Tubes
Since 1979, Zwahlen & Mayr has been a leading producer of welded stainless steel under the brand ZM TUBES.
Nowadays, ZM manufactures three types of stainless-steel tubes:
for high precision applications.
Welded tubes
Strong corrosion resistance, precise forming, and excellent roughness of surface even along the welding area are the keys to success that make ZM TUBES a world-class supplier for heat exchangers, evaporators, condensers and feedwater heaters.

Seamless tubes
We are developing an entire division dedicated to the seamless tubes: a new plant to produce seamless stainless-steel tubes was installed at ZM in 2021, to meet the needs of all industries where welded pipes represent a risk to be avoided.

Steel constructions
The construction of buildings and other works, such as stadiums and bridges, requires a specific combination of skills, which goes beyond those required by production.
Zwahlen & Mayr has invested in building a team of experienced professionals and in the infrastructure and technologies to support them and ensure the effective management of complex construction projects.
