product inspections

All articles are subject to strict quality requirements and are therefore checked in detail on our premises by QS employees. Only after their OK, the products are added to the sales program.

For more safety...

we do part inspections on a random basis in our own testing laboratory. The parts only leave our warehouse

after 100 % of passing the test. This is what Metzger stands for.

For your and our safety - for sure!
