Products Description
Weight of AI-Zn Coating
We mainly sell AZ50, AZ55, and AZ150 galvalume steel coils. AZ50 and AZ55 are ASTM A792 standard coating designations, meaning weights of 0.50 ounces/square foot and 0.55 ounces/square foot. AZ150 is a coating designation according to EN 10346 standard, which means the weight is 150g per square meter.
AZ50 is equivalent to AZ150;
AZ55 is equivalent to AZ165;
In addition we can also produce galvalume with lower coating weight, please contact sales.
