Domestic Finishing for Class 3 through Class 8 Truck Parts

Work truck parts have to handle tough duty. Frames, brackets, bodies, racks, and accessories face road salt, moisture, gravel, chemicals, UV exposure, vibration, and daily abuse.

Winona combines quality certifications, high-capacity finishing, and both powder coating and E-coating to help protect those parts and deliver them where and when you need them.

Finishing Built for Commercial Truck Manufacturing and OEM Programs

Commercial truck programs depend on consistent quality, predictable delivery, and suppliers that can scale. A coating partner needs to meet specification, handle large production volumes, and adapt to changing schedules without sacrificing finish quality.

Strong corrosion protection for road salt, moisture, and outdoor service
Durable finishes that resist chipping, abrasion, and gravel impact
UV-resistant powder coatings for long-term appearance
Complete coverage on complex welded and formed parts
Certified quality systems for OEM and supplier programs
High-volume capacity for recurring production
Custom masking and handling where required
Dependable delivery and quick turnaround

Winona works with truck OEMs and suppliers to review material, part size, geometry, corrosion exposure, appearance requirements, specification, and volume before production begins. Our goal is to make reshoring your finishing operations simple.

Powder Coating for Durability and UV Protection

Winona applies durable powder coats for a tough, lasting finish that stands up to hard work: abrasion, chipping, scratching, chemicals, and sun exposure. It’s the default choice for work truck components that need long-term appearance and protection in rugged service conditions.

A durable, protective exterior finish
UV protection and color retention
Resistance to abrasion, moisture, UV and chemical exposure
Consistent appearance across production runs
Strong edge and surface coverage
A low-VOC alternative to conventional liquid paint

Powder coating offers broad color, gloss, and texture options, making it useful for visible truck bodies, accessories, and branded fleet equipment as well as functional structural parts.

E-Coat for Corrosion Resistance

Our E-coating immersion process gives excellent corrosion resistance with comprehensive coverage, reaching recesses, tight corners, and complex features that can be difficult to cover with spray application.

Uniform coverage with controlled film thickness
Strong corrosion protection on welded and formed assemblies
Coverage on brackets, crossmembers, frames, and hollow sections
Efficient processing for high volumes
A standalone functional finish
A corrosion-resistant primer beneath powder coating

Winona's E-coat line includes a 13-stage pretreatment process with laser scale removal, zinc phosphate, and RO water. Automated indexing helps reduce air-pocket effects as parts enter the tank, supporting consistent coverage.

E-Coat Primer + Powder-Coated Topcoat

The ultimate part protection is an E-coat primer paired with a powder topcoat. That combination is hard to find at other parts finishers.

The E-coat protects the entire surface of the part, including hard-to-reach areas, while the powder topcoat adds durable UV protection, color, and abrasion resistance. If the powder is chipped or scratched by gravel, tools, or daily use, the E-coat underneath continues to protect the metal from rust and chemical corrosion.

This layered system is well suited to work truck frames, accessories, and structural parts that face road salt, moisture, and heavy-duty service.
