Aluminized steel is a kind of carbon steel treated by a hot-dip coating process on both sides with aluminum or aluminum-silicon alloy. This process aims to enhance its properties, particularly corrosion and rust resistance. Aluminized steel possesses the strength, hardness, and excellent mechanical properties of traditional steel while incorporating the attractive appearance of aluminum and its antioxidant properties. The perfect combination of these qualities makes aluminized steel a metal material with enhanced capabilities and wider applications.
Aluminized steel comes in two types, Type 1 and Type 2.
Aluminized steel Type 2 is hot-dip coated with pure aluminium. It is specifically designed for applications where atmospheric corrosion resistance is required.
Aluminized steel Type 2 and prepainted aluminized steel are recommended by CINI for insulated pipe jacketing in scenarios where there's a combined risk of corrosion and fire. These materials offer a balance of corrosion resistance and fire protection, making them suitable choices for such applications as per CINI guidelines.
