Kerkau uses A105 carbon steel raw forgings and began machining, marketing and selling the highest quality pipe flanges in the market under the Kerkau name. 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.
