About us
Schnall GmbH – Anlagenbau is a specialised firm focused on steel construction, pipeline construction and plant engineering, headquartered in Mainz-Kastel with a further location in Langenselbold. The portfolio of work is based on the managing director's 25 years of professional experience and includes the construction of plants, the construction and installation of pipelines in various materials and diameters, the installation of aggregates, machines and vessels, the erection of scaffolding and work platforms as well as building services. The most frequently used welding technique is the TIG process; the speciality is pipeline construction with large diameters, in particular the calculation of pipe runs across floors, room transitions and bends. Reference projects include redundantly designed cooling-water and refrigeration piping (DN 150 to DN 450, partly using the Victaulic pipe system) for data centres as well as heating distribution systems in high-rise buildings. Customers come from the chemical industry, data centres, wastewater treatment plants and waterworks, energy suppliers and combined heat and power plants, as well as from building construction and swimming pool construction.
