Powder Coating for Agricultural Equipment and Components
Winona provides high-volume powder coating, e-coating and e-coat plus powder coating services for agricultural equipment manufacturers and suppliers. Our capabilities are designed to accommodate small to large agricultural components, including castings, fabricated parts, assemblies and components with challenging geometries or varying metal thicknesses.
More importantly, we understand the unique finishing challenges you run into with ag equipment: corrosion requirements, cast substrates, film-thickness control, cure requirements, pretreatment, downstream machining, and demanding OEM specifications. We’ve spent decades building the equipment, processes and technical expertise to solve them.


Powder Coating for Large Agricultural Parts and Heavy Equipment
Large agricultural components at production volumes require more than just a large powder booth. The entire finishing system must be capable of properly pretreating, coating, curing, and handling the parts.
As you’ve probably dealt with, everything becomes more challenging as the size and metal mass of a component increases. A substantial casting takes considerably more time and energy to reach the required part-metal temperature than a thin fabricated component.
When enough cold metal enters an oven, the parts themselves absorb tremendous amounts of heat. Winona specifically designed one of our powder coating lines with the capacity and curing power to handle the challenge:
- Our approximately 1,000-foot-long system includes a 135-foot cure oven with 7.2 million BTUs of burner capacity.
- The system gives us the flexibility to process a broad range of agricultural components while providing the heat capacity and cure control required for larger or higher-mass parts.
- A long cooling section also provides components adequate time to cool before unloading and packaging.
Winona is proud to serve as one finishing partner that can accommodate a wide range of component sizes within ongoing production programs while maintaining the process control required for precisely consistent coating quality. Our versatility is a huge reason why we’re a leading coater for ag equipment throughout the Midwest and nationwide.
Proper Curing Is Engineered into Our Process
Powder coating cure isn't simply about setting an oven to a particular temperature. What matters is whether the metal itself reaches and maintains the powder manufacturer's specified cure temperature for the required amount of time. That's an important distinction for agricultural components.
A thin steel fabrication may reach temperature relatively quickly. A casting or component with greater metal mass takes considerably longer. Assemblies incorporating different metal thicknesses can be even more challenging.
Our technical team and equipment allow us to develop oven profiles around the actual component rather than relying solely on oven temperature. Low-cure powder technologies can also provide additional options for certain applications, allowing proper cure at lower part-metal temperatures while potentially improving throughput.
The result is a coating process developed around the part, substrate and specification, not a one-size-fits-all oven setting.
Solving Agricultural Coating Problems and Challenges – 50+ Years of Experience
Some of the most challenging agricultural components aren't necessarily the biggest. A component may combine different metal thicknesses, contain difficult geometries, require tight film-thickness control, or have a demanding corrosion specification.
For example, Winona produced a component for a large agricultural components customer that combined a relatively light aluminum extrusion with a much heavier aluminum casting. The challenge was getting the casting to the required cure temperature without overheating the thinner extrusion.
Winona developed a repeatable process and successfully coated the component. That's the kind of finishing problem our technical team is equipped to solve. We evaluate variables including:
- Substrate and part geometry
- Metal thickness and mass
- Pretreatment requirements
- Powder chemistry
- Film thickness
- Oven profile and part-metal temperature
- Cure requirements
- Racking and grounding
- Masking
- Downstream machining
- Packaging and handling
You don't have to be an expert in powder coating or e-coating to bring us a difficult finishing problem. That's our job
E-Coat + Powder Coat for Agricultural Corrosion Protection
For agricultural components exposed to moisture, chemicals, fertilizers, abrasion and harsh outdoor environments, manufacturers may need more corrosion protection than a single coating layer can provide. Winona offers e-coating and powder coating under one roof, including systems that use epoxy e-coat as a corrosion-resistant primer beneath a durable powder topcoat.
E-coat provides excellent coverage of complex geometries, recesses, and difficult-to-spray areas. The powder topcoat adds another protective layer while providing the color, appearance, UV resistance and durability required for the finished component.
Depending on the coating specification and system selected, e-coat plus powder can significantly increase corrosion resistance compared with powder coating alone. Keeping both processes within one finishing operation also reduces transportation, handling, and coordination between separate coating suppliers.

Does Winona Powder Coating coat agricultural equipment components?
Yes. Winona provides production powder coating and e-coating for agricultural equipment manufacturers and component suppliers, including steel, aluminum, cast iron and cast aluminum parts.
Can agricultural components be e-coated and powder coated?
Yes. E-coat can be used as a corrosion-resistant primer beneath a powder topcoat when the coating specification calls for increased corrosion protection, coverage in complex geometries or a two-coat finishing system.
Can Winona coat cast iron agricultural components?
Yes. Winona has experience controlling cure and powder film thickness on cast components, including parts that may require machining after coating.
Can Winona coat both small and large agricultural parts?
Yes. Winona's production equipment accommodates a broad range of component sizes. Our approximately 1,000-foot powder coating system includes a 135-foot cure oven with 7.2 million BTUs of burner capacity for components requiring substantial curing capacity.
Why does part-metal temperature matter in powder coating?
Powder must cure according to the coating manufacturer's specified time and part-metal temperature. Larger castings and components with more metal mass generally take longer to reach that temperature, which is why oven profiling and curing capacity matter.
Where does Winona provide agricultural powder coating services?
Winona Powder Coating operates facilities in Etna Green and Elkhart, Indiana, serving agricultural and industrial manufacturers throughout the Midwest and beyond.
