Square air ducts are usually made from metal sheets such as galvanized iron or stainless steel.
Galvanized iron: Popular with different thicknesses (eg: 0.48mm, 0.58mm, 0.75mm, 0.95mm, 1.15mm) and different zinc coating levels (Z8, Z10, Z12, Z18...). Suitable for normal environments, without corrosive chemicals.
Stainless steel (usually 201, 304 stainless steel): High durability, good rust and abrasion resistance. Often used in projects requiring high technical requirements or environments that are easily oxidized, such as kitchen exhaust ducts.
Outstanding advantages of square ducts
Space saving: Square or rectangular design helps optimize installation space, especially in corner positions.
Good air flow: Large cross-section helps air circulate effectively, avoiding air loss.
Easy to install and transport: Light weight, easy to connect pipe sections with C-brackets, TDC flanges, flange clamps, bolts.
Reasonable price: Usually has a more competitive price than some other types of ducts.
Flexible in design: Can customize the size to suit the requirements of each project.
Application
Air conditioning and ventilation systems: Air transmission and distribution in buildings, offices, apartments, hotels, shopping centers.
Smoke extraction systems: Used in restaurants, industrial kitchens.
Industrial odor treatment: Extracting toxic air, providing clean air in production workshops and factories.
Dust extraction systems: In factories and industrial parks.
