1. Corrosion Protection:
Galvanized shingles are widely used in various environments due to their long-lasting corrosion protection, which varies depending on the environment.
2. Low Processing Costs:
Galvanized shingles offer lower corrosion costs compared to other coatings.
3. Durability:
4. Reliability:
The durability of the coating is highly reliable because the galvanized layer is metallurgically bonded to the steel, making it an integral part of the hard surface.
5. Toughness:
The galvanized layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use.
6. Comprehensive Protection:
All parts of the plated component are galvanized, including depressions, sharp corners, and hidden areas, ensuring thorough protection.
7. Time and Labor Efficiency:
Galvanizing is faster than other painting methods and eliminates the need for on-site painting after installation.
