Consider the many advantages of AIL’s Spiral Seam Duct
For low, medium, or high velocity cooling and ventilating systems, AIL’s Spiral Seam Duct offers a triple combination of price, performance, and ease of installation that ensures superior results and bottom-line savings.
Where architectural specifications demand, AIL can produce Spiral Seam Duct with a G60 galvanized satin coat finish, which is ideally suited for painting after installation.
AIL’s Spiral Seam Duct is typically made of steel with a galvanized or satin coat finish, both of which will provide a long, trouble-free service life. However, where environmental conditions are severe due to humidity, corrosive fumes, etc., Spiral Seam Duct can also be made of aluminum, stainless steel or PVC-coated steel.
Spiral Seam Duct provides superior performance while minimizing energy costs. Strong, leak-proof seams, a round profile, and a smooth interior help make it the product of choice for moving large volumes of air rapidly and without turbulence.
To ensure delivery of a consistently high quality product, AIL manufactures Spiral Seam Duct according to SMACNA and ASHRAE specifications. It is available in diameters from 100 mm (4") to 1.5240 m (60"). It is normally produced in standard 3 m (10') sections, but shorter or longer lengths can also be supplied. See table below for details.
To accommodate production on demand, AIL maintains an inventory of commercially-galvanized G90 steel in various thicknesses at its centrally-located facility in Dorchester, New Brunswick. Protective temporary shipping caps are available on request.
Although the primary function of AIL’s Spiral Seam Duct is for air systems, with the added strength and rigidity of the corrugations it can also be used as a concrete void form.
