What is Galvalume?

Galvalume is a flat-rolled steel sheet coated with an aluminum-zinc alloy (55% aluminum, 43.4% zinc, and 1.6% silicon) using a continuous hot-dip process. This innovative product is the result of over 20 years of research, combining the strength of steel with the corrosion resistance of aluminum and zinc.

• Enhanced Durability: The combination of aluminum and zinc offers unmatched durability and resilience in harsh weather conditions.

Corrosion Resistance of Galvalume Sheets

Salt Spray Test

The Salt Spray Test is a proven method to showcase the high corrosion resistance of Galvalume steel. The 55% Al-Zn alloy coating offers dual protection:

• Barrier Protection: The aluminum creates an insoluble oxide layer, serving as a barrier against corrosion.
• Sacrificial Protection: Zinc provides sacrificial protection at cut edges, scratches, and areas of coating damage, ensuring the sheet remains intact over time.

Exposure Test & Cut Edge Protection

Over 20 years of exposure testing in diverse atmospheric environments has demonstrated that Galvalume sheets offer superior cut-edge protection compared to galvanized steel sheets. This protection ensures long-term durability, even in areas prone to scratches and coating damage.
