Southwark Metal SL24-26GA_20IN Round Sheet Metal Pipe 26GA 20in

Product Description

The SOUTHWARK METAL SL24-26GA_20IN is a 26-gauge hot dip galvanized steel round pipe section used in low-pressure HVAC ductwork systems. It measures 20 inches in diameter and 24 inches in length, with a snap-lock seam construction for fast, tool-minimal assembly in the field. The hot dip galvanized finish provides corrosion resistance suited to both conditioned and unconditioned spaces. This pipe section is installed by sheet metal workers and HVAC technicians as part of supply or return trunk and branch duct systems in residential and light commercial applications.

This round pipe section is used in forced-air HVAC duct systems where large-diameter round trunk lines are required. It is appropriate for new construction and retrofit installations in residential and light commercial settings. The 20-inch diameter makes it suitable for high-volume supply or return trunk runs. Fabricated to ACCA and SMACNA standards, it fits into duct systems designed and installed to those widely referenced industry specifications.

Key Features

• 26-gauge hot dip galvanized steel construction for durability and corrosion resistance
• 20-inch diameter accommodates high-volume airflow trunk duct applications
• 24-inch length simplifies layout and reduces the number of joints needed
• Snap-lock seam design allows fast field assembly without additional seaming tools
• Meets ACCA and SMACNA applicable standards for sheet metal ductwork

Compatibility

Designed as an OEM-style replacement and new-construction component for ACCA- and SMACNA-compliant round duct systems requiring 20-inch diameter, 26-gauge galvanized pipe sections with snap-lock seam construction.

Installation Notes

Installation should be performed by a licensed sheet metal mechanic or HVAC technician following SMACNA duct construction standards and local mechanical code requirements. Power down the air handling unit before connecting new duct sections, and seal all joints with listed duct sealant or approved foil tape per code. Ensure hangers and supports are spaced in accordance with SMACNA guidelines for the pipe diameter and gauge. Do not substitute this pipe in systems requiring higher-gauge material where structural or pressure class requirements demand it.
