About EIW, LLC

Eagle Iron Works has been in operation since 1872. For over 140 years, they have served the aggregates industry and remain a leader in this market today.

Founded in 1872 by brothers George and Lawrence Aulmann, EIW was originally located on Court Avenue in Des Moines, Iowa. In the early 20th century, the company moved its operation to Holcomb Avenue and has operated there ever since.



Ted Aulmann, son of George Aulmann, managed the business through the great expansion in the 50's and 60's. In the early 1960s, Ruth Aulmann, daughter of Ted, married Andrew Krantz. Krantz began working at Eagle Iron Works and in 1972 took over as company president.  He continued to manage the business until 2011, when he retired at the age of 97 years old. 

In November of 2012, McLanahan Corporation purchased the assets of Eagle Iron Works under EIW, LLC. McLanahan plans to continue the long history of excellent product durability and quality for which EIW has become known, while incorporating McLanahan’s fine traditions that have sustained them since 1835. McLanahan is proud to have added Eagle Iron Works to its family of companies.
