Perfection to detail is the key to a precise whole.

That principle has consistently remained the company philosophy ever since it was first founded in 1950.
Hans Berg GmbH & Co. KG is an internationally operating manufacturer of deep-drawn and metal tube components for a vast diversity of industries. The group has sites in Reichshof, Germany (headquarter), Florstadt and Dilovasi/Istanbul (Turkey) employing roughly a staff of a staff of 600 people and specialising in cold-forming, joining, threading and cutting tool technology. Berg is the technological and market leader in the field of fittings and connections for radiators and convectors. Other important business sectors include heating, cooling and automotive industry. For the latter Berg develops and manufactures high-precision and safety components for large and specialized suppliers, for example applied within the fields of vibration damping and airbag gas generators.

Since 1992 Berg has also been a shareholder in the Italian firm Mecc-Lan, the market leader in radiator fittings for aluminium radiators in particular.

More about our environmental activities

We see actively practicing environmental protection as a fundamental requirement for successful business operations and securing the future of our manufacturing facility. We have not only set ourselves the target of safeguarding the environmental standard but also of driving it forwards in response to rapidly changing market situations. All employees must follow these principles as a compulsory requirement:

  • Our environmental protection activities are primarily aimed at the avoidance of environmental impacts, and if that is not possible, on reducing them. We base our actions on the state of the art technology in the area concerned and also check whether an even higher technical standard might be possible by taking suitable measures.
  • New areas of business, systems, processes, products and materials are assessed at the outset for their environmental safety, the possibility of reducing environmental effects, the protection of resources and in terms of the safety situation.
  • The awareness of our staff of their responsibilities in respect of quality as well as the environment and health and safety is promoted by means of information and training strategies. Quality management and environmental protection are not least permanent features of our company training and staff development measures.
  • The effects of our business on the environment are regularly documented, assessed and monitored.
  • We maintain open dialogue with the public and the authorities.
