Company history

Our company development from 1986 to this day


Oltmanns GmbH was founded in Emden in 1986 with 15 employees.

From there we served local customers in the areas of steel and engineering. Since the beginning the automotive industry counted as the most formative customer and still serves as the motivator for the continuous development of our high quality standards.

Our continuous growing activity and increasing range of customers is based on our quality standards, so we eventually reached production limit at the location in Emden.

Schlosserarbeiten & Services


In spring  2001 we moved to our new production hall in the community of Ihlow, located in the industrial park Riepe – Leegmoor, Amboßstr. 2.

This location was targeted due to its proximity to the motorway A31. Complex processes cause ever-increasing logistical challenges for road transports or international shipments. The new location combines all necessary logistical and economic advantages to effectively serve our customers.

to this day

Our production hall has grown to currently 1400m² with 35 highly qualified employees.

Today our customers include businesses in the industry, trading, construction, hydraulic engineering, petro chemistry and wind- and offshore industry, but  our price-performance-ratio applies to the farming and private customers as well.

Quality assurance is our trademark, with customer satisfaction being our primary goal and motivation.
