Hot Dip Galvanizing for Wrought Iron Railings

The galvanizing process has been used to protect metal from corrosion for hundreds of years.  The process basically involves cleaning the metal then dipping it into a vat of molten zinc.  The multiple layers of zinc that form from this process prevent the underlying steel from corrosion even in salt laden ocean front environments.  The zinc does more than just coat the metal, it metallurgically bonds to it, actually becoming part of it.  These layers dissolve at a very slow rate (acting as a sacrificial layer) and without creating rust thereby providing decades of protection to the underlying iron work.

The level of protection is determined by:

1.      Coating thickness.  The thicker the coating the longer the life.

2.      The intended environment (geographical location) where the ironwork will reside. Enclosed pool areas, ocean front properties or close proximity to salted roadways all require a thicker coating of zinc. It's important to understand service environment when specifying a galvanized coating thickness.

Advantages of Galvanizing:

  • Relatively low cost compared to using nonferrous (non rusting) metals like stainless steel or aluminum.galvanized finish on cable railing
  • Low maintenance, coatings can last 25-50+ years.
  • Durable, scratch resistant.
  • Scratches or abrasions that compromise the coating are still protected by the surrounding zinc (galvanic cell).
  • Since during the hot dip process, the iron work is completely immersed in the molten zinc, the insides of tubing and interior crevasses of scroll ironwork get fully protected.
  • Can be painted or powder coated over the galvanized coating to enhance the beauty and add even more corrosion protection.

Disadvantages of Galvanizing:

  • It is difficult to control drips and sags and other surface imperfections so the resulting surface is not as fine (even after powder coating) as it would be if powder coated alone.
  • Galvanize dip tanks are limited in size which sometimes requires breaking up large sections of railing into smaller sections in order to fit them into the tank.
