Quality and Dedication

We have been using Giering Metal Finishing to coat our products since August of 2005. Over the last 15 years, Giering has finished over 50,000 parts of ours. Their quality and dedication have been so good over the years that I have not even considered another vendor to coat our products. They are one of my most loyal and dependable vendors. I honestly do not believe we have ever had an issue with one single part. From quoting to processing to pickup and delivery they are committed to their customers.


Dependable Supplier and Partner

Giering Metal Finishing has been a dependable supplier and partner for two generations. They have worked closely with us to develop customized finishing solutions to meet our requirements, including military specifications. Their work is predictable, and their team takes an active role in problem-solving when difficulties arise.


Quality of Work

We have been using Giering for over 30 years.  The quality of work, competitive pricing, customer service, and quick turnaround are why we keep coming back.

Turnaround Times are Outstanding

As a family-owned and operated business ourselves, we are fortunate to have discovered Giering Metal Finishing nearly 20 years ago as our e-coat finishing needs grew.  What I love about Giering is how accessible and responsive they are.  Turnaround times are outstanding, and the attention to detail is evident, whether it’s in the quotation process or in the product finish.  They have earned their place as one of our most dependable suppliers, and it’s nice knowing that I can pick up the phone at any time and get prompt answers to anything that comes up.  The owners are very involved in day-to-day operations and it shows.


Timely, Thorough, Honest In-depth Analysis

I have been working with Giering Metal Finishing for over 5 years now. My primary function is with New Product Introduction. When we have a new color, a new type of coating, or a new type of assembly that needs coating, Giering is my go-to source. I know I can depend on the owners and staff at Giering Metal Finishing to give me a timely, thorough, honest in-depth analysis of the situation. Their level of expertise and professionalism is unsurpassed. Their recommendations are always spot-on, and when it comes time for trial runs their quality and on-time delivery are impeccable, which are carried through to production runs.

Price Competitive, Quality-Oriented

We have had a business relationship with Giering Metal Finishing for 16 years.  We chose Giering because of their expertise in Powder Coating and the family approach that they demonstrated over the years.   As a result of this approach, Giering is very adaptable to our needs which is key to satisfying our customer base. Giering is price competitive, quality-oriented, and has provided technical assistance to Solid State when needed.  I would highly recommend Giering Metal Finishing to anyone that has a need for their offerings.
