Elkhart, Ind.-based Postle Aluminum Co. announced that it has begun construction of a new extrusion plant in Cassopolis, Mich.

The $8 million dollar expansion, including plant and equipment, will be located on four acres next to the company’s existing campus. The plant will encompass 60,000 square feet and result in the addition of 40 new jobs to Postle’s existing workforce.

CEO Kevin Robinson said Postle broke ground in August and expects completion and startup of the project in March 2015.

“Postle is growing and this expansion will help to support the continued growth of the RV industry,” Robinson said.
