Below is a list of Fiberglass Fabricators manufacturers from Erie, Pennsylvania. 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.
