GRP-profiles are manufactured using the pultrusion process (from “to pull”). This production method is characterized by a continuous manufacturing process of consistently high quality. The glass fibers used to reinforce the profiles are pulled through a guide head and then through a heated tool. In the tool, the fibers are impregnated with the resin mix and cured by heating to the desired geometry.
The profiles are produced in a continuous process and are cut to size directly after pultrusion. The common standard lengths are 6,000 and 12,000 mm – other lengths are also possible depending on quantities.

We offer you a wide selection of GRP-profiles for a wide range of applications. The following table shows an overview of all available variants.
Note: Items marked with * are available directly from stock.
| Minimum distance | e | c | P1 | P2 |
| Load in longitudinal direction of the profile | 2.5 ds | 2 ds | 4 ds | 4 ds |
| Force perpendicular to the direction of pultrusion | 2.5 ds | 2 ds | 4 ds | 4 ds |
ds = screw diameter
dL = hole diameter
| Ring/screw | M8 | M10 | M12 | M16 | M20 |
| ds (mm) | 8 | 10 | 12 | 16 | 20 |
| Outer diameter of the washer | The washers must have a particularly large diameter of at least 3.4x ds. | ||||
| MA (Nm) | 16,8 | 33,2 | 59 | 141,2 | 275,3 |
| FV (kN) | 11,1 | 17,48 | 26,24 | 47,07 | 73,42 |
| Outer diameter of the washer | Washers with a diameter of at least 3.0 x dS should be used for screw connections that are only used to secure the position. | ||||
| MA (Nm) | 5,73 | 11,6 | 20,9 | 50,7 | 98,6 |
| FV (kN) | 3,78 | 6,09 | 9,28 | 16,91 | 26,3 |
The following hole clearance must be maintained between the screw diameter and the hole diameter:
| M8 to M16 screws: | dL – ds ≤ 1.00 mm |
| M20 screws: | dL – ds ≤ 2.00 mm |
