Product Description

Jinan United Perfect Building Materials Corporation
is professional manufacturer of Flexible ducts and we have engaged in research, develop and produce flexible duct products for 10 years with rich experience.
We provide customers with green and eco-friendly bare flexible duct, insulated flexible duct, PVC flexible duct, semi rigid duct products etc. to create a better working and living environment for people.
1, Aluminum Bare Flexible Duct


    
Aluminum bare flexible duct (Aluminum non-insulated flexible duct) is specifically produced for low and medium pressure heating, cooling, ventilation, exhaust and air conditioning systems. Aluminum non-insulated flexible duct (ABD series) is produced from multi layer aluminum strengthened with high tension hard steel spring wire. It has high elasticity and flexibility.

2, Aluminum Insulated Flexible Duct     

Aluminum Insulated Flexible Duct is made of aluminum/polyester lining with well balanced steel spiral internal duct+(16-32)kg/m3-25mm glass wool+ aluminum/polyester external duct.
It is suitable for the densely-populated area with high requirement of the environment area, such as school, hospital, laboratory, supermarket, office, stadium, theater etc.
