A total of plate flange duct, also known as no flange duct, its production form than the traditional rectangular duct processing speed faster, more convenient, smaller air leakage rate. The advantage is to save materials, reduce investment in engineering; air leakage is small, reduce energy consumption, save operating costs, popular construction enterprises welcome. The United States and Europe and other developed countries from the nineties began to use the ductless flange connection.
Galvanized steel sheet metal duct is the current air conditioning project, ventilation and exhaust system used in the most traditional, the most extensive products.
Galvanized steel sheet metal pipe wall smooth, small resistance, good air tightness, high pressure strength. Steel ducts made on-site system to facilitate, and civil engineering works closely with, can be suitable for very complex ventilation works.
Its cost is lower than the stainless steel plate duct, the use is very wide.
Scope of application:
Galvanized steel sheet duct is widely used in a variety of ventilation, air conditioning systems.
Ducts round and rectangular two, according to the different needs of users of the production of various types, a variety of models of ducts.
