AZ150 indicates that in the triple spot test per EN 10346 standard, the minimum total coating mass on both surfaces is 150g per square meter. Equivalent to Total Both Sides in ASTM A792 standard is 0.50 oz/square foot.
Single surface coating thickness: 18 microns | Double surface coating thickness: 36 microns
The coating alloy composition (55% aluminum, 43.4% zinc, 1.6% silica) creates a passivating barrier against general corrosion while providing galvanic protection for exposed steel areas, scratches, and trimmed edges.
