FRP weight calculator
Estimate fiberglass, carbon-fiber or basalt-FRP plate, rod and tube mass from geometry and density. Use the result for early material and freight screening before the supplier confirms product mass.
Dimensions and material
How the calculation works
The calculator converts dimensions to cubic meters and applies mass = volume × density. Hollow tube volume subtracts the inside cylinder. Grating and complex molded parts should use supplier-published mass per area or a CAD/production volume.
- Density presets are planning values, not product specifications
- Surface grit, coating, inserts and tolerances add delivered mass
- Long profiles may reach container volume limits before payload limits
- Use the approved supplier weight for purchase and shipping documents
