The quality of BETESO products plays an outstanding role in this. For BETESO, quality means much more than just delivering an outstanding product. High-quality materials and, above all, qualified and motivated employees throughout the company are decisive for the manufacture of a good product.

BETESO’s high standards begin with product development. Highly trained employees with a lot of experience develop our products – on request also individually for our customers. BETESO can offer state-of-the-art products at any time through regular further training of its employees.

Together with you, we define which standards your project must comply with. Of course, we also request these from our suppliers.

The passion with which BETESO works from the first meeting with the customer to the delivery of the finished product is also evident in production. Selected production partners – mostly from the region – manufacture the products in close cooperation with BETESO. Continuous control of production and comprehensive quality management are a matter of course for BETESO.

This ensures the high quality of BETESO in every production step. Whether according to ISO 9001, ISO 13485 or ISO/TS 16949 and compliance with ISO14001, our partners can do it.

Efficient administration and competent employees in development, purchasing, sales and logistics ensure smooth processes throughout the entire company.

All BETESO employees face up to the high quality standards of our products on a daily basis. BETESO has been convincing its customers with this claim since 1996 – and is proud of the motivation and willingness to perform of all employees in the company.
