About us


The company Sperling, founded in Braunschweig in 1921, has been taken over by Mr Eckart Kathmann in June, 1963.

The company’s main field of activity, until then lying in private house building, was shifted towards industrial plant construction in the period following. This was necessary to establish a basis for the continuous extension of the works in the years to follow.

So, new company premises have been built on Pippelweg 39 in 1967, to which the company moved in March, 1968. Through additional new buildings for the distribution construction and the sheet metal locksmith’s workshop as well as a new office building, the company continuously expanded till the end of the eighties.

After 1989, the company expanded by taking over other companies. The certification according to DIN EN ISO 9001 in 1997 also proves the continuous further development.
