Welded Duct Work

At Airtilize Inc., we understand that properly designed and welded commercial kitchen ductwork is essential for fire safety, grease containment, and regulatory compliance. Our comprehensive welded ductwork services are designed to meet your unique ventilation needs, providing solutions that are durable, code-compliant, and engineered specifically for your kitchen’s hood system, exhaust fan location, and building structure.

We offer end-to-end services, starting from detailed engineering and shop drawings. Our experts create CAD drawings showing every component, weld location, support point, and penetration. We calculate proper duct sizing based on CFM requirements, plan optimal routing to minimize horizontal runs, specify appropriate materials and gauges, verify clearances to combustibles, and design complete drainage systems with proper slope. Whether you need 16-gauge Type 304 stainless steel for standard applications or 14-gauge Type 316 for coastal environments, we have the technical expertise and fabrication capabilities to deliver the right solution.

In addition to new installations, our team provides ductwork inspection and upgrade services aimed at identifying code violations and safety hazards in existing systems. We evaluate structural integrity, check for grease accumulation and leakage, verify proper slope and drainage, assess access panel placement, and identify non-compliant materials or construction methods. Our assessments help restaurant owners understand their risks and plan necessary upgrades to avoid citations and ensure safety.

Should you need duct replacement or retrofit services, Airtilize Inc. is ready with efficient installation that minimizes operational disruption. Our certified installers work during off-hours when possible, provide temporary exhaust solutions if needed, complete installations quickly with experienced crews, coordinate all permit and inspection requirements, and ensure your kitchen passes final fire marshal approval. We handle everything from removing old ductwork to installing new code-compliant systems with proper supports and firestopping.

We specialize in precision TIG welding that creates liquid-tight, smooth interior joints meeting all NFPA 96 requirements. Our ductwork features continuously welded longitudinal seams, full-penetration welds with no internal spatter, minimum 2% slope toward cleanout points, UL-listed access panels every 12-20 feet, engineered hanger spacing with seismic bracing where required, and proper fire-rated penetrations at all wall and floor crossings. Every installation includes complete documentation, as-built drawings, and inspection coordination.

With over 20 years of experience in commercial kitchen ventilation and hundreds of successful ductwork installations across Ontario and beyond, we are confident in delivering welded duct systems that pass every inspection, prevent grease fires, operate efficiently for decades, and provide complete peace of mind.
