Which finish is specified for all gate hardware to prevent corrosion?

• A. Fabric coated
• B. Galvanized
• C. Malleable
• D. Wrought iron

Answer: (B)

Preventing corrosion on outdoor gate hardware relies on using a protective metal coating, and galvanized is the best choice. Galvanizing applies a zinc coating to steel, creating a barrier that blocks moisture and, if the coating is scratched, provides sacrificial protection because zinc corrodes before the steel. This makes galvanized hardware durable in rain, humidity, and salty or dusty environments commonly found around gates. It’s also a standard, cost-effective solution for outdoor components. The other options aren’t suitable finishes for corrosion resistance: fabric coating isn’t a metal finish for hardware, malleable describes a ductility property rather than a protective layer, and wrought iron by itself is prone to rust unless specifically protected, so it isn’t the reliable exterior finish galvanizing provides.
