It all started in 1828

The company originated back in 1828 producing ornamental ironwork when George Cornell and Samul B Althause took over Benjamin Birdsall's business and formed Cornell & Althause, premier manufacturers of plain and ornamental ironwork. The early products included railings, fire-proof chests, grates, fenders, and bedsteads that feature, “durability and freedom from bugs”.

The origins of our security grilles began in 1854 when J.B. Cornell patents a method of joining metal slats for revolving shutters for store windows. J.B. and W. W. Cornell would continue developing new innovative products we have become world known for when J.B. Cornell patented a metallic surface for fireproof partitions that would support plaster. This invention enabled the construction of high-rise fireproof buildings. This same year, the brothers added a foundry to their plant.

After the death of W.W., a new partnership between J.B. and his son J.M. is formed, becoming one of the largest manufacturing operations in New York City, employing 1,200 at its peak. It provided steel and iron work for the Product Exchange, probably the largest ironwork contract ever given in New York City, The Havemeyer Building, The US Trust Building, and over 13,000 tons of elevated railroad structure for New York and Brooklyn Stations. The firm provided circular stairs and ironwork for the Brooklyn Bridge and the iron base and stairways for the Statue of Liberty. It was the largest customer of the Carnegie Steel Company at the time.

The rolling door industry leader through the 1900’s  

Throughout the 1900’s the company continued to expand and provide premier quality ironwork throughout New York City and beyond. As steel and pg iron production move west, the firm began to reduce its production of heavy iron for structural uses and focused on the rolling door business, which is the backbone of our production today. In 1911, J.M. Cornell forms a new company with his sons, Milton and John. Called Cornell Iron Works, it focused on the production of rolling door products.

In 1931, Cornell introduces the metal security grille or mall grille to the United States market. This replaces the wooden rolling grille which had become a staple in the industry. Through the thirties and forties Cornell produced wood sectional doors because steel was hard to afford during the depression and unavailable during the war. We discontinued this product line in 1952.

Relocation to Pennsylvania        

As production continued to increase, Cornell moved all production from its Long Island City plant to a newly built facility "out west" in Mountain Top, Pennsylvania in 1965.  As manufacturing outgrew the initial building, Cornell acquired the Oceana building across the street. With overhead door and security grille business still booming, Cornell opened a new 188,000 square-foot state-of-the-art production facility in Mountain Top, PA. The single location affords space for more efficient production methods, as well as room for future growth. The new facility is dedicated to M. Keen Cornell, president of Cornell from 1969 to 1997.
