24" x 8" x 5' Trunk Duct

24" x 8" Galvanized Trunk Duct – Rectangular Supply and Return Air Distribution

The 24" x 8" trunk duct is a rectangular galvanized steel section fabricated for use in HVAC air distribution systems. Constructed from 26-gauge galvanized sheet steel with a G-30 coating, this duct provides strength, corrosion resistance, and long-term durability. Its loose cleat connection design allows for precise installation and alignment in both commercial and residential duct systems.

Application

This trunk duct is designed for main supply or return air runs, delivering uniform airflow in heating and cooling systems. Its rectangular cross-section supports consistent static pressure management, making it suitable for large distribution systems where airflow efficiency and compliance with project specifications are critical.

Performance Characteristics

• Material: 26 ga galvanized sheet steel with G-30 protective coating
• Dimensions: 24 inches (width) x 8 inches (height)
• Length: 60 inches
• Connection Type: Loose cleat design for secure mechanical fastening
• Use: Supply and return air ductwork in commercial and residential HVAC systems

Installation Guidelines

Sections should be installed using standard SMACNA practices. Loose cleat joints require appropriate fasteners and sealants to ensure airtight connections and compliance with local building codes. Adequate supports must be provided at code-specified intervals to prevent deflection and maintain system integrity.

Advantages

• Code-Compliant Fabrication: Manufactured to meet SMACNA and ASTM-A653 standards for galvanized duct construction.
• Durable Construction: G-30 galvanized coating enhances resistance to corrosion and handling wear.
• Efficient Airflow: Rectangular profile supports balanced distribution with minimal pressure loss.
• Professional Grade: Designed for long-term use in engineered HVAC installations.

The 24" x 8" trunk duct provides contractors with a dependable, code-compliant solution for primary duct runs. Its robust construction, accurate sizing, and reliable connection system make it well-suited for both new installations and retrofit applications requiring durable and efficient air distribution.
