Steel pipe manufacturer Wheatland Tube is closing its plant on the south side of Chicago and laying off more than 230 employees.

According to the Chicago Tribune, the layoffs will begin on November 1 and continue throughout next year. Wheatland did not provide an anticipated date for the factory’s closure.

The company, which is a subsidiary of the nearly 150-year-old Zekelman Industries, is headquartered in both Illinois and Wheatland, Pennsylvania, and operates additional plants in Ohio, Alabama and Missouri. In a statement obtained by the Chicago Tribune, Wheatland said it has no plans to shutter any of its other factories.
