Differences Between Galvalume and Galvanized metal finish
- Galvanized panels are those in which the substrates are coated with zinc. Galvalume substrates are coated with an alloy of zinc and aluminum.
- Galvalume performs better in harsher environments and offers better heat reflectivity properties.
- 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.
