Who has ever built a spire? – We did it!

In 2015, the Berlin / Hoppegarten branch was awarded the contract for the steel construction and assembly work for the restoration of the church tower of the Parochialkirche in Berlin’s Mitte district.

After a long preparation phase in which the woodworkers and plumbers also completed their work on the steel substructure, the reconstruction of the church tower of the so-called “Spielkirche” began on 27 June 2016.

The equipment now also includes a carillon of 52 bells, which can be played again in the future. The work was successfully completed on 30 June and the steeple was set at a height of 64 metres.

Hot riveting according to DIN 124


An old process in modern application.


The restoration of historical steel constructions in accordance with the requirements of historical monuments is becoming more and more important. The connection of the individual steel components by the riveting process is an essential aspect of stability and aesthetics. The application is normatively regulated in DIN EN ISO 1090-2 in conjunction with DIN 124, one of the oldest DIN standards still valid today.


We have been using the hot riveting process since 2006. Rivet diameter: 10 - 27mm Component weights: up to 60.0 tons.
