Calderys is a privately-owned company of refractory solutions headquartered in Paris, France. It resulted from the merger of the refractory companies Plibrico and Lafarge Réfractaires in 2005, and combined its operations with HarbisonWalker International in 2023.
History
[edit]William A.L. Schaefer, in 1914, developed the first monolithic refractory and created the Pliable Firebrick Company, which is also known as Plibrico. Plibrico developed its presence throughout Europe from 1930 to 1960, and was acquired by the group Imetal (future Imerys) in 1996.[1] Imerys also acquired Lafarge Réfractaires from Materis in 2004.[2]
In 2005, Imerys merged Plibrico and Lafarge Réfractaires to create Calderys.[3] Imerys pursued Calderys' global expansion with acquisitions such as ACE Refractories in India in 2007.[4][5] Later next year in 2008, Svenska Silikaverken AB, a monolithic company active in Sweden, Norway and Finland, was acquired by Calderys, as well as Valöns, an important quartzite source in Åmål, Sweden.[6] In early 2013, Calderys acquired Arefcon b.v., a refractory installation company based in the Netherlands for the petrochemical industry.[7] The company continued its expansion in Asia in 2013 by signing a joint venture agreement with PT Indoporlen, an Indonesian refractory manufacturer and service provider,[8] as well as by acquiring Tokai Ceramics, a Japanese refractory producer.[9] In 2014, Calderys acquired Termorak Group in Finland (refractory services including lining design, installation work and inspections).[10] It acquired Kerneos in 2017.[11]
In 2023, Imerys sold Calderys to a US private investment firm for 930 million euros.[12] After the acquisition, Calderys became a standalone company.[13] The fund also acquired HarbisonWalker International and combined its operations with Calderys.[14]
