Southwark Metal SL60-30GA_4IN Galvanized Round Pipe 30GA 4in

Product Description

The SOUTHWARK METAL SL60-30GA_4IN is a snap-lock round sheet metal pipe section fabricated from hot dip galvanized steel at 30 gauge thickness. It measures 4 inches in diameter and 60 inches in length, making it a standard full-length section for low-pressure air distribution ductwork. The snap-lock seam construction allows for fast field assembly without additional fasteners. HVAC sheet metal installers and duct fabricators use this pipe in residential and light commercial forced-air systems where a durable, corrosion-resistant round duct section is required.

This pipe section is suited for round duct trunk and branch runs in forced-air heating and cooling systems. At 4 inches in diameter, it is commonly used for individual room supply or return branches off a larger trunk line. The hot dip galvanized finish provides resistance to moisture and rust, appropriate for installations in unconditioned spaces such as attics, crawlspaces, and mechanical rooms. Fabrication and installation conform to ACCA and SMACNA standards for sheet metal ductwork.

Key Features

• Hot dip galvanized steel construction resists corrosion in unconditioned and semi-conditioned spaces
• Snap-lock seam for fast, tool-minimal field assembly
• 30 gauge material thickness meets standard residential duct gauge requirements
• 4 inch diameter fits standard branch fittings, collars, and takeoffs
• 60 inch length provides a full 5-foot section per piece, reducing field joints
• Manufactured to ACCA and SMACNA applicable standards

Compatibility

Designed as an OEM-style replacement and standard-stock round pipe section compatible with 4 inch snap-lock round duct fittings, collars, starting collars, and elbows in residential and light commercial forced-air duct systems built to ACCA and SMACNA guidelines.

Installation Notes

Sheet metal duct installers should follow SMACNA duct construction standards and local mechanical code requirements when sizing, supporting, and sealing this pipe section. All joints and seams must be sealed with listed duct sealant or approved metal tape per applicable energy codes before system commissioning. Support spacing should comply with SMACNA hanger and support guidelines for round duct. Ensure the system is de-energized and the air handler is shut down before modifying or extending any duct section.
