Rectangular air ducts made of galvanized steel

Rectangular air ducts and fittings for them are made of galvanized steel up to 2500 mm long and b-0.5 mm thick b-0.7 mm b-1.0 mm thick. Any type of size.

Most often, in the design of ventilation systems, rectangular shapes of air ducts are used. One very important advantage is that they can be customized to the necessary conditions of the structure. That is, taking into account the architectural delights of the room, you can reduce the height of the duct, but increase the width, thereby leaving the cross-sectional area unchanged. The latter plays the most important role in design and calculations. It is the cross-sectional area that ensures the unimpeded movement of the required amount of air through the ventilation system.

Also, air ducts with a length of 1250 mm have a great advantage in price due to their manufacture on an automatic line.

Duct connection type:

  • Flanged
  • Rack

Air ducts made of galvanized steel are allowed to be used almost everywhere: in any climatic conditions and for any type of ventilation. The only limitation is that they cannot be used to transport aggressive gas-air mixtures. The protective layer of zinc on the inner and outer surface of the air duct protects it from corrosion, and even on damaged areas, a protective film is formed when interacting with oxygen.
