National Mfg N215-772 Galvanized Sheet Metal 24x24 26 Gauge

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N215-772 is a 24 x 24 inch galvanized steel sheet intended for HVAC ductwork fabrication, flashing, and general sheet metal work. Manufactured to 26 gauge thickness, it carries a continuous hot-dip zinc coating that resists flaking and peeling during forming operations. The steel is produced with lock-forming qualities, meaning it bends and shapes cleanly without cracking or surface failure. This sheet meets ASTM Specification A653, the standard for hot-dip galvanized steel sheet. HVAC technicians, sheet metal fabricators, and plumbers use this material for custom duct patches, transitions, flashing details, and repair work in both residential and light commercial applications.

This sheet is sized at 24 x 24 inches, making it practical for small-to-medium duct patch work, custom pan fabrication, and field-cut flashing. At 26 gauge, it offers the combination of rigidity and workability required for hand-tool bending and brake-formed shapes without specialized heavy equipment. It is sold in packages of 3 sheets per unit of measure. Typical users include HVAC contractors, plumbers, and general trades performing sheet metal repairs or custom fabrication on residential and commercial jobs.

Installation Notes

Sheet metal work should be performed by a qualified HVAC technician or sheet metal fabricator using appropriate hand seamers, tin snips, or a brake press. Cut edges are sharp — use gloves and eye protection during handling and forming. For duct applications, follow SMACNA guidelines for gauge selection and joint sealing. Shut off all air-handling equipment before performing duct repairs or modifications.
