A lan Zekelman, along with his brothers Barry and Clayton, is a principal owner of Zekelman Industries, one of North America's largest independent manufacturers of steel pipes and tubes. The company's roots go back to Atlas Tube, which was founded by their father, Harry Zekelman, in 1984. The brothers inherited the business and worked together to expand its scale and reach, becoming dominant players in the structural steel industry.

The family sold a majority stake in their company to the Carlyle Group in 2006, but in a bold move, they bought it back in 2011, regaining full control. Under the brothers' leadership, the company, renamed Zekelman Industries, has grown through strategic acquisitions, including the purchase of several other steel tubing companies. Alan has played a key role in the company's operational and strategic direction. The Zekelman brothers are known for their deep expertise in the steel industry and their commitment to manufacturing in North America.
