Kitchen Exhaust Duct — Black Iron & Stainless Fabrication

Custom kitchen exhaust duct fabricated at MaticAir in black iron and stainless steel. Built to your drawings, same day, for restaurants and commercial kitchens across the GTA.

Why black iron

Code-grade grease exhaust, built right.

Ontario Fire Code Requirements

Commercial kitchen exhaust duct in Ontario must be constructed of steel not less than 1.37 mm (0.054") thick — equivalent to 16-gauge minimum — with continuously welded seams. Black iron meets these requirements and is the industry standard for grease duct.

Automatic Welding for Consistent Seams

MaticAir's automatic black iron welding equipment produces continuous, code-grade seams on every run. No gaps, no spot welds on critical joints — the seam is consistent whether we're building 5 feet or 50.

Stainless Option Available

For applications requiring stainless steel — high-humidity environments, certain health code applications, or client specification — we fabricate in 304 and 316 stainless. Call Ext. 218 for a quote.
