HarbisonWalker International (HWI) is a refractory solutions provider headquartered in Pittsburgh, Pennsylvania, USA. It combined its operations with Calderys in 2023 and became the group's brand for the Americas region.
HarbisonWalker International (HWI) was created by the merger of Harbison-Walker, A.P. Green, and North American Refractories, all considered among the Big 5 of the firebrick industry during the first half of the 20th century. [n 1] [1]
The Harbison and Walker Company was founded in Pennsylvania in 1875 when Hay Walker Sr. and Samuel P. Harbison bought the company Star Fire Brick Company founded 10 years earlier. Harbison-Walker Refractories was acquired by Dresser Industries in 1967 [2] but demerged from Dresser in 1992. [3] [4] In 1999, Harbison-Walker managed 4,000 employees and 25 locations in 7 countries (15 production sites in the USA, 3 in Canada) when it was acquired by the Austrian conglomerate RHI Refractories. [5]
Missouri-born Allen Percival Green (1875-1956) worked temporarily for Harbison-Walker Refractories Company, and then bought the Mexico Brick and Fire Clay Company in 1910. The A.P. Green Fire Brick Company grew strong during World War I and World War II. A.P. Green's company went public on the New York Stock Exchange in 1966, and was taken over by Gypsum (USG) in 1967. [1] [6] It was then acquired by RHI AG.
North American Refractories Co. (NARCO) was created in 1929 in Ohio through the merger of seven manufacturers of refractory solutions. NARCO was acquired by Eltra Corp. in 1965. Eltra Corp. was acquired by Allied Corp. in 1979, making NARCO part of Allied's chemical division. NARCO was then owned by Didier-Werke AG of Wiesbaden in 1989 and sold in 1995 to the Austrian group Veitsch-Radex in 1996, a subsidiary of RHI. [7]
In 2002, many US refractory companies - including Harbison-Walker, A.P. Green, and North American Refractories - were embroiled in the abestos claims and filed for bankruptcy. [8] RHI had combined its US subsidiaries under the RHI Americas banner, which spun off after the bankruptcy and became ANH Refractories Company in 2002. [9]
In 2015, ANH Refractories changed its name to HarbisonWalker International (HWI). [10] In 2023, a US private investment firm acquired HWI and combined its operations with its other refractory company Calderys, [11] with the new name "HWI, a member of Calderys" and acting as the Americas' arm of Calderys.
