75 years of KÖPP

75 years

KÖPP celebrates the company’s 75th anniversary - 1938-2013.


In 2014, Oliver Köpp, the last member of the founding family left the company. The company is now completely owned by the Raab family. Sole Managing Director is Dipl.-Kfm. Achim Raab.



Mid 2015 KÖPP takes over two SAPSOL presses from the British manufacturer Flexi-Cell (UK) as well as further equipment for the production of cellular rubber and installs it at its Romanian facility. Thereby, production capacity in Romania increases to 150.000 blocks per annum.

Under its new, streamlined management, W. KÖPP GmbH & Co. KG has achieved the best results in the company’s history.


The aim behind all our investments and efforts is for W. KÖPP GmbH & Co. KG to continue to grow. The way we achieve this remains the same: Developing our proven offering further and daring to try new thing while always keeping customer’s need in mind.


Since the foundation of SC Koepp Romania SRL in 2011, the floor space and production area of the plant in Arinis, Romania has increased more than tenfold.

Further investments in production space and machinery , especially in additional splitting capacity, will follow in 2021. Köpp's position as the largest manufacturer of rolled goods in Europe will thus be consolidated and expanded.

In order to be able to meet the increased demand for block products, additional production lines for the manufacture of foamed cellular rubber and polyethylene blocks will be commissioned at the Romanian site.
