About Jack Frost Ironworks
From The Beginning
Jack Frost Ironworks (JFI) has been a family owned business for over 50 years. Knowledge and experience were passed down from generation to generation starting with Jack’s grandfather, Karl Frost, who arrived from Hamburg Germany in 1910 at the age of 23. Karl became an ornamental ironworker and passed down his skills to his twin sons Carl and Bill. The Frost family worked for Ralph H. Simpson for years. The sons of Carl and Bill kept these skills in the family and started their careers there also. Jack brought his knowledge and experience in this field to northern Illinois where he, with the help of his wife Dee, started Jack Frost Ironworks from scratch. In 1975 Marriott Great America, now known as Six Flags, hired JFI for their miscellaneous metal fabrication. At that time the company grew with the hiring of its first two employees.
The name Jack Frost Ironworks was spread by word of mouth and their business began to flourish. In 1977 after joining the Lake County Contractor Association, JFI became a well-known steel fabrication business in northern Illinois. Jack and Dee's two daughters Deborah and Jacque, son-in-law Jim, and long-time employee Steve Haas, continue to make this small family business a success today.
The key to our success is teamwork and communication with our valued employees. JFI fabricates in house and subcontracts field installation with union ironworkers. Here at Jack Frost Ironworks, we take pride in our craftsmanship and we stand behind our work.
