    Quotes from Our Customers

    It’s no secret we’re the industry-leading solution that lasts. Here’s what our
    customers have to say.

    The main advantage of ZRC was that it allowed us to provide galvanized protection on site without delays to the project. Another important factor in specifying ZRC is its true cathodic action. With the volume of heavy traffic passing through the transit shed doors, it is likely they will be scratched. ZRC should provide zinc protection even when the doors are scratched to bare metal.

    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.

    The steel railings have held up very well, especially considering their constant exposure to the corrosive effects of moisture from Lake Erie and the Niagara River, the severe Buffalo winters, and the light road salting in the area.
