Your partner for complete solutions in the energy and industrial sectors

The constant demand for comprehensive solutions in plant and pipeline construction has prompted us to further expand our range of services. Company founder Walter Zusteg has acquired the majority shares of Innomontage AG, a company with more than 16 employees specializing in stainless steel and steel pipeline construction as well as district heating systems.


All welders have recognized qualifications, including module A2 according to Directive 2014/68/EU (Pressure Equipment Directive).

With this step, we are strengthening our position as a comprehensive solutions provider and offering you even more expertise, quality and reliability.


ZAG Engineering takes over project management and coordinates all trades.
