Zinc Plating

Our barrel zinc line is a new state of the art 60″ barrel plater. At all times, it has the capability of processing zinc with clear chromate, yellow chromate, or no chromate without having any downtime in changing chromates.


We are continually working toward our goal of being QS9000 certified. Based on this, all chemicals that we use in processing are produced by ISO9000 certified suppliers.


In the near future, our plans are to add a batch bake oven. With it, we will have the capability to relieve hydrogen embrittlement. We are also looking into adding a rack zinc plating line in order to zinc plate large parts.
