3M, located in Guin, Alabama, has been a mainstay in the Marion County community since 1955. What began as a cotton field and an initial building of 75,000 square feet is now a major manufacturing facility of over 500,000 square feet with over 300 employees. Their facility is part of 3M’s Traffic Safety and Security Division where they manufacture reflective road signs and pavement marking materials that are sold around the world. About 40% of the products made in Guin are exported to other countries. Reflective products are also manufactured for the Commercial Solutions Division for advertising on trucks & trailers and for improved visibility of emergency response vehicles. The Advanced Materials Division manufactures glass bubbles, a lightweight filler material for many markets, and ceramic microspheres, a filler material in paints and coatings.
