Cascadia Metals supplies Aluminized Steel products for a host of end-use applications. 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 material with a unique combination of properties as compared to steel or aluminum alone.
Aluminized Steel can be made using a variety of processes, but the most effective process is hot dipping. The process of hot dipping starts by cleaning the steel, placing it in a bath of aluminum and silicone (Type 1) or aluminum only (Type 2), and then removing it, allowing the coated steel to air dry.
Type 1 and Type 2 Aluminized Steels can be used interchangeably in most applications. Cascadia Metals supplies Type 1 Aluminized Steel which contains approximately 90% aluminum and 10% silicon.
- Improved Yield Strength & Structural Durability maintains strength yet easily formed
- Corrosion Resistance highly resistant, especially during exposure to salts
- Lower Cost as compared to other high-alloy steels
- Heat Resistance ideal for use where heat is involved
- Heat Transfer & Reflectivity reflects up to 80% of heat projected onto it while maintaining its strength
Our Type 1 Aluminized Steel
meets ASTM A463 requirements.
So you can rest assured our product will meet all standard specifications per ASTM.
A chemical surface treatment is available which consists of a thin, invisible, corrosion inhibiting, inorganic, chemical film applied on both sides of the metallic coated surface. This film is applied at the metallic coating line by dipping the steel strip into a solution of corrosion inhibiting chemicals. The chemically treated surface is much more resistant to staining that typically occurs in humid conditions during storage or transportation.
