Main Advantage of Galvalume Steel
Especially produced for various usage purposes Long life of 4 times longer than other normal fffective corrosion sheets good heat resistance.
1. More fluent and smoother surface and superior corrosion resistance property than hot dipped zinc galvanized steel coils.
2. Excellent heat resistance durable ability and anti-oxidation performance. It can bear temperature under 315℃ without tarnish and can be applied normally under 500℃ for long period. They could reject erosion from water and mud. They are the ideal steel materials for water heating machines, food dehydrators, exhausted tubes, automobile mufflers. And its heat reflection ratio is more than 75% which is double of zinc coated galvanized steel. Heat resistance of the 55% aluminum-zinc alloy steel plate is better than that of the galvanized steel sheet, similar to the high-temperature oxidation resistance of the aluminum plate.
3. Excellent performance for coating and machinability. It is highly adhesive to organic color pre painted coatings, and it could be welded and processed as the zinc galvanized steel metals. And it could be cold bent and punching while getting beautiful outlooks. It is also cost savings as a smaller amount of base metal consuming for the same thickness, as aluminum is lighter than zinc density.
