Stay Connected with Adams-ISC

Welcome to Adams-ISC, LLC. a Subsidiary of ISC Companies

Branch Locations About Page PictureAdams-ISC in Rapid City was formed in 2011 as a merger between Adams Machining & Welding in Rapid City and ISC Companies in Minneapolis. Adams Machining & Welding was formed in 1982 with a vision of providing the best possible service to companies needing custom parts and service. ISC Companies, formerly Industrial Supply Co., was incorporated in 1939 with the determination to “Become the foremost distributor of power transmission equipment and factory supplies in the entire Midwest”.

At the time of the merger, it was determined that the “Adams” name was well-established and had a positive long-standing reputation throughout the region. Changing the business name entirely would put that recognition at risk. The solution was a name combination to form Adams-ISC, where both brands are represented and the Adams identity continues to live on and build on its strong history.
