Pultrusion requires a slightly larger minimum material thickness than extrusion, about 3mm. To ensure an even distribution of the fibres, profiles are preferably manufactured with rounded corners.

1. Grooves e.g. for inserting sealing strips.
2. Colouring. Most types of plastic can be coloured. Where there are particularly demanding requirements for precise colours, pre-coloured granulate is used or a percentage of coloured granulate is introduced during the extrusion process.
3. Marking e.g. with barcodes, sorting declaration or company name, applied using ink jet printing.
4. Friction. High friction can be achieved through co-extrusion with a rubber-like thermoelast. This is used in architraves for example.
5. Sliding function. Some polymers have a very low friction co-efficient. These polymers can be used for durable products, e.g. for conveyor belts.
6. Screw pockets means that the profile has good attachment points regardless of the length to which it is cut.
7. Fixing. Guides and fixings can be designed so that the product only works within specific dimensional deviations. This enables extremely precise tolerance ranges.
8. Reinforcement using ribs at exposed places can be used to good effect instead of increasing the thickness of the material.
9. Insulating cavities in structures to counter cold bridges.
