1600D Spiral Duct

Categories Round Duct, Spiral Duct

Diameter: 1600 mm

Thickness: 1.2 mm

Material: Galvanised steel coil

Our Spiral Duct is manufactured with CE certified machinery according to AS4254 requirements ensuring minimal duct leakage and energy efficient fan operation. Hard Spiral Ducts are manufactured using 0.6mm, 0.8mm, 1.0mm and 1.2mm galvanised grade G250 sheet metal with Z275 coating class.

There are reinforcing ribs on the spiral duct so there is not need to use thick metal coils while still ensuring the stiffness and load-bearing capacity of the round duct.
