Laminated FRP Sheet Technical Data Sheet
Fiberr USA Fiberglass-Reinforced Plastic Sheet and Panel
Product Overview
Fiberr laminated fiberglass-reinforced plastic sheet is a lightweight, durable, corrosion-resistant material manufactured with fiberglass reinforcement and thermosetting resin. It is available as continuous coil or cut panels for wall lining, transportation, cooling-tower cladding, industrial enclosure, architectural, and OEM applications.
Sheet construction can be configured with different thicknesses, reinforcement layers, surfaces, backside treatments, colors, resin systems, fire-retardant formulations, and UV-protective options.
Manufacturing range: Fiberr can manufacture laminated
FRP sheet from approximately 0.039–0.197 in (1–5 mm) thick and in widths
up to approximately 116 in (2,950 mm), subject to the selected
construction, reinforcement, surface, and application.

Approximate Sheet Weight Calculator
Calculate Approximate Areal and Total Weight
Enter the sheet thickness to calculate approximate weight per unit area. Width and length are optional and can be entered to calculate the approximate total weight of a panel or coil.
Manufacturing range: 0.039–0.197 in (1–5 mm)
Approximate Metric Areal Weight
3.77 kg/m²
Approximate Imperial Areal Weight
0.77 lb/ft²
Approximate Total Weight
Enter width and length
Calculation basis: Approximate weight in kilograms =
1.65 × thickness (mm) × width (m) × length (m). Therefore, approximate
areal weight equals 1.65 × thickness (mm) in kg/m².
General guidance only: The values and calculated weights
shown on this page are approximate and may vary with actual thickness,
resin composition, fiberglass type, fiberglass content, reinforcement
configuration, surface veil, gel coat, embossing, fire-retardant additives,
color, manufacturing tolerances, moisture content, and other product
construction variables. Confirm final dimensions, properties, and shipping
weights for the specific product configuration before design, fabrication,
procurement, or freight planning.
