This International Standard specifies the characteristics of cold-reduced carbon steel sheet of commercial and drawing qualities coated by a continuous hot-dip aluminium-silicon alloy coating process. Aluminium-silicon-coated steel sheets are used for heat-resisting applications and also where both corrosion and heat resistance are required. The steel sheet is produced in a number of qualities, coating mass, grades, surface treatments and conditions designed to be compatible with differing application requirements. Aluminium-silicon-coated steel sheet can be ordered in one of two ordering conditions: a) Condition A): steel ordered to satisfy mechanical property requirements; b) Condition B): steel ordered to make an identified part.
