In 1882, Worth Brothers Company began operating a 90” rolling mill in Coatesville, greatly increasing the local competition.
For the next three decades, Worth Brothers and Lukens Iron & Steel Company competed for the widest rolling mill in the United States, and both were successful:
1890 Lukens 120”
1896 Worth 132”
1900 Lukens 134”
1903 Lukens 140”
1903 Worth 152”
The competition ended in 1915, when Midvale Steel and Ordnance Company acquired Worth Brothers. Then in 1918, Lukens put into operation the world’s largest plate mill.
