The SOUTHWARK METAL SL60-30GA_5IN is a hot-dip galvanized steel round sheet metal pipe designed for low-pressure air distribution in residential and light commercial HVAC duct systems. Manufactured to 30 gauge material thickness, this snap-lock pipe measures 5 inches in diameter and 60 inches in length. The snap-lock end type allows for quick, secure field assembly without additional fasteners in many configurations. Licensed HVAC technicians and sheet metal contractors install this pipe as part of supply or return trunk-and-branch duct layouts.
This round galvanized pipe is suited for residential forced-air heating and cooling systems as well as light commercial ventilation applications. It meets applicable ACCA and SMACNA standards, making it appropriate for duct systems that require compliance with recognized industry guidelines. The 5-inch diameter fits common branch run sizing found in residential construction and retrofit duct work.
Designed as an OEM-style replacement and new-construction component for residential and light commercial round duct systems requiring 5-inch diameter, 30 gauge galvanized pipe with snap-lock ends.
Installation should be performed by a licensed HVAC technician or sheet metal contractor in accordance with SMACNA duct construction standards and local mechanical codes. Secure all joints with drive cleats, sheet metal screws, or approved duct tape rated for HVAC applications as required by the job specification. Support spacing should follow SMACNA guidelines for round duct of this diameter and gauge. Seal all joints with mastic or listed duct sealant where airtightness is required by code or design.
