Production and Machinery

Duct quality is decided in production: how accurately the sheet is cut, how tight the seam is and how well the parts fit together. That is why our factory runs modern ventilation machinery from the Turkish manufacturer SENTE.

How a duct is made

  1. Reviewing the project or specification and confirming dimensions
  2. Cutting the sheet to exact size on the machine
  3. Forming and bending seams and edges
  4. Assembly and quality check
  5. Packing and delivery to site
