The Detroit Iron & Steel Company was a predecessor to Great Lakes Steel Corporation and in 1902 built a
greenfield blast furnace plant on
Zug Island, the first modern blast furnace plant in the state of Michigan. The company was incorporated in Michigan on April 24, 1902, and issued 75,000 par $10 7% preferred and 75,000 par $10 common shares (split 2-for-1 on July 16, 1917).

Issued $600,000 15-year 5% bonds dated July 1, 1909 (at construction of second blast furnace), due annually $40,000 till July 1, 1925.

M. A. Hanna & Co •
Solvay Process Company (owned 30
adjoining byproduct coke ovens) • Detroit capitalists The furnace had a capacity of 300 tons of foundry iron per day, 30 additional coke ovens were built concurrently and there were plans to eventually have 180 ovens. This was the first modern coke-filled blast furnace built in the state of Michigan. There were 120 coke ovens in 1905. The furnace was blown in on February 15, 1904 and in 1911 rebuild as a modern thin-lined, water cooled furnace. The B furnace (80x18.5ft; 300tpd,
Arthur G. McKee type), directly adjoining to the east of A, was begun in early 1909 and blown in on July 21, 1910. The plant was located on the north east corner of the island. In 1917 the #Detroit Furnace Company was acquired. On May 1, 1920, the company was kicked off the Detroit Stock Exchange for failure to disclose operational and financial information. On November 1, 1920, Detroit Iron & Steel was among several companies that merged to form the
Hanna Furnace Co. (Delaware). Its two blast furnaces had a capacity of 685 tons per day. The furnaces were relined: No. 1 in 1905, 1909, ...
Pig Iron Industry in Michigan There were only 3 coke-burning blast furnaces in total in the state of Michigan (December 1914). The
Wayne furnace (''''
) of the Detroit Furnace Company
was a small 62 feet high 75tpd hand filled coke furnace with pipe stoves more resembling a typical charcoal furnace. It had existed in one form or another since originally built in 1870. The Detroit Furnaces Co. when incorporated on April 1, 1906, with $150,000 in capital took it over as a charcoal furnace. The company was acquired by Detroit Iron & Steel in 1917. The furnace went out of blast for the last time in the fall of 1919 and was dismantled to make room for a power plant of the Detroit City Gas Company''. Michigan as the second largest producer of iron ore in the United States had however about a dozen charcoal furnaces in operation and ranked about 7th in pig iron production (1916).
