Brief introduction
Steel materials of ventilation ducts now is the most widely used in conditioning project, ventilating air and discharge fume systems.It suitble to civil fense project,hotels,marketings,and industrial buildings for air vcntilations and discharging fume.
The internal of steel piplines is very smooth,and withgood features of low resistance,high compression strength.
Our producst can be devided into galvanized steel pipelines,stainless steel duct and normally steel pipeline.For the galvanized ones,it can be used in all air conditioning and ventilation systems,and stainless ones can be used into the ventilation systems with corrosive gas,and important ventiltions.And normally ones,can be used into toxic filtration in civil fense systems.The thickness of ducts can be designed by technical departments,and the flange specification are same as the galvanized ones'
