Estimate the weight of GFRP rebar by diameter, length, and quantity - useful for planning shipments and comparing against steel rebar weight.
This calculator uses the standard cylinder-volume formula (area × length × density) with a typical GFRP composite density. Actual weight varies slightly by manufacturer, resin system, and fiber content - confirm exact figures with your supplier for critical logistics planning.

How This Is Calculated
Weight per meter = cross-sectional area of the bar × 100 cm (1 meter) × composite density, using the standard cylinder volume formula:
Weight per meter (kg) = (π ÷ 4) × (diameter in cm)² × 100 × density (g/cm³) ÷ 1000
The "shipping class" shown is a rough weight-based grouping for planning purposes only (light / moderate / heavy load) and is not an official freight classification - always confirm actual freight class and rates with your logistics provider.
