Our solutions

Perforation catalogue

Every pattern in our catalogue corresponds to existing tooling, available immediately with no development costs. And if you cannot find your pattern, we will make it: that has been our business since 1899.

Find or create your pattern

Have a specific pattern in mind?

The detailed list of patterns available from our tooling (shape, section, open area) is being updated. In the meantime, send us the reference you are looking for: we will confirm whether it already exists in our tooling, with no development costs.

Your pattern does not exist yet?

We design and machine our tools in-house. A new geometry, a particular pitch, a decorative pattern taken from your drawing: tell us the function you need and we will tell you what can be done, at what tooling cost and in what lead time.
