The Code-Required Standard for Kitchen Exhaust
Built for Demanding Environments
- High-Rise Office Buildings – Withstanding pressure differentials across multiple floors
- Upscale Retail – Premium construction matching premium spaces
- Mixed-Use Developments – Separating systems while maintaining acoustic control
- Historic Renovations – Modern performance in buildings requiring permanent solutions
Why Codes Require Welded Construction?
- Grease Fire Containment
Welded seams prevent grease-laden air from escaping into building cavities. If a duct fire occurs, continuous welds contain flames within the ductwork system. - Zero Leakage Tolerance
Kitchen exhaust can’t leak. Period. Welded construction eliminates every potential escape point that screws, rivets, or slip joints would create. - Structural Integrity Under Heat
Exhaust temperatures can spike during cooking operations. Welded 16-gauge construction maintains integrity when lighter materials would fail. - Long-Term Grease Exposure
Grease accumulation stresses duct seams over time. Welded joints don’t loosen, separate, or deteriorate like mechanical fasteners.
Welding Quality Standards
Continuous Seams – No skip welding or spot welds—complete penetration throughout. Smooth Interior Finish – Minimizing grease accumulation points inside ductwork. Clean Exterior Appearance – Professional welds that pass inspector scrutiny. Leak-Proof Connections – Every joint sealed completely against air and grease escape
Material Specifications
Commercial-Grade Steel – 16-gauge thickness throughout, no lighter sections. Galvanized or Black Iron – Material selection based on application and code requirements. Stainless Options – When corrosion resistance or premium appearance matters
