And its components can be exposed under all conditions of temperature and corrosion. For cases of more severe repairs and thicker materials, the  MAESTRO SYSTEM.
  • Another advantage of this type of repair is that it is done in the same place and with a minimum disassembly of the machine to be repaired.
