During the early years, Kerkau was primarily a production machine shop, doing high volume jobs for the automotive and petrochemical industries. Forgings and castings were supplied from the customer and the finish machining performed by Kerkau.
As Kerkau began to grow, the company started purchasing A105 carbon steel raw forgings and began machining, marketing and selling the highest quality pipe flanges in the market under the Kerkau name. In the early 90's, after expanding the A105 product line to include up to 42'' NPS, Kerkau then added stainless 304/L and 316/L to the grades of material offered. With the Kerkau brand becoming more popular in the industry, in 2005, Kerkau began offering Long Weld Neck flange and was able to expand and build a 80,000 sq. ft sales office and finished goods warehouse. In 2012, Kerkau again expanded the product line to include A350 LF2 low temperature carbon steel, as well as another 80,000 sq. ft. warehouse facility.
Since its inception, Kerkau strives to keep these three core values:
- Exceptional Customer Service - without compromise
- Quality Products - never sacrificing
- Continual Improvement - how we thrive
