Peninsula Iron Works has been a family owned company since 1946, when Gorge C. Johnson, a 20 year employee, entered into ownership as a stockholder. He directed and provided guidance to Peninsula Iron Works until his death in 1967, when his son Stuart B. Johnson assumed responsibility.  In 1993, Janet Johnson accepted the role of president while Stuart relinquished control of his shares to his sons; three generations representing nearly 70 years of service and leadership of the company. James Johnson now leads the business, along with his brother David Johnson, PE.

The Johnson family is passionately committed to keeping business local and keeping local workers employed. They prioritize employee safety, quality of products and projects completion while continually upgrading their equipment.  Their efforts to continually innovate and serve customers have continued to build Peninsula Iron Works into one of the premier machine shops in the United States.

Peninsula Iron Works partners with the customer to ensure that all projects meet or exceed requirements and provide the best possible value. Our in-house engineering and large selection of machinery allow us to work on both long and short term projects as well as all manner of unexpected downtime repairs for our customers. Our preventive maintenance service increases our “up-time” for our customers while improving machine life.
