Although the paint industry has made great improvements in paint systems HDG is still superior to paint for corrosion protection providing decades not just for years. Here’s why:
• HDG is not just a coating like paint. HDG metallurgically bonds zinc to the steel.
• In addition to the metallurgical bond HDG provides two other types of protection - Cathodic Protection and the Zinc Patina. Paint does not provide these extra protections.
• Despite improvements in paint in recent years the most serious drawback of paint systems is that if the coating is damaged and bare steel is exposed it will immediately begin to corrode. As the rust increases it grow under the remaining paint coating separating it from the steel and causing the paint to flake, then peel off. As the paint peels more steel is exposed and the corrosion grows in all directions under the paint causing more and more paint to flake and peel off. The paint system fails. Repair to paint can be expensive, difficult to make, hard to remove the rust from the surface and harder still to verify that the surface was prepped and painted properly for the new paint to stick
