Not just any old Zinc

Hot-dip galvanizing isn’t just painting or spraying on a coating of zinc. We use acids to prepare the metal, then dip it in molten zinc. The result chemically bonds the zinc to the steel. Durable for decades, with no maintenance. And we offer it in three grades:

Grade B – Best for material encased in concrete such as rebar.
Grade A – Ready to assemble and meets ASTM123a specifications. Typical for structural steel components.
Grade AA – No sharp edges, suitable for hand rails or any item that will be handled.


Our products meet or exceed all state, federal and ASTM standards. They’re two-thirds the cost of a three-part paint system and we warranty our work for 20 years.

Also for your benefit

  • We operate 24 hours a day, 365 days a year in a factory controlled atmosphere to meet our customer’s needs.
  • We offer while-you-wait service for no additional charge. Please call ahead to schedule this service.
  • We have pick-up and delivery service.
  • Our quotes are timely, and we offer written certifications and warrantees, citing specific life expectancy.

  • We can do custom tags if required.

Proven Technology

Galvanizing is not new; it’s a proven technology with more than 250 years of effective application. And that technology is based on observations that date back 2,000 years.

But that doesn’t make every kind of galvanization equal. Hubbell Galvanizing provides hot-dip galvanizing, or HDG. We prepare metal in a series of acid baths, then dip the metal into molten zinc – heated to nearly 850 degrees Farenheit.

The result is galvanization that protects the core metal two ways:

  • The zinc coating provides a tenacious barrier that prevents moisture and corrosive agents from attacking the steel.
  • The zinc actually sacrifices itself first – cathodically -- oxidizing before the steel can oxidize.
  • The combination provides an extremely long protection for steel products. Longevity estimates, based on thickness of zinc, are categorized according to atmospheric environment, in order from gentle to harsh:
  • Rural.
  • Suburban.
  • Temperate Marine.
  • Marine.
  • Tropical Marine.
  • Industrial.

ASTM A 123, the standard governing HDG, is 3.9 mils for quarter-inch material. So a new product placed in a suburban environment can be expected to last at least 95 years.
