Since 1984, Ashland-based Kar-Del Plastics has fabricated corrosion-resistant fiberglass-reinforced plastic and thermoplastic equipment for industrial applications. Its job-shop approach spans custom fabrication as well as nationwide installation, inspection, repair and modification work, including service on equipment made by other fabricators. The company also takes on unusual fiberglass projects, from a clamshell lemonade stand to a working model of the Marblehead Lighthouse.
