Namechange Gezu to RiZZ


On the 28th of October 2013 we rebranded our companies Gezu B.V. and KHZ Kunststoffen b.v. into RiZZ B.V. and RiZZ Plastics B.V. The activities of both companies will be merged under the brand RiZZ.

Over the past 72 years, various members of the Zuiddam family have contributed in their own way to the development of the company as you know it. The development and production of plastic products and brush applications are still central; but now we are a market focused company more than ever.

With this enhanced identity we want to emphasize our focus on sustainability, smart solutions and a high quality and service for our customers.

This new identity will bring about greater transparency and will give you a better insight on our activities. With all disciplines together we can increase our added value for our customers.



There is a lot of experience in the use of sustainable materials with many different applications.

The name RiZZ does not only represent who we are and what we do, but also reflects our commitment to further innovation. This shows from RiZZ | the entrance collection to the in-house developed windmill, but also in the continual aim on customer specific solutions. Due to this merger we will make better use of the family present competencies in the field of engineering, logistics and marketing.
