Overview

Maincor Rohrsysteme GmbH & Co. KG (stylised MAINCOR) is a German manufacturer of plastic pipe systems headquartered in Schweinfurt, Franconia, with production at its sites in Schweinfurt and Knetzgau. The company describes itself as a mid-sized family business with a strong emphasis on quality and innovation, and it markets its output under the slogan "Made in Germany". Its workforce is given as around 400 to 430 employees across its operations. The business is organised into two main divisions. Rohrsysteme Gebäudetechnik (building services pipe systems) covers products for sanitary and heating installation as well as controlled residential ventilation, sold largely through direct sales to installers. Rohrsysteme Industrie (industrial pipe systems) serves OEM customers in automotive, general industry, electrical installation, household appliances, cable protection and protective conduit applications. The product range extends from pipes for the automotive, industrial and white-goods sectors through heating and sanitary piping to capillary tubes used in medical technology, and the company also offers plastic surface finishing such as fluorination. Maincor was originally founded in 2004 as PP Maincor GmbH & Co. KG and PS Maintools GmbH & Co. KG. It expanded through acquisitions and the creation of sales companies in Germany and Europe, was converted into a Maincor AG in 2008, and introduced employee participation in 2011. In August 2013 the Maincor AG group filed for insolvency under self-administration; following restructuring and the sale of various business units the proceedings ended in December 2013, and the present company Maincor Rohrsysteme GmbH & Co. KG emerged. Employment fell from 630 to 535 during the restructuring and stood at around 220 at the turn of 2014/2015. Today Maincor positions itself as a customer-focused supplier whose "core product is customer satisfaction", combining modern technology with fast, direct service to heating and sanitary customers on site. Products can be ordered through an online shop, by telephone, by e-mail or via the responsible field sales representative, with delivery from a central warehouse and most products shipped within one working day. The company has received a number of regional and national awards, including the Top 100 innovation award, the Bavarian Founder's Prize, Bayerns BEST 50 and the Bavarian State Medal for special services.

History

Maincor was originally founded in 2004 under the names PP Maincor GmbH & Co. KG and PS Maintools GmbH & Co. KG. In 2006 the company acquired Maincor Anger in Marl and founded various sales companies in Germany and Europe. In 2008 it was converted into a Maincor AG, and in the same year sales companies were established in Poland and Austria. In 2009 the DRS Rohrwerke Sachsen was founded. In 2011 the company Weißenberger in Mellrichstadt was acquired, and Maincor Slowenien and Sytec in Italy were founded with Maincor participation; employee participation at Maincor was also introduced in 2011. In August 2013 the Maincor AG group had to file for insolvency (case number IN 280/13), which was carried out under self-administration. Through restructuring and the associated sale of various business units, the insolvency was concluded in December 2013, giving rise to the company Maincor Rohrsysteme GmbH & Co. KG. The group's workforce fell from 630 to 535 during this process. At the turn of 2014/2015, 220 employees were still working for the company. Today the company is headquartered in Schweinfurt and produces at its two sites in Schweinfurt and Knetzgau with around 400 employees, making plastic pipes for a wide range of applications. It describes itself as a mid-sized family business rooted in Franconia, with employees at the heart of the company, and it operates two business divisions: Rohrsysteme Hochbau (building construction pipe systems) and Rohrsysteme Industrie (industrial pipe systems). Its product range spans the automotive, industrial and white-goods sectors, cable protection, heating and drinking water, and capillary tubes for medical technology. The company has received numerous awards, including the Top 100 innovation award in 2006, Entrepreneur of the Year in 2007 and 2009, the Axia Award in 2008, the Bavarian Founder's Prize and Bayerns BEST 50 in 2009, the Bavarian State Medal for special services in 2011, and Bayerns BEST 50 again in 2019.
