Galvalume vs Galvanized

Differences Between Galvalume and Galvanized metal finish

1. Galvanized panels are those in which the substrates are coated with zinc. Galvalume substrates are coated with an alloy of zinc and aluminum.
2. Galvalume performs better in harsher environments and offers better heat reflectivity properties.
3. Galvanized products may take longer to show rust but has inferior corrosion protection properties once rust begins. Galvalume on the other hand may rust earlier than galvanized products but has a much superior corrosion protection in the long term.
