Products & Services
WE USE SPECIAL HIGH-GRADE ZINC THAT IS LEAD FREE AND 99.999 % PURE
Hot-dip galvanizing offered 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 & Here-today-gone-tomorrow (expedited) services pending current workloads and prior commitments.
- Our quotes are timely, and we offer written certifications and warrantees.
- We offer metal tags that survive the galvanizing process at no additional cost to your galvanized job. If you would like custom tags with specified part number tags OR rebar tags printed in advance of the job for your own facilities tagging for identification we can help you through the process of providing us a list that we can print the tags from and either send with your driver back to your facility or ship them directly to you.
Not just any old Zinc
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:
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.
