ZINCALUME® steel, AZ150 G550

ZINCALUME® steel is a high-tensile G550 steel with a minimum yield strength of 550Mpa and a metallic coating with composition of 43.5% zinc, 55% aluminium & 1.5% silicon (AZ150) which conforms to Australian Standard AS1397 and Malaysian Standard MS1196. The practical and aesthetic merits of ZINCALUME® steel include durability, longer lasting life, formability and excellent corrosion resistance.
