The Manufacturing Process of Highway Signs
Highway signs are essential for guiding drivers on American roadways, and their manufacturing involves a detailed and precise process. A significant portion of these signs, especially large guide signs, are produced at a plant in Bunn, North Carolina. Workers begin by cutting large aluminum sheets to size, which can be as large as 12 feet long, and then applying reflective sheeting to ensure visibility at night. The production process can take around 12 hours for a single sign, demonstrating the intricate and labor-intensive nature of creating these critical public safety devices.
