Welcome to our shared website

Are you looking for flexible system solutions from a single source?

Do you supply volatile markets and need high availability despite low inventories?

Need-based material supply at fair prices is your priority?

Due to our high level of vertical integration, sustainable material coverage and careful material planning, we can support you.

We are happy to talk to you about a tailor-made delivery program.

In addition to our own warehouses, we provide consignment goods to many customers. This allows a smooth and inexpensive material flow. We fill the warehouse with the agreed minimum and maximum quantities invoicing the customer only when dispatching the goods from the warehouse. This enables us and the customer to remain flexible.

1994	Company founded as a trading company in Siegen. The innovative piping systems for solar thermal systems opened up the heating market with installation-friendly stainless steel corrugated pipe systems.
1999	We presented our first ready-to-install pre-insulated pipe system at the ISH trade fair in Frankfurt. This enabled sales to manufacturers of heating equipment and solar thermal technology. Many brand manufacturers are taking our products into their range of accessories.
2000	Split of ownership and operating company and change of name. Investment in buildings and facilities has enabled us to grow with the requirements of our customers and the creation of additional production capacities
2004	We invested in our own metal hose machines. From high-quality precision strip, we manufacture longitudinally welded tubes, which are formed into corrugated tubes in a continuous process. A total of 11 production lines allow us flexible production across all nominal diameters and types. With three fully automatic braiding machines, we produce high quality stainless steel wire braids.
2006	We exhibited for the first time at the trade fair TUBE in Düsseldorf.
2010	We coated flexible insulation materials with weather-resistant PE film with our co-extrusion line. On our flame brazing machine we braze products made of stainless steel tubing with ends made of copper materials.
