In Stock and made ready for installation.

Acosta Sheet Metal Mfg.'s Spiral Aluminum Lined, or commonly referred to as "Alumaspiral" is the first and only of its kind.

Alumaspiral is stocked in a variety of diameter sizes, and is fabricated with features that help speed up installation on the job site, and ultimately save money on the job. 

Made with corrosive-resistant aluminum (3003 H14 Aluminum), Alumaspiral is significantly lighter than galvanized pipe, without sacrificing the durability of spiral fabrication. 

Key features: 

  • Collars are "built in", and part of the pipe–it's all one piece. 

  • Wrapped in 4.2 R-value, Johns Manville GreenGaurd Certified Insulation. 

  • Averages 30% lighter than galvanized spiral pipe across all sizes. 

  • 7.5-foot length allows for easier installation, when compared to longer lengths.

  • Fabricated according to SMACNA guidelines Table 3.14.
