21.5" x 17.5 with the flares.
A section of HVAC sheet metal ductwork, likely a main trunk line duct. Material and Gauge: The item is constructed from galvanized sheet metal. Fabrication Details: The duct features a "cross break" on the flat surface to provide rigidity and reduce vibrations. Usage: Such items are used to distribute air from heating or cooling units throughout a building.

• The "CSI" Stamp: This stands for California Steel Industries.
• The "26 GAUGE" Stamp: Metal thickness, which is exactly 0.018 inches thick.
1. This is Standard Residential "Tin" (Not Heavy Commercial)
Duct has 90-degree TDF flanged ends (which are usually seen in high-pressure commercial environments), 26-gauge steel is thin for a main 20x16" commercial trunk line.
• According to SMACNA (Sheet Metal and Air Conditioning Contractors' National Association) standards, a rectangular duct width of 20 inches under standard commercial pressure typically requires a thicker 24-gauge metal.
• Because this piece uses thinner 26-gauge steel, it was likely built for a low-pressure application, such as a premium residential zoning system, a large home return-air drop, or light commercial supply lines.
Galvanized Steel
The "CSI" stamp explicitly confirms the material is galvanized steel rather than aluminum or stainless steel, as CSI specializes in zinc-coated (G-60 or G-90) structural steel panels
