About the material

Galvalume carries an aluminum-zinc alloy coating, nominally 55% aluminum. The aluminum forms a stable oxide barrier that resists corrosion far longer in open, dry exposure, but it offers less sacrificial protection at cut edges than zinc alone.

Coating weights are given in the AZ designations — AZ150 and AZ50 in common use.

The practical rule most fabricators use: Galvalume for long-run roofing and siding where the panel is exposed and mostly uncut, galvanized where the sheet is worked, welded or in contact with concrete, mortar or treated lumber.

Grades, finishes, and availability may vary by branch. Please contact your local branch for current product availability.
