Founding in March 1970 by Wilhelm Modersohn sen. with a total of two employees. It all started with the multiple unit anchors for precast concrete façades which were used in the beginning for private residential buildings for the connection to timber.
As an independent representative of fixing systems from the Lutz company in Wertheim, Wilhelm Modersohn sen. recognized early on that there was a great demand for fixings in the field of masonry façades.
In 1974, an office was rented above a pharmacy in Spenge and the basement served as a small parts warehouse.
As early as 1978 it was decided to build a private residential and office building on Eggeweg 2a. But very quickly even this cellar and garage space was no longer sufficient for the small parts and anchors storage. Production was carried out on the extended work bench of a supplier.
In 1979, the decision was made to extend own production. In order to do this a vacant factory building on the opposite side of the street was rented.
In 1984, a production hall was erected in the nearby industrial area. Production was moved completely to the new hall, thus laying the foundation for their own stainless steel processing. In addition, heavy investments in new production facilities were made. In the beginning, production was almost exclusively for the fixing technology. At this point in time 20 people were already employed.
In the late 90s, production was expanded and an increase in the production of stainless steel series parts for other industries began.
In September 1998, Modersohn joined the Stainless Steel Information Agency (ISER).
In 2000, Wilhelm Modersohn jun. became managing director, following Wilhelm Modersohn sen. as successor. In the same year, the first 4 kW laser cutting system was put into operation. Precision, speed and flexibility of stainless steel sheet metal blanks reached a new dimension!
In 2002, Mr. Modersohn jun. recognised, in cooperation with the company Avesta in Sweden, the application potential of a new steel, or rather a new steel group, the so-called "lean duplex steels". At this time, the first duplex stainless steel was produced under the name Sandvik SAF2304. The Sandvik company had given the license to the adjacent steelworks in Avesta, Sweden.
From 2003 to 2006, numerous attempts at the Federal Institute for Materials Research (BAM, Berlin) and the University of Karlsruhe were made to acquire the building inspectorate approval Z-30.3-19 for the material 1.4362. It was issued in the spring of 2006.
In spring 2008, a move into the new office building on Industriestrasse 23 followed and in Autumn 2009, the 2600 square meter former tennis hall was put into operation as a warehouse.
In spring 2010, the new water jet cutting system (up to 6000 bar cutting pressure) began operation. With this, the cutting of very thick sheet metal up to about 150 mm can be even more precise than with a CO2-laser. Holes which are much smaller than the plate thickness no longer need to be drilled.
The spring of 2012 marked the beginning of further investments in production. The extension of the steel sheet warehouse as well as the cutting plant and the expansion of the existing glass bead blasting plant by two more blast rooms with ultra-modern jet technology, optimised workflow.
In the years 2012 and 2013, the Modersohn company introduced another lean duplex steel to the market by way of the national technical approval Z-30.3-19. These were the materials 1.4062, 1.4162 and 1.4482, which, with S450, have an even higher basic strength and are more interesting for customers financially than the material 1.4362.
At the beginning of 2014, Modersohn put the new fibre laser technology into operation. This makes laser cutting significantly faster, more accurate and cheaper to manufacture.
On 1. May, 2014, Dipl.-Ing. Jürgen Matzelle was appointed Managing Director. As well as his activity as managing director, he is structural and welder engineering specialist. His aim is to strengthen technical fields and product development as well as product standardisation, so that the quality and installation-friendliness of different façade fixing systems are further optimised.
In 2015, the expansion of the administrative building on the Industriestrasse and investments in new brake presses, a laser cutting device and several machines for surface finishing and deburring followed.
The corporate leaders have, to date, put in claims for more than 120 new developments in the field of fixing technology and other industries at the Patent Office in Munich. Patent protection has been granted for numerous applications.
2016 Finishing of the enlarged central and office building at Industriestraße 23 in Spenge. Production halls, dispatch and administration department are now located in one common location.
In 2017, the company acquired the building of the former ALDI market at Industriestraße 30, which now serves as the small parts storage with goods receiving department for parcel services and minor deliveries. The 24-hour storage, pickup for self-collectors, finds its new place here.
Further investments are made in modern machinery and equipment. To the enormous machine park a new water jet cutter and a laser cutting machine with 10 kW capacity were added.
In 2018 the space of the outdoor storage area was increased and is now twice as big as before. This offers more storage space for the bigger parts and sheets of stainless steel. In the future the receiving of goods for bigger parts will be regulated from here.
To optimize the manufacturing process, outdated machines were replaced by new, more efficient and energy-saving machines and facilities. One of the most important new investments of the year is a part levelling machine which straightens and relaxes stainless steel sheets and parts up to a working width of 1600 mm, with a material thickness of 0.6 to 16 mm.
2019 Opening of the new hall for surface treatment. Further investments in machines and facilities are planned.
