Southwark Metal TD_30X10X60 Sheet Metal Trunk Duct

Product Description

The SOUTHWARK METAL TD_30X10X60 is a hot-dip galvanized steel sheet metal trunk duct section designed for forced-air HVAC distribution systems. Measuring 30 inches by 10 inches in cross-section and 60 inches in length, this trunk duct delivers a rigid, corrosion-resistant air pathway from the air handler or furnace to branch takeoffs throughout the structure. It ships with button snaplock seams, S-cleat end connections, and drive connection hardware included. The duct body is cross-broken for additional panel stiffness, reducing flex noise and maintaining dimensional stability under static pressure. Licensed HVAC sheet metal mechanics and ductwork installers are the primary trade for this product.

This trunk duct section is suited for residential and light commercial forced-air systems where main trunk runs are fabricated or extended from a central air handler, furnace, or rooftop unit. The 30-by-10-inch profile accommodates high-volume supply or return trunk applications. It is fabricated to ACCA and SMACNA standards, making it compatible with duct systems designed under Manual D airflow calculations and SMACNA duct construction guidelines. Typical installation scenarios include new construction trunk-and-branch layouts and retrofit trunk extensions where additional duct footage is needed.

Key Features

• Hot-dip galvanized steel construction resists corrosion in both conditioned and unconditioned spaces
• 60-inch section length reduces the number of joints required in long trunk runs
• Button snaplock seam with S-cleat and drive connection hardware included for field assembly
• Cross-broken duct panels add stiffness and reduce drumming under airflow pressure
• Fabricated to ACCA and SMACNA applicable standards

Compatibility

Designed as an OEM-style sheet metal trunk duct section for residential and light commercial forced-air HVAC systems built to ACCA and SMACNA ductwork standards. Compatible with standard S-cleat and drive connection fittings used in rectangular trunk-and-branch duct systems.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal mechanic familiar with SMACNA duct construction standards. Power down the air handler or furnace and verify the system is de-energized before connecting new duct sections. Joints should be secured with the included S-cleat and drive connections and sealed with UL 181-rated mastic or foil tape per local mechanical code requirements. Support hangers should be spaced per SMACNA guidelines to prevent sag and maintain alignment across the trunk run.
