TrentonWorks is an industrial manufacturing facility located in the town of Trenton, Nova Scotia, Canada.
This collection of factories on the bank of the East River of Pictou has witnessed a large variety of industrial operations, ranging from steel making (the first steel plant in Canada), rolling mills, forging, shipbuilding, munitions manufacturing, rivets and bolts, and most recently (and longest lasting) rail cars.
The extensive plant is being converted to manufacture wind turbine components for South Korean industrial conglomerate Daewoo Shipbuilding & Marine Engineering in its first foray into North America; this is being made possible through corresponding investments by both the Government of Nova Scotia and the Government of Canada.
The Hope Iron Works was founded at Trenton by blacksmiths Graham Fraser and Forrest MacKay in 1872 to produce iron forgings such as anchors for use in wooden sailing ships with the business expanding in 1876 to produce railway car axles.
In 1878 the Nova Scotia Forge Company was constructed on a 160-acre (0.65 km2) site occupying the east bank of the East River of Pictou in Trenton, replacing the Hope Iron Works. The new plant sought markets in producing forgings for the booming railway industry, creating an intense demand for raw steel and iron. The Nova Scotia Steel Company was established in 1882 on the same site to supply raw material to the Nova Scotia Forge Company and produced the first steel in Canada at its Trenton plant using the Siemens process in an open-hearth furnace in 1883. Both companies soon merged to form the Nova Scotia Steel and Forge Company.
Initially the steel mill at Trenton was fed by scrap metal and pig iron imported from Scotland however shortages in scrap saw the New Glasgow Iron, Coal and Railway Company construct an oxygen blast furnace at Ferrona in the upper reaches of the East River valley that would be supplied with iron ore mined at Eureka and Londonderry. Coke was supplied by local coal mines in Stellarton, Westville and Thorburn. These sources of iron ore were soon found to be high in manganese, thus higher quality iron ore was soon discovered at Wabana on Bell Island, Newfoundland which was then shipped to the Ferrona blast furnaces. In 1895, the New Glasgow Iron, Coal and Railway Company purchased rights to some of the Wabana ore deposit for a long-term supply.
