Quotes from Our Customers
It’s no secret we’re the industry-leading solution that lasts. Here’s what our
customers have to say.
Because of my experience in the field with this product, I always recommend ZRC in corrosive applications. I've used ZRC to regalvanize radar towers and catwalk gratings for the Navy at the base in Winter Harbor, Maine. I also used it on metal roofs and on saltwater cookers at a canning company. In all cases, it has provided five years or more of rust-free protection.

We were amazed to find the structure in essentially the same condition as the day the building was dedicated" (26 years old). The ZRC had certainly done more than anyone expected in preserving and protecting the steel and welds.
Steve Anderson | Property Manager, Starr Realty, Inc
"I tried several inexpensive galvanizing topcoats, But that proved to be totally inadequate. In fact, they caused more problems beneath the surface of the coating. ZRC was an amazing transformation. My maintenance costs went way down. ZRC indefinitely extended the life cycle of the floats.
