From essential infrastructure like bridges to the pipes that serve the energy sector, steel is a critical component of the economy. Many of the steel companies in Canada come from humble roots, often just a handful of people, a welding machine and a truck. Some have grown into international giants that are tackling some of the most complex projects in the world. Here are just a handful of those companies with compelling backstories.

Algoma Steel

Algoma Steel was forged in 1901 with two small blast furnaces, a 60-ton Bessemer furnace, a 23- inch bloom rolling mill and rail mill. It has since grown into a fully integrated steel producer based in Sault Ste. Marie, Ont. The company manufactures and sells hot and cold rolled steel products including sheet and plate. The company is currently constructing two new state-of-the-art electric-arc-furnaces to replace its existing blast furnace and basic oxygen steelmaking operations. It’s the biggest construction project in Sault Ste. Marie history. The change is expected to reduce Algoma’s carbon emissions by 70%.

The group recently won an award for its Building Engineering Platform (BEP) which aims to modernize, update or replace some in-house engineering and detailing applications for Canam’s steel products.

Solid Rock is a classic immigrant success story. Berend Steunenberg learned the metal fabricating trade while growing up in Holland and and took his skills to Vancouver in the 1950s. He worked day and night shifts at two jobs to buy an old flat deck truck, a second-hand welding machine and a torch set-up to start Solid Rock Steel. Now the company is helping tackle large, complex projects like The Butterfly, the Surrey Central Library and Microsoft’s Vancouver headquarters.

Originally called the Steel Company of Canada, Stelco was created in 1910 via the merger of Montreal Rolling Mills, the Hamilton Steel and Iron Company, and a handful of secondary companies located from Gananoque to Brantford. The company shifted its production during WW1 and WW2 to help with the war effort. Today it serves the construction, automotive, energy, appliance, and pipe and tube industries.
