Southwark Metal SP10-26GA_5IN Spiral Sheet Metal Pipe 5in 26GA

Product Description

The SOUTHWARK METAL SP10-26GA_5IN is a spiral round sheet metal pipe fabricated from hot dipped galvanized steel at 26 gauge material thickness. Measuring 5 inches in diameter and 10 feet in length, this pipe is used to construct low-pressure supply and return air duct systems in residential and commercial HVAC installations. The galvanized coating resists corrosion in both conditioned and unconditioned spaces. Spiral seam construction delivers a rigid, consistently round cross-section that maintains airflow efficiency across the length of each section. HVAC sheet metal contractors and mechanical installers work with this pipe as a standard component of ducted forced-air systems.

This pipe is suited for round spiral duct systems in forced-air heating and cooling applications. It connects to standard 5-inch spiral fittings, take-offs, elbows, and end caps used in residential and light commercial ductwork. Fabrication and installation comply with ACCA and SMACNA standards for sheet metal duct construction, making it appropriate for permitted mechanical work where code-compliant duct systems are required. It is commonly installed in attics, basements, crawlspaces, and mechanical rooms as part of a distributed air delivery system.

Key Features

• Hot dipped galvanized steel construction for corrosion resistance in HVAC duct environments
• 26 gauge material thickness meets SMACNA standards for low-pressure duct systems
• Spiral seam fabrication provides structural rigidity and a true round profile
• 5 inch diameter fits standard round spiral duct fittings and boots
• 10 foot length reduces the number of joints required in straight duct runs
• Meets ACCA and SMACNA applicable standards for mechanical duct installation

Compatibility

Designed for use with standard 5-inch round spiral duct fittings, connectors, and accessories in low-pressure forced-air HVAC duct systems built to ACCA and SMACNA guidelines.

Installation Notes

Sheet metal duct installation is performed by licensed HVAC contractors or journeyman sheet metal mechanics. All ductwork should be sealed at joints with mastic sealant or UL 181-listed foil tape per SMACNA and local mechanical code requirements. Secure each pipe section with sheet metal screws before applying sealant and support runs at intervals required by the applicable mechanical code. Shut down and lock out the air handling system before modifying or extending any connected ductwork.
