internal wall is smooth the resistance is small gas tightness is good the bearing strength is high

Product characteristic: Galvanizes steel sheet metal duct is the most traditional and widespread product in air conditioning project, in the system of ventilation and discharges fume at present.

 

Galvanizes steel sheet metal duct wall is smooth, the resistance is small, gas tightness is good, the bearing strength is high. It can be conveniently make on the spot, and close with the civil engineering coordination, also can suit the very complex ventilated project.

 

Its construction cost is lower than the stainless steel plate duct, the use is very widespread.

 

Applicable scope: is widely to apply ventilation, and air-conditioning system.

 

Sphere of production: It divides the circle and the rectangular two kinds.We also can product different kinds shape, and specifically model duct according to the user’ need.
