Thomas Ziegler

President of Operations

Thomas Ziegler has over 40 years of experience in the aluminum extrusion and fabrication industry and has been with Gateway Extrusions since 2006. In 2017, Ziegler was named President of Operations. He has directed progressive company expansions, added experienced managers and employees, and he has been instrumental in developing new markets for the company’s extrusion and finishing services. Since 2014, the company’s workforce has doubled to 130 employees, the factory’s production has doubled to over 12.8 million pounds of aluminum processed in 2017, and production for 2018 is expected to be over 16 million pounds.

Under Ziegler’s leadership, Gateway has expanded from exclusively serving its parent company to serving many companies in a broad array of industries such as automotive, shelving and storage, office furniture, displays, marine transportation, fencing and railing, lighting, and other window and window accessory manufacturers. Gateway has customers in nearly 30 states across the country.

Starting in 2015, Ziegler has been responsible for leading another significant multiyear phased expansion of the company. Gateway acquired its existing building which it had been leasing and bought the adjacent property for future expansion. The company invested in significant building renovations, purchased and installed new 7-inch and 9-inch aluminum extrusion presses. A major addition to the factory was built to accommodate a new vertical powder coat paint line that was installed in 2017. Further property improvements are underway.

Prior to joining Gateway Extrusions, Mr. Ziegler held positions of progressively greater responsibility at Alcoa; most recently he was Operations Manager for Alcoa’s 500,000 square foot extrusion manufacturing facility in Georgia. There he directed the production of 50 million pounds of aluminum building and construction products annually, increasing employee involvement and improving safety. Also while with Alcoa, he led the conversion of an existing Mississippi aluminum extrusion plant into an architectural storefront systems manufacturing facility.

Ziegler is an active member of The Aluminum Extruders Council, a national industry trade organization, where he previously held leadership positions. He is also active with local business and community organizations in the City of Union and Franklin County, MO.
