ArcelorMittal Dofasco

What ArcelorMittal Dofasco does

ArcelorMittal Dofasco is Canada's largest steel producer and Ontario's largest private-sector employer, operating an integrated flat carbon steel manufacturing complex on 800 acres in Hamilton, Ontario. Founded in 1912 as Dominion Steel Castings Co. and now a wholly-owned subsidiary of ArcelorMittal S.A., the company produces approximately 4.5 million tonnes of flat carbon steel annually across roughly 130 grades. Its manufacturing footprint spans the full flat steel value chain: blast furnaces, basic oxygen steelmaking, hot and cold rolling, hot-dip galvanizing, aluminizing, coil coating at the Baycoat pre-paint facility, and tinplating for food packaging. The company supplies automotive, construction, energy, packaging, agricultural, and transportation infrastructure customers across North America, with a diverse product portfolio including the proprietary Usibor press-hardenable steels, Galvalume coated products with 40-60 year warranties, and the XCarb recycled/renewably produced steel line.

The business model is industrial B2B: products are sold via direct enterprise sales relationships with major OEMs, complemented by a customer e-commerce portal (ec.dofasco.ca) offering downloadable PDF price lists and ordering for direct customers. Pricing is quote-based on a per-tonne unit basis across hot rolled, cold rolled, galvanized, galvalume, tinplate, aluminized, and pre-paint product lines, with XCarb sustainable products sold at premium pricing. The company holds industry-critical certifications (ResponsibleSteel, IATF 16949, ISO 9001/14001/45001/50001) that gate access to tier-1 automotive and food packaging customers, and operates an in-house R&D Centre with over 80 researchers connected to ArcelorMittal's global network of 12 R&D centers and 1,500 researchers. A $2 billion decarbonization plan, roughly $500 million in government co-funding, and partnerships for biocarbon (CHAR Technologies, CanmetENERGY, CISERA) and digital transformation (Mohawk College) shape the forward capital allocation strategy.
