context_page_description: The Tréfileries et Laminoirs du Havre was an enterprise based in Le Havre, France, that manufactured copper wire, other copper products and products of other metals including bronze and aluminum.
  It was founded to serve the rapidly growing market for electrical power transmission and for telegraph and telephone cables.
  It grew into a massive industrial empire with factories in many French cities and abroad.
  In 1962 it merged with the Compagnie française des métaux and became Tréfimétaux.
  In 1967 Tréfimétaux was acquired by Pechiney. The various plants were closed or sold over the years.
context_section_description: The company later moved its headquarters to Paris and came to have factories in Le Havre, Rugles, Saint-Maurice, Grenoble, Charleval, la Praz, Dijon, Montreuil-Belfroy, Darnétal, Saint-Denis, La Courneuve, Poissy and Pont-de-Chéruy.
  Eugène Mauclère (1857–1933), former controller-general of the army and councilor of state, a member of the board of the Chemins de fer de Paris à Lyon et à la Méditerranée and vice-president of the Mokta-el-Hadid and Phosphates de Gafsa mining companies, joined the board of TLH as president in 1931.
  In 1932 TLH was the largest manufacturers of copper, lead, zinc, tin and metal products in Le Havre, which now received 60% of copper imports into France thanks to its connections with North America.
  The plant made wire, tubes and sheets of copper and steel which were then shipped to the mechanical construction and electrical industries.
  A quarter of output went to the colonies.
  As of 1939 TLH employed 4.673 workers in Le Havre.
  During World War II (1939–45) in the period between 1940 and 1944 TLH had to deal with a shortage of copper, and made more use of aluminum and aluminum alloys.
  From 1943 Henri Lafond was President of the Mines du Huaron and on the board of Tréfileries et Laminoirs du Havre.
  A 1952 study said Trefileries et Laminoirs du Havre had a capital of 3,132 million francs and holdings in Hauts Fourneaux de la Chiers, Alais-Froges, Financiere Metallurgique Electrique, Lignes Telegraphiques et Telephoniques, Etablissements Bouchery, Signaux et Entreprises Electriques, Etablissements Coquillard and the Societe Procol.
  TLH was also part-owner of  Pechiney.
