FRP pultruded profile sizes
Standard pultruded FRP (GRP) profiles run from small angles and flats to deep structural I-beams and channels, in EN 13706 grades E17 and E23. The table below lists common sections with their dimensions, weight per metre and key section properties — all computed from geometry — and you can generate a render or datasheet for any custom size below.

How FRP profile weight is worked out
Pultruded FRP is roughly 1.9 g/cm³ for standard E-glass/polyester — about 30% lighter than aluminium and a quarter the weight of steel. Weight per metre is the cross-sectional area times that density, so once the section is fixed the weight is fixed. Note that published catalogue weights sometimes assume a slightly lower nominal density than pure geometry; Dimviz shows the computed engineering value alongside the catalogue figure so you can see the difference.
EN 13706 grades E17 and E23
EN 13706 classifies structural pultruded profiles by their full-section flexural modulus: E17 (17 GPa) and E23 (23 GPa). The grade drives stiffness and deflection, not the geometry — so the same 200×100 I-beam has the same area and section modulus in either grade, but deflects less in E23. High-fibre unidirectional rods reach 40 GPa and above.
From a size table to a datasheet
Pick any row, open it in the tool and you get a dimensioned drawing, an interactive 3D render and the full property set — area, Ix, Iy, Sx, Sy, radii of gyration, torsion and weight per metre — ready to drop into a spec sheet. Change a wall thickness and every number updates exactly.
FAQ
What sizes do pultruded FRP profiles come in?+
Common ranges: I-beams 76–305 mm deep, channels 38–360 mm, angles 25–152 mm legs, square/rectangular tube 25–240 mm, round tube 25–150 mm, rod 6–50 mm, and flat bar up to 305 mm wide. Custom dies extend these.
How much does FRP profile weigh per metre?+
Weight per metre equals cross-sectional area (mm²) × density (≈1.9 g/cm³ for E-glass FRP) × 0.001. A 120×60×6 I-beam is about 2.0–2.6 kg/m depending on nominal density.
What is the difference between E17 and E23 FRP?+
They are EN 13706 stiffness grades: E17 has a 17 GPa full-section modulus, E23 has 23 GPa. E23 deflects less under the same load; geometry and weight are unchanged.
