Fiberglass fabric is made of fine fiberglass strands and is super strong. Fiberglass cloth typically comes in large rolls, and is used for boat building, spot repairs and wood reinforcement. Fiberglass tape is great for filament windings, joining seams, and selective reinforcement. Fiberglass material also comes in a liquid or jelly resin as well. Zoro also has an outstanding selection of fiberglass grating, fiberglass sheets, fiberglass tubes, fiberglass rods, and fiberglass channels.
