Southwark Metal SL60-30GA_3IN Round Sheet Metal Pipe 30GA 3in

Product Description

The SOUTHWARK METAL SL60-30GA_3IN is a 30-gauge hot-dip galvanized steel round pipe section used in residential and light commercial HVAC duct systems. Measuring 3 inches in diameter and 60 inches in length, it is designed for supply and return air distribution in forced-air heating and cooling applications. The snap-lock seam provides a secure, tool-minimal assembly that speeds up installation on the job. Licensed HVAC sheet metal mechanics and ductwork installers are the primary trade for this product.

This pipe section is suited for low-pressure round duct systems built to ACCA and SMACNA standards. It fits into residential furnace and air handler supply trunk systems, branch runs, and exhaust or ventilation duct assemblies where round galvanized pipe is specified. The 3-inch diameter is a common size for branch feeds in zone systems and bath or kitchen exhaust tie-ins. The full 60-inch length reduces the number of joints needed per run, which limits potential air leakage points.

Key Features

• Hot-dip galvanized steel construction resists corrosion in both conditioned and unconditioned spaces
• 30-gauge material thickness meets light-duty HVAC duct fabrication standards
• Snap-lock seam allows field assembly without additional fasteners at the longitudinal seam
• 60-inch length reduces joint count per duct run
• Compliant with ACCA and SMACNA applicable standards for sheet metal ductwork
• 3-inch round diameter fits standard fittings, collars, and take-offs designed for that size

Compatibility

Designed as an OEM-style replacement and new-construction round duct component compatible with standard 3-inch round duct fittings, starting collars, elbows, and end caps built to ACCA and SMACNA specifications.

Installation Notes

Installation should be performed by a licensed HVAC technician or sheet metal mechanic in accordance with SMACNA duct construction standards and local mechanical codes. Shut off the air handling system before connecting or modifying ductwork sections. Seal all longitudinal and circumferential joints with UL 181-listed mastic or foil tape as required by the applicable energy code. Secure the pipe to structure at intervals specified by SMACNA hangar and support guidelines to prevent sag or separation.
