The USA INDUSTRIALS BULK-CS-GFR4-253 is a G-10/FR4 grade Garolite bar used in electrical, structural, and industrial fabrication applications. G-10/FR4 is a woven fiberglass fabric base material impregnated with a flame-retardant epoxy resin binder. This construction delivers high mechanical strength and solid electrical insulation properties. The bar measures 12 inches long, 4 inches wide, and 0.375 inches thick, weighing approximately 1.21 pounds. Its yellow color is standard for G-10/FR4 stock. Electricians, machinists, and industrial fabricators regularly work with this material when a dimensionally stable, electrically non-conductive structural component is required.
G-10/FR4 Garolite bar stock is used across a wide range of trades and industries. Common applications include electrical insulation panels, terminal boards, circuit board spacers, jig and fixture components, and structural supports in environments where moisture resistance and dielectric strength matter. This bar is sold as a single piece and is ready to cut, drill, or machine to fit residential, commercial, or industrial project requirements. It performs well in both dry and humid environments where standard plastics or metals are not appropriate.
Designed as a standard G-10/FR4 grade Garolite bar suitable for general electrical insulation, fabrication, and industrial applications requiring a fiberglass-epoxy laminate material.
G-10/FR4 bar stock is typically worked by machinists, electricians, or industrial fabricators using standard cutting, drilling, and milling equipment. Wear appropriate respiratory protection when cutting or grinding, as fiberglass dust is a respiratory irritant. Deburr all cut edges before installation in electrical assemblies. Verify material grade and dielectric requirements against applicable NEC or project specifications before use in live electrical panels or switchgear.
