With the manufacturer qualification according to DIN 18800-7, Class E, the so-called “Großer Eignungsnachweis” (major suitability qualification), it was confirmed at an early stage that we are qualified to manufacture demanding and safety-relevant steel structures.
The qualification level at the time included, among others:
- ✔ Dynamically loaded structures, such as crane runways and cranes
- ✔ Temporary structures, such as festival tents and amusement rides
- ✔ Working and protective scaffolding
- ✔ Structures made of high-strength and fine-grained structural steels
Although DIN 18800-7 has since been replaced by DIN EN 1090, this qualification remains an important testament to our extensive experience and expertise in structural steel construction.
The requirements of the former Class E correspond in many areas to today’s high execution classes EXC 3 and EXC 4.
Naturally, we also hold the relevant certifications according to DIN EN 1090 today.
For us, this certificate is far more than just a document. It represents quality, expertise, and responsibility – particularly when manufacturing demanding and safety-relevant steel structures.
