Weight calculator
Estimate shipping and material weight before you ask for a quote. These are estimates from your inputs: real weights vary with tolerance, sizing, resin content and packaging.
Fabric roll
Formula: weight (kg) = areal weight (g/m²) × width (m) × length (m) ÷ 1000. Excludes the core tube and packaging.
Round tube
Formula: volume = π ÷ 4 × (OD² − ID²) × length; weight = volume × density. Density depends on fiber, resin and fiber volume fraction, so take it from the data sheet of the exact product. Ask us if you do not have one.
