Southwark Metal SL60-30GA_7IN Round Sheet Metal Pipe 30GA 7in

Product Description

The SOUTHWARK METAL SL60-30GA_7IN is a 7-inch diameter, 60-inch length round sheet metal duct pipe fabricated from hot-dip galvanized steel at 30 gauge. It uses a snap-lock seam construction that speeds assembly on the job site without separate fasteners for the longitudinal joint. This pipe is a core component in low-pressure forced-air distribution systems and is sized, fabricated, and tested to meet ACCA and SMACNA standards. Sheet metal workers and HVAC installers use this pipe for trunk-and-branch and radial duct layouts in both new construction and retrofit work.

This pipe is suited for residential and light commercial forced-air heating and cooling duct systems where round galvanized pipe is the preferred distribution method. The 7-inch diameter makes it a common branch or secondary trunk size feeding diffusers, registers, or zone dampers. At 60 inches per section, it reduces the number of couplings needed on longer runs, lowering both material cost and potential leak points. It performs well in attic, crawlspace, basement, and mechanical room installations.

Key Features

• Hot-dip galvanized steel construction resists corrosion in damp or unconditioned spaces
• Snap-lock seam for fast, tool-minimal longitudinal joint closure on the job site
• 30 gauge material thickness meets light-duty low-pressure duct applications per SMACNA guidelines
• 60-inch section length reduces coupling count on straight runs
• ACCA and SMACNA applicable standard compliance supports code-required duct design documentation
• 7-inch round diameter is a standard branch and secondary trunk size in residential forced-air systems

Compatibility

Designed as an OEM-style component for residential and light commercial round galvanized duct systems built to ACCA and SMACNA standards. Mates with standard 7-inch round duct fittings, collars, dampers, and couplings.

Installation Notes

Installation should be performed by a qualified sheet metal worker or licensed HVAC contractor in accordance with SMACNA duct construction standards and local mechanical codes. Snap-lock the longitudinal seam fully before installing the section into the duct run, and secure joints to adjacent fittings with sheet metal screws and UL-listed duct tape or mastic sealant as required by local code. Support spacing should follow SMACNA hanger and support guidelines for round duct of this diameter and gauge. Power down the air-handling unit and verify zero airflow before cutting into or modifying an existing duct system.
