The founding company was incorporated in 1927 under the name Michigan Seamless Tube Company in South Lyon, Michigan. After steady gains through the 1950s and 1960s and the acquisition of Standard Tube, the company was first listed on the New York Stock Exchange in 1965. By this time, Michigan Seamless was producing steel in several states and had diversified to serve a variety of industries.
The acquisition of MacSteel in 1974 proved to be a major milestone as the company set its sights on the booming energy sector. To reflect the company’s growing markets and product diversity, its name was officially changed to Quanex Corporation in 1977.
Throughout the 1980s, Quanex refocused its efforts and entered a range of growing markets, including components for the building and construction and aluminum sheet coil production through the acquisition of Nichols Homeshield. The company also continued expanding its geographical distribution of specialized steel used in agricultural machinery and transportation. It was during this time that the company’s heavy focus on efficiency, state-of-the-art production and unmatched customer support began.
Quanex experienced great success throughout the 1980s and 1990s through a number of strategic moves to define the company's focus on its role in the vehicular products and building products segments. Over the last decade, Quanex strengthened its role in the residential construction markets with the purchases of Imperial Products, Truseal Technologies and Mikron Industries, all leading suppliers to the window and door markets.
By making a number of strategic moves to define the company's focus on its role in the vehicular products and building products segments, Quanex experienced great success throughout the 1990s.
During the 2000’s, Quanex strengthened its role in the residential construction markets with the purchases of Imperial Products, Truseal Technologies and Mikron Industries, all leading suppliers to the window and door markets.
In 2008, Quanex sold its steel business and renamed the company after its remaining assets, Quanex Building Products Corporation. The company continued to strengthen its dedication to the residential building and construction markets through two more high-profile acquisitions, Edgetech I.G. and Alumco. In 2015, it made two more strategic acquisitions, through HL Plastics and Woodcraft Industries.
Today, Quanex is an industry-leading supplier of cutting edge energy-efficient window and door systems and building product components.
Employing top talent, developing forward-thinking technologies and solutions with an emphasis on energy efficiency and aesthetics, continuous improvement and integrity remain the cornerstones of Quanex’s business as it positions itself for future growth in the building products market with a special emphasis on supplying innovative new products to the industry.
