Spiral Seam Duct

AIL Spiral Seam Duct is suitable for all types of commercial air duct systems.

AIL produces a full line of lock-type Spiral Seam Duct to meet the most demanding needs of air conditioning, fume exhaust, ventilation, and other air duct applications. Spiral Seam Duct combines the proven strength of corrugated metal pipe with the flow capacity of a smooth inner wall. Look into the many benefits of using Spiral Seam Duct from AIL for your next commercial air duct system:

Cost Efficiency
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 in air duct systems.

Adaptability
AIL’s Spiral Seam Duct 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 brochure for size details. Where architectural specifications demand, AIL can produce Spiral Seam Duct with a G60 galvanized satin coat finish, which is ideally suited for painting air ducts after installation.

Durability
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 commercial air duct systems are in severe environmental conditions due to excessive humidity or corrosive fumes, Spiral Seam Duct can also be made of aluminum, stainless steel or PVC-coated steel.

Superior Performance
Spiral Seam Duct provides superior performance in air ducts 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, in commercial air duct systems.

Quality Standards
To ensure delivery of a consistently high quality product, AIL manufactures Spiral Seam Duct according to SMACNA and ASHRAE specifications for commercial air duct systems.

Quick Delivery
To accommodate production on demand, AIL maintains an inventory of galvanized G90 steel in various thicknesses. Protective temporary shipping caps are available on request.
