At Giering Metal Finishing, our cleaning and conversion coatings services provide the critical foundation for superior metal finishing. These processes enhance the durability, corrosion resistance, and overall performance of metal components, ensuring they meet the highest standards in quality and longevity. From automotive to aerospace, we work with a wide range of industries to deliver precision results tailored to your needs.

What Are Cleaning and Pretreatments?

Cleaning and pretreatment for coatings involve the preparation and treatment of metal surfaces to improve adhesion, prevent corrosion, and optimize the finishing process. By cleaning and pretreating the surface, we ensure that coatings such as paint, powder, or e-coat adhere properly and perform effectively. Conversion coatings, such as phosphating, provide an additional layer of protection by chemically altering the surface to enhance its resistance to rust and wear.

Substrates We Work With

We specialize in working with a diverse range of substrates to ensure optimal coating performance. Each material requires a unique approach to achieve the best results, and our expertise ensures flawless finishes tailored to your product’s needs.

Aluminum: Lightweight yet durable, aluminum benefits from corrosion resistance and adhesion through tailored pretreatment and coating processes.

Cold Rolled Steel: Known for its smooth surface and strength, we ensure precise coatings that protect and enhance its durability in demanding applications.

Stainless Steel: Resistant to corrosion and wear, our specialized coatings further extend its longevity and enhance its aesthetic appeal.

Castings (Aluminum, Zinc, Iron): We expertly handle cast components, providing finishes that accommodate complex geometries while ensuring longterm performance.
