SIOUX FALLS, S.D. — A Maine-based manufacturer of aluminum trailers plans to open a plant in South Dakota’s largest city.

The Governor’s Office of Economic Development says the Alcom LLC plant in Sioux Falls will create 20 jobs initially and up to 180 positions in the next three years.

Alcom hopes to be making trailers in early April in the former 54,000-square-foot Balance Systems Inc. building in the northern part of the city.

Alcom CEO Trapper Clark says the manufacturer has 250 employees in Winslow, Maine, and opened a plant in Missoula, Mont., last year that employs 70 people. He says Alcom is expanding to South Dakota because of building and workforce availability, its central location and its pro-business climate.

The state will provide $90,000 in workforce development money to assist with training costs.
