Aluminized steel is carbon steel that has been coated with an aluminum-silicon alloy. This special coating provides excellent heat resistance, oxidation protection, and enhanced reflectivity. It is particularly suitable for applications exposed to high temperatures or corrosive environments.
One of the key uses of aluminized steel is in automotive exhaust systems, ovens, heaters, and chimneys. The aluminum layer acts as a barrier to prevent scaling and rusting, while the steel core retains the required structural strength.
Aluminized steel is available in Type 1 (aluminum-silicon coated) and Type 2 (pure aluminum coated). Type 1 is most commonly used for high-heat environments, while Type 2 is favored for more general corrosion protection needs.
In industries where both durability and thermal performance matter, aluminized steel offers an excellent balance between performance and cost.
