The Winona Advantage:
Powder Coat and E-Coat Under One Roof
Many manufacturers must work with separate suppliers for corrosion-resistant primer and durable topcoat applications. Winona is one of the few regional finishers offering both epoxy E-coat and powder coating, helping customers reduce supplier coordination, transportation between processes, and potential handling delays.
For parts exposed to especially harsh environments, an E-coat primer followed by a powder-coated topcoat can combine thorough corrosion protection with the color, finish, and exterior durability advantages of powder coating.
Capacity That Fits Your Program
From recurring high-volume production runs to low-volume specialty projects and large, heavy components, Winona has the equipment and floor space to adapt. Our Etna Green and Elkhart facilities provide more than 217,000 square feet of combined finishing capacity, with conveyorized lines, batch capabilities, automated application systems, and manual coating support where the part requires a hands-on approach.
Advanced Automation & Pretreatment Processes
Our Elkhart location includes two conveyor lines with five-stage washers, automatic and manual spray booths, and fast-turn options for select stock black and white finishes. This flexibility helps customers avoid choosing between speed, capacity, and finish quality.
Quality From Start to Finish
A coating performs only as well as the process behind it. Winona is ISO 9001:2015 certified for powder coating and E-coating of industrial, military, automotive, and agricultural metal parts, including pretreatment, parts drying, and coating cure. Additionally, we maintain a long list of other certifications and approvals.

Durable Coatings for Demanding Specifications
Your coating requirements may be driven by appearance, corrosion resistance, regulatory compliance, field conditions, or an industry-specific standard. Winona supports a range of demanding applications with AAMA-certified architectural powder coatings, MIL-spec and CARC coatings, UL-certified coating services for electrical components, and dedicated aluminum powder coating capabilities.
Whether you are coating architectural aluminum, agricultural equipment, automotive components, heavy castings, or industrial assemblies, our team helps match the coating system and process to the job rather than taking a one-size-fits-all approach.
Support Beyond the Spray Booth
Finishing is only one step in your production process. Winona can provide packaging, assembly, and delivery services that help protect finished parts, reduce internal handling, and make it easier to move components to your next operation or end customer.
Our team works with manufacturers to understand part geometry, material, volume, performance requirements, packaging needs, and delivery expectations before production begins. That practical, customer-focused approach helps prevent avoidable issues and keeps your program on track.
Frequently Asked Questions About Powder Coating
What is powder coating?
Powder coating is a dry finishing process used to protect and enhance metal parts. Electrically charged powder is applied to a grounded part, then cured in an oven, where it melts, flows, and bonds into a durable protective finish.
What are the benefits of powder coating?
Powder coating creates a durable finish that resists impact, moisture, chemicals, UV exposure, scratches, chipping, fading, and corrosion. It also gives manufacturers broad options for color, gloss level, texture, and other appearance requirements.
What materials can be powder coated?
Powder coating is commonly applied to heat-tolerant metal parts, including steel, aluminum, and cast iron. The part must be able to withstand the curing temperature required for the selected powder system.
What types of products can be powder coated?
Powder coating is used on a wide range of commercial, industrial, and consumer products, including automotive components, agricultural equipment, machinery, handrails, light fixtures, furniture, aluminum extrusions, and architectural components.
How does powder coating compare with conventional liquid paint?
Unlike conventional wet paint, powder coating is applied as a dry material and cured with heat. The process creates a thicker, more durable finish with strong resistance to wear and environmental exposure, while eliminating liquid paint solvents from the application process.
Does Winona offer custom powder coating colors and finishes?
Yes. Powder coating is available in a wide range of colors, gloss levels, textures, and performance formulations. Winona can help identify a finish that supports your appearance goals and your requirements for weathering, corrosion resistance, chemical exposure, or wear.
Why is pretreatment important before powder coating?
Pretreatment removes oils, soils, oxides, and other contaminants that can interfere with coating adhesion. Thorough surface preparation is essential to help the powder-coated finish bond properly and deliver dependable long-term corrosion protection.
Can powder coating protect parts from rust and corrosion?
Yes. Powder coating provides a durable barrier against moisture, chemicals, and other environmental factors that contribute to corrosion. For especially demanding service environments, manufacturers may also use E-coat as a corrosion-resistant primer beneath a powder-coated topcoat.
Can Winona provide AAMA-certified architectural powder coating?
Yes. Winona offers AAMA-certified architectural powder coatings for applications that require durable, specification-driven finishes, including architectural aluminum and other exterior components.
Can Winona powder coat high-volume production parts?
Yes. Winona supports high-volume finishing programs through its two Northern Indiana facilities, multiple powder coating lines, and experience serving OEM and Tier 1 manufacturing customers.
How do I choose the right powder coating for my part?
The right powder coating depends on the base material, part geometry, size, intended environment, corrosion and chemical-exposure requirements, UV exposure, required appearance, and applicable specifications. Sharing those details early helps determine the best pretreatment process, coating chemistry, and application method for your project.
Does Winona offer both powder coating and E-coating?
Yes. Winona is one of the few regional finishing providers that offers both powder coating and E-coating, allowing customers to select the right standalone process or combine E-coat primer with a powder-coated topcoat.
Contact Winona Powder Coating
We recommend powder coating since it outperforms conventional paint options in a variety of ways. Powder coating can cut down on finishing time, increase the quality of your finish, and open up a broader range of finishing options. It is a durable topcoat that will stand up against blazing sun and pounding rain. Our customers appreciate a finish that is wear and weather-resistant, but also easy to maintain. In addition to that, it is more environmentally conscious than conventional options because it doesn’t use harsh chemical solvents.
We are proud to serve the Midwest with our powder coating expertise.
