Talk to us. We Listen.

Tollenaar Industries is a – family owned – global supplier of industrial technologies. Our companies supply more than 3000 international customers with products and engineering services.

Our customer-base continuously presents us with new opportunities. To deliver; we develop our talent, adapt our organisation and create fundamentally new technologies.


As a young entrepreneur from Haarlem, the Netherlands, Frans Tollenaar founded Tubecon in 1970’s. The company started out in the production of sockets, bends, clamps and other tube related products.

Not impressed with the service-level of the local tube-manufacturer, Tollenaar decided to compete with the monopolist, and invested in a tube-mill. To ensure customer-focus, Tollenaar built the company on the principle: "Talk to us. We listen". Growth followed.


As a family owned, global supplier of industrial technologies, we believe our future still lies in the core principle of listening to our customers and adapting.

Each of our present (and future) companies will be built around the talent and skills of our people. There too, we believe the principle: "Talk to us. We listen" makes our companies an attractive place to work.

Simply stated: we will evolve and grow our people and our companies for generations to come.
