Aluminized steel is steel that is coated with aluminum during the milling process.
Aluminized Steel Characteristics
Aluminized steel was developed for providing more structural durability and a high yield strength in highly corrosive environments. Aluminized steel is carbon steel coated, through the hot-dip process, with an aluminum-silicon alloy. This process assures a tight metallurgical bond between the steel sheet and its aluminum coating, producing a material with a unique combination of properties possessed neither by steel nor by aluminum alone.
The aluminum coating provides resistance to high temperatures and has a bright appearance. Aluminized steel is perfect for high-heat situations.
It retains its original appearance up to 900 degrees F, reflecting up to 80 percent of the radiant heat in its environment. This higher-heat resistance, combined with the superior corrosion resistance of the aluminum and silicon alloy coating, provides a better heat and corrosion solution than a lower melting temperature material such as zinc-coated (galvanized) steel.
