Aluminized steel

The product has a unique combination of properties possessed by neither steel alone nor aluminium alone.

Common applications include heat exchangers in residential furnaces, commercial rooftop HVAC units, automotive mufflers, ovens, kitchen ranges, water heaters, fireplaces, barbecue burners, and baking pans.

These thin layers also keep pit corrosion from occurring, especially during exposure to salts that affect most other metals.

In North America nearly 700,000 tons of aluminized steel are consumed annually.
