Officials welcomed the county's newest industry, Amesbury Extruded Products, to town Monday afternoon, hosting a ceremonial ground turning in the 45,000 square foot building shell at 13170 Lochridge Blvd. The plastics extrusion company hopes to open its newest manufacturing plant by January, said Plant Manager Tim McCormick. The plant will represent an initial investment of $4 million. Pattillo will complete the building at a cost of $2 million, while Amesbury will bring in $1.3 million in assets and invest another $300,000 in the building.
