Below is a list of Fiberglass Fabricators manufacturers from 25lahoma-city, Oklahoma. Fiberglass fabricators manufacture shapes, products and materials that are composed of glass threads used as reinforcement agents. Fiberglass is made when molten glass is extruded through ultra-fine openings under high pressure and heat. This creates glass threads that are chopped, woven into a mat or spun to make wool. Fiberglass has a high strength-to-weight ratio and is scratch, chemical and temperature resistant.
