uncompromisingly high quality

Our quality standards are uncompromisingly high!

Therefore, KLETT Metalltechnik GmbH is certified according to DIN EN ISO 9001.

All individual operations are stable and documented reliably.

In addition we possess the constructor´s welding qualification
according to DIN 18 800 - 7 class E and C

Description of constructor´s qualification E:

A measure of the recognition given to us is the constructor´s qualification class E according to DIN 18800-7 (comprehensive qualification certificate with extension for loads which are not predominantly static) for steel structures.

This means, there is no limit concerning thickness or span of the sheets to be welded as it is the case with companies only owing a constructor´s qualification class B or C. We are also approved for welding work at so called loads which are not predominantly static  e.g. railway and road bridges according to guideline 804 and DIN textbook 103 and 104.

The constructor´s qualification includes components according to DIN 4132 craneways steel structures, DIN 4420 service and working scaffolds, DIN 4112 temporary structures and DIN 24117 construction equipment and building material machinery distributing mast for concrete.

A constant training and continuing education for our staff is a matter of course for us. We highly value self-motivated, responsibly minded employees!

guaranteed quality - in all stages of production

Constantly highest quality - this is what KLETT stands for. Wherever highest quality standards are required - KLETT does not only constantly check its quality we also produce it.   

We control the components in every stage of production. Only by this, all design guidelines can be collected and observed.
