About Us

Monroe is a ISO 9001:2015 & AS9100D certified global industrial manufacturing company offering a broad product line and has a diverse customer base of manufacturers, distributors and catalog-houses across several vertical markets including aerospace/defense, automotive, medical, transportation and many more. Monroe has a rich history dating back to the 1920s and Otto Siewek’s role in developing “tooling components”, which helped standardized mass production of automobiles.

Our Monroe team lives by a simple question, "How can we help?" Monroe has grown with so many customers because we were never afraid to help a customer attack an issue to get it solved correctly, quickly, and in an efficient manner. We continually expand our standard product offering based on the needs of our customers and have expanded our contract manufacturing capabilities to offer more custom solutions than ever before. Backed by a rock solid quality system our goal is to help you with your "problem of the day". Please give us a chance to earn your business.

Monroe Engineering Products is now OneMonroe!

The rebranding includes a name change and a visual refresh of the company’s logo and reflects Monroe Engineering Product’s growth in size and presence and marks a key milestone.
