Hot Dipped Galvanized

Black Iron vs. Galvanizing

Goldline offers our products in black iron like this Craddle Style Hose Handler or Hot Dipped Galvanized. The time for first maintenance of steel with (HDG) Hot Dipped Galvanizing is often years or decades. That distance is in time, measured by the thickness of the zinc coating in the clean galvanizing process.

The chart below shows 5.0 galvanizing zinc coating thickness can produce up to 98 years of very low finish maintenance." Goldline highly recommends hot-dipped galvanized.
