Examples of Prepainted Aluzinc 150 GSM Steel Coils in practical applications are as follows:
Prepainted Aluzinc 150 GSM Steel Coils Substrate Selection:
AZ150 (aluminum-zinc plating amount of 150g/m2;) G345A high-strength aluminum-zinc-plated steel plate (55% aluminum, 43% zinc and 1.6% silicon)
Prepainted Aluzinc 150 GSM Steel Coils Corrosion Resistance Data:
5%NaCL 35℃, 1000Hrs, Field is good, Scribe No Blister below 2mm.Q.U.V: 2000hrs, color difference MAX.2, light retention rate above 90%.
The above data shows that the galvanized color-coated sheet (AZ150, G345A, PVDF) is very suitable for buildings or other facilities in extreme environments, and it is extremely resistant to corrosion and weather. service life of more than one year. In addition, prepainted aluzinc 150 GSM steel coils have been widely used abroad and have good economics, which is also a domestic development trend.
The substrate is compared with galvanized 100g/m2 (Z100) and aluminum-zinc 70g/m2 (AZ70)
