Consistently high quality is the top priority for Lederer. This applies to the quality of both products and services.

All incoming and outgoing parts are subjected to a systematic quality analysis and assessment. Physical and chemical properties are examined with modern measuring instruments and compared with the desired properties. These permanent tests force our suppliers to deliver nothing but high quality products. Lederer does not cooperate with manufacturers that fail to maintain the required standard.

If there is an appropriate individual agreement with the customer, we can even carry out a 100% check, i.e. each individual part is subjected to a test before it is dispatched from stock. In this way, even unusual and extremely exacting quality requirements can be fulfilled.

In many branches of industry, moreover, fasteners with TÜV (German technical testing institute) approval are required. Lederer is one of the few suppliers whose product assortment depth now leaves hardly a wish in this area unfulfilled. The articles in question are given the designation „TÜV approved in accordance with AD-W2“ and the material specification „A 2-70 / A 4-70“ in the Lederer catalogue.

The following test certificates in accordance with DIN EN 10204:2004 can be issued:

At Lederer it goes without saying that as well as the quality of the products being tested, the quality of the services is clearly defined.

Quality management has been an established part of the company’s philosophy since 1993. Certification in accordance with DIN EN ISO 9001 (previously 9002) guarantees a high and precise standard in every business segment. This means that more than 98% of the products are ready for delivery and ensures that every work process is transparent for every employee.

Incidentally, the company’s most important capital (apart from you, the customers) comprises excellent specialized knowledge, permanent ongoing training and a pronounced customer orientation. Together, these comprise the trademark of the entire Lederer team.
The resultant quality awareness forms the basis of the successful long-term dialogue with our partners in the market. Not for nothing renowned large concerns classifiy Lederer regularly as a „preferred supplier“.

And not least, the installation of an environmental management system in accordance with DIN EN ISO 14001 and the observance of the > IMDS database (International Material Data System), developed by worlds major automobile manufacturers, speak for themselves and rigorously continue the path being followed.
