We are a

Good friend

In our relationships with our clients and stakeholders the joint profit takes the highest priority, but we are not yes-men. Consider us a ‘good friend’. This means we focus on long-term relationships and think in solutions, but also occasionally challenge each other if we see opportunities for different possibilities or room for improvement.

Everything can be done


We believe things can always be improved. That is why we continuously feed our innovation engine with ideas to be able to keep providing the best solutions for our clients and stakeholders – now and in the future.

How to interpret our product abbreviations

You have undoubtedly noticed the different abbreviations we use to describe our products. STF-WL, LDA 260 or HML; these are all kinds of shortcuts for interpreting the correct execution of the product. Since these abbreviations sometimes cause misunderstandings, we have written this blog post.
