designed to be compatible with differing application requirements. This document does not cover steel designated as structural quality, which are covered in ISO 4998.[1]
