What are the differences between Aluzinc galvalume steel coils and Galvanized steel coils?

Aluzinc galvalume steel coils and galvanized steel coils are both widely utilized in a variety of sectors, however they differ significantly. Here is a comparison between the two:

Coating Composition

Aluzinc galvalume steel coils have a covering made of aluminum, zinc, and silicon. This formulation increases corrosion resistance and improves performance in tough situations. In contrast, galvanized steel coils are coated with pure zinc. While galvanized steel provides corrosion protection, it may be less effective than Aluzinc galvalume steel in particularly corrosive or maritime situations.

Corrosion Resistance

Aluzinc galvalume steel coils have better corrosion resistance than galvanized steel coils. The combination of aluminum and zinc in the coating has a synergistic effect, with the aluminum acting as a barrier layer and the zinc providing sacrificial protection. This dual protection method provides increased resistance to rust and corrosion, making Aluzinc galvalume steel coils ideal for applications involving moisture, chemicals, and corrosive factors.

Heat resistance

Aluzinc galvalume steel coils are generally more heat resistant than galvanized steel coils. The presence of aluminum in the coating increases the steel’s capacity to resist high temperatures without significantly altering its structural qualities. Galvanized steel coils, while still heat resistant, may show discoloration or surface changes if exposed to high temperatures for an extended period of time.

Aesthetic appeal

Galvanized steel coils have a distinctive brilliant, silver-gray look due to their pure zinc coating. In contrast, Aluzinc galvalume steel coils have a smooth, glossy surface that can be coated with a variety of colors and finishes. This increases aesthetic versatility and customization choices to satisfy unique design requirements.
