What happens if the galvanized coating is damaged
during use?

If the galvanized coating is physically damaged, it will continue to provide cathodic protection to the exposed steel. If individual areas of underlying steel or iron become exposed as much as 1/4", the surrounding zinc will provide these areas with cathodic protection for as long as the coating lasts.

How adherent is the galvanized coating?

The galvanized coating is adherent to the underlying steel on the order of several thousand pounds per square inch (psi). Other coatings typically offer adhesion rated at several hundred psi at best.

Are galvanized materials more prone to damage at
the corners or edges?

The galvanizing process naturally produces coatings that are at least as thick at the corners and edges as the coating on the rest of the article. As coating damage is most likely to occur at the edges, this is where added protection is needed most.  Brush- or spray-applied coatings have a natural tendency to thin at the corners and edges.

What happens when hollow materials are galvanized?

Because the galvanizing process involves total immersion of the material, it is a complete process; all surfaces are coated. Galvanizing provides both outside and inside protection for hollow structures.

How long does it take to have materials galvanized?

The galvanizer’s ability to work in any type of weather allows a higher degree of assurance of on-time delivery.  Working under these circumstances, galvanizing can be completed quickly and with short lead times. A turnaround time of two or three days for galvanizing is common.
