Quanex was founded in 1927 as a Michigan corporation under the
name of Michigan Seamless Tube Company (MST). Its principal
operation was redrawing used boiler and condenser tubes for resale
as refrigeration tubing.
From the beginning, the company's strategy has
remained constant, while its products have changed to meet customer
needs. Quanex has steadily grown its business by focusing on
specialized, manufacturing processes to produce
value-added products for original equipment manufacturers.
At first, the company's growth came from internal expansion.
Capital improvements added to capacity and capabilities,
and sales topped $1 million for the first time in 1935.
The company's foray into external expansion began in 1956 with
the construction of a greenfield tubing plant located in Rosenberg,
Texas. In the 1960's MST made its first acquisitions, purchasing
tubing and tooling manufacturing plants in Ohio, Michigan, and
During the 1970's, raw material supply problems began to affect
the company's tubing operations. To resolve this issue, plans were
made to build a greenfield plant in Jackson, Michigan, that used a
unique centrifugal continuous casting process to make high quality,
seamless steel bars for the company's tubing mills. Production from
the original MACSTEEL mill began in 1974.
MST's growth moved forward with the purchase of other
specialized metal manufacturing companies and the sale of
operations no longer aligned with the company's evolving strategy.
To be closer to its primary customers, which were based in the
energy industry, the company moved its headquarters from Michigan
to Houston, Texas, in 1977, and the name was officially changed to
Quanex. The name means "quality connection", tracing its origins to
the combination of the word "quality" and the Latin word for
Both internal and external growth continued in the 1980's with
the construction of new plants, acquisition of plants and
facilities dedicated to diversified manufacturing and processing
operations, and capital expansion programs at the company's
existing facilities. Production from MACSTEEL's Fort Smith plant
began in 1985.
As part of the company's strategy to diversify, Quanex entered
the aluminum business in 1989 with the acquisition of
Nichols-Homeshield. Construction of an innovative, scrap-based
mini-mill for the manufacture of aluminum sheet began in 1990, with
production beginning in 1992.
With the addition of its aluminum products business, Quanex
began its strategic transition to become not just a steel producer,
but a manufacturer of specialized metal products.
Over the next ten years, the company grew its building products
operations, purchasing Imperial Products in 2000, Colonial Craft in
2002, Truseal in 2003 and Mikron in 2004. In April 2008,
Quanex Corporation spun off its building products operations and
Quanex Building Products Corporation officially began. The
steel operations were subsequently sold to Gerdau S.A., a global
steel producer. Quanex's tradition of growth through
internal and external expansion continued. Celebrating its
75th year in business in 2002, the company adopted a market
driven strategy with concentration on customers in two segments -
Aluminum Sheet Products and Engineered Products.
Quanex Building Products most recent acquisition of Edgetech,
exemplifies the company's strategy of becoming the leading
manufacturer of fenestration systems and components, recognized for
product technology and innovation, and best in class customer
service. Quanex is committed to partnering with customers and
proactively developing innovative and energy efficient fenestration
