He paid particular attention to the works at Saint-Chamond and Assailly, where he developed the special fabrications that brought fame to the factories.
At Saint-Chamond he built a forge that could make 80-ton ingots, and he installed a great steam hammer with a 100-ton ram.

He developed arms manufacture at Saint-Chamond, and also delivered large quantities of rails to major French railroad companies.
