Southwark Metal SL24-30GA_3IN Galvanized Round Pipe 30GA

Product Description

The SOUTHWARK METAL SL24-30GA_3IN is a snap-lock round sheet metal pipe section manufactured from hot dip galvanized steel at 30 gauge material thickness. It measures 3 inches in diameter and 24 inches in length, making it a standard straight section for low-pressure residential and light commercial HVAC ductwork systems. The snap-lock seam construction allows for quick field assembly without additional fasteners along the longitudinal joint. HVAC sheet metal contractors and duct installers use this pipe to build or extend trunk-and-branch or radial duct layouts. Fabricated to meet ACCA and SMACNA standards, this pipe section integrates into code-compliant forced-air supply and return systems.

This pipe section is suited for residential forced-air heating and cooling distribution, as well as light commercial ventilation applications where round galvanized duct is specified. It fits standard 3-inch round duct fittings including elbows, tees, collars, and reducers. Common install scenarios include branch runs off a main trunk, register feeds in tight ceiling or floor joist bays, and short connector sections between duct components. Installers working to SMACNA duct construction standards for low-pressure systems will find this gauge and diameter appropriate for typical residential branch-run service.

Key Features

• Hot dip galvanized steel construction resists corrosion in attic, crawlspace, and mechanical room environments
• Snap-lock seam for fast field assembly without longitudinal fasteners
• 30 gauge material thickness meets SMACNA standards for low-pressure residential branch duct
• 3-inch diameter fits standard round duct fittings and collars
• 24-inch length provides a manageable straight section for branch runs and connector applications
• Fabricated to ACCA and SMACNA applicable standards

Compatibility

Designed as an OEM-style replacement and new-construction component compatible with standard 3-inch round galvanized duct systems built to ACCA and SMACNA specifications for low-pressure forced-air applications.

Installation Notes

Installation should be performed by a licensed sheet metal contractor or qualified HVAC technician in accordance with SMACNA duct construction standards and local mechanical codes. Power down the air handling unit and close the system before cutting into existing ductwork. Secure joints with sheet metal screws and seal all seams with UL 181-listed duct mastic or foil tape per code requirements. Avoid over-crimping the snap-lock seam during handling, as deformation can affect the fit with adjacent fittings.
