Galvanized steel undergoes a process where a protective zinc coating is applied to steel to prevent corrosion. This coating enhances the steel's durability, making it resistant to rust and corrosion even in harsh environments. Commonly used in outdoor structures, roofing, fencing, and automotive parts, galvanized steel offers long-term protection against the elements while maintaining its strength and structural integrity. Its versatility and cost-effectiveness make it a popular choice across various industries for both decorative and functional purposes.
