Tubes

Since 1979, Zwahlen & Mayr has been a leading producer of welded stainless steel under the brand ZM TUBES.

Nowadays, ZM manufactures four types of stainless-steel tubes:

  1. welded;
  2. seamless;
  3. redrawn for high precision;
  4. high pressure tubes.

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.

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.
