Rack Zinc Plating of a Steel Pump Flange for a Local City Project

A local customer commissioned for a local city project contacted Commercial Electro Plating to perform zinc plating on the steel pump flange as highlighted here. The treatment would extend part life and protect from premature rusting. This 4′ x 3′ unit is large for typical zinc plating operations, but posed no problems for our company. The proper cleansing and prep work was performed, and parts not requiring treatment were masked for protection. The part was plated on our rack line where a 0.001″ – 0.002″ tolerance was maintained throughout. The specifications called for a type 5 process, administering a clear chromate finish for enhanced appearance and protection.

Two units were plated and delivered to the client in Fresno, California after a turnaround time of 2-3 days. Dimensional and visual inspections were administered to assure quality. We are able to plate to both ASTM and Military standards, offering different finishes and thicknesses as customers require.
