Alan Zekelman owns a stake in his family’s steel business, Zekelman Industries. The $2.8 billion (revenues) company is one of North America’s largest steel pipe and tube makers. Alan and his brothers, fellow billionaires Barry Zekelman and Clayton Zekelman, split 100% ownership of Zekelman Industries. They sold the company to the Carlyle Group in 2006 for some $1.2 billion, but bought the business back in 2011. One of Zekelman Industries’ subsidiaries, Atlas Tube, is producing steel for the stretches of the Mexican border wall going up in Arizona.
