The origin of PASSCO is in Siegerland where ores have been mined for centuries
and iron production shaped both the land and its people. A high performance iron
and metal processing industry developed in this area.
PASSCO was established in 1852
Originally. sheet metal from rolling mills in Siegerländer were used to make ash
containers. oven pipes and steel tanks.
The founder of the company. Hermann Müller. was one of the first to introduce
autogenous cutting and welding methods in the region. In 1893 he retired from his
active duties in the company.
His son-in-law. Heinrich Pass. joined the company and marketed the product range
even outside of the region. For example. he went to East Prussia and introduced the
galvanised water bucket where up to then only wooden pails were used.
The operations were expanded every year and in 1906. a galvanising process was
added to the sheet metal plant
Heinrich Pass retired in 1935 and transferred the management of the company to his
son-in-law Carl Hiekmann.
In 1937. production was relocated to Siegen-Weidenau into the Industriestraße.
The number of workers and employees grew from 50 in 1910 to nearly 300 in 1960.
