Single layer louver vent can ensure air circulation efficiency and meet the ventilation needs of buildings through reasonable louver design, high-quality material selection, good sealing performance

The PVC composite aluminum foil tube uses PVC material with excellent corrosion resistance as the outer layer, which makes it perform well in various corrosive environments.

These advantages enable PVC composite aluminum foil tube to perform well in various ventilation systems, providing strong support for users' production and life.

Hot-dip galvanized spiral duct is a ventilation duct designed for harsh environments, especially in highly corrosive environments.

Good fire resistance is also one of the reasons why galvanized air ducts are widely used in engineering.

In actual construction, full welding can be done, and it should not be a right-angle flange to ensure that it is not affected by the thermal expansion and contraction of the duct, while also strengthening the duct.
