The Company’s founding predecessor 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 Corporation refocused its efforts and entered a range of growing markets, including components for the building and construction industries 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 Corporation 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.  The company further strengthened its role in the residential construction market during the 2000s with its purchase of Imperial Products, Truseal Technologies and Mikron Industries, all leading suppliers to the window and door markets.

In 2008, Quanex Corporation separated its steel and building products assets, and spun off the building products business to its shareholders as part of a brand-new company called Quanex Building Products Corporation.  The steel business was then sold, and is not part of our business today.

Since its creation in 2008, Quanex Building Products has continued to strengthen its dedication to the residential building and construction markets through numerous high-profile acquisitions, including Edgetech I.G., Alumco, HL Plastics, and Woodcraft Industries.
Today, Quanex Building Products is an industry-leading supplier of cutting-edge energy-efficient window and door systems, insulating glass spacer, kitchen and bath cabinet components, window screens, and various other building product components.
Employing top talent, as well as developing forward-thinking technologies and solutions with an emphasis on energy efficiency and aesthetics, continuous improvement, and integrity remain cornerstones of the Quanex 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.
