Years of experience have proven the benefits of hot dip galvanized protection. Galvanization protects steel in three ways:
- The coating weathers at a very slow rate giving a long and predictable life.
- The coating corrodes preferentially to provide cathodic protection(sacrificial) to any small areas of steel exposed through drilling, cutting or accidental damage. scratches are sealed by weathering products from the zinc.
- The sacrificial protection prevents the sideways creep of rust which can undermine paint coatings.
