1. Stronger Corrosion Resistance: The galvalume coating consists of 55% aluminum, 43.5% zinc, and 1.5% silicon, forming a dense aluminum oxide film. Its corrosion resistance is 2-3 times that of ordinary hot-dip galvanized steel, especially resistant to marine climate and industrial atmospheric corrosion.
2. Excellent High-Temperature Performance: Can be used continuously in high-temperature environments up to 315℃ (galvanized steel coils can only withstand 230℃), suitable for high-temperature working conditions such as chimneys and oven casings.
3. Longer Service Life: In outdoor unshielded environments, the service life of galvalume steel coils can reach 20-30 years, while that of galvanized steel coils is about 10-15 years, reducing long-term replacement costs.
4. Stable Processing Performance: The coating has strong adhesion and is not easy to peel off during bending, cutting, or stamping. It has good compatibility with coatings during subsequent spraying, preventing the coating from blistering or peeling.
5. Higher Cost-Effectiveness: Although the initial purchase price is slightly higher, the long-term use cost is 15%-20% lower than that of galvanized steel coils when considering corrosion resistance, service life, and maintenance costs.
