INDUSTRIES SERVED

Winona Powder Coating has spent more than 50 years solving corrosion, durability, and appearance challenges for manufacturers across a wide range of industries.

Our experience ranges from heavy castings, machine shop components and aluminum extrusions to architectural coatings, EV battery applications and data center jobs…among many other industries.

No matter the application, we always match the right powder coating, E-coating, or combined E-coat/powder-coat application to each part's service environment and specification requirements.
