Materials
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. Thus ZINCALUME® steel is able to last up to 4 times longer than galvanized steel (GI) and pre-painted galvanized steel (PPGI). ZINCALUME® steel supplied by BlueScope Steel (Malaysia) Sdn Bhd has a clear resin coating which gives it a beautiful, satin-smooth finish.
Clean COLORBOND® steel, AZ150 G550
Clean COLORBOND® is the pre-painted ZINCALUME® steel with the ability to prevent tropical dirt staining and better colour retention. Clean COLORBOND® paint system is oven cured with nominal gloss of 25% which conforms to Australian Standard AS2728 Category 3. It is certified to BOMBA Class ‘O’ (AS1530) with heat resistance up to 100° C.
