Connecting ideas to reality

Dutch Innovation Systems is the inventor and manufacturer of the patented Topclamp construction systems. As innovative productdevelopers and manufactures of high-end reuseable construction systems, we strive to connect design, sustainability, simplicity and bespoke requirements to offer the perfect solution to our customers frame-related needs.

Our vision

Topclamp products have a premium quality

The clean lines and elegant design of the components highlight your products or presentation without distracting your visitors attention. By choosing the right finish, the look of your structure can be changed from understated to eye-catching. The distinctive, clean design of our products set your structure apart in comparison to the usual, old widely used construction methods.

Our systems are purposefully designed

The design of the joints make the positioning self-evident. The connection direction and position in the assembly are also clearly documented in well defined drawings, making assembly and disassembly child’s play. Due to the simplicity, expensive technical personnel are not required, assembly or disassembly of Topclamp structures can be done by anyone. By delivering the structures complete in kit form it allows larger structures to be carried out in tight spaces with limited access due to doorway restrictions.

We make our own components

We make our components from single materials which allows for very efficient recycling, the few components made from more then one material have been designed to be easily separated for recycling.

Almost all our components are made from aluminium. These are alloys with exellent recyclability that can be recycled time and time again without loss of properties.


We aim to offer individual solutions for your framework-relateded needs

By taking your requirements into account we can offer the right Topclamp product, make customisations to our products or offer completely custom specially designed components or systems.


Dutch Innovation Systems originated from the Metaalwinkel, a metal wholesaler in Rotterdam (the Netherlands).

Metaalwinkel owner Adriaan Maris had been a succesfull business owner of several companies when he had the idea of creating Topclamp joints for a wide array of applications.

In 2013 Ronald Boertje was hired to develop Topclamp products for sale on a small scale through the Metaalwinkel’s own outlets..

In 2019 the company Dutch Innovation Systems was founded with both Adriaan Maris and Ronald Boertje sharing ownership. Dutch Innovation Systems continued developing and producing new innovative systems as well as creating custom solutions for high-end customers around the world.

In 2022 Dutch Innovation Systems will be moving to a brand new, environmentally friendly, headquarters in Barendrecht, increasing it’s capacity and recourses to further grow the company.

We are moving

Our new, purpose-built building is due to be ready at the end of August 2022.
We will have beter showroom facilities and more working space to produce Topclamp products on a greater scale than at present.
We will be happy to discuss your projects in our new, airconditioned meeting rooms.
