The plant operates two 8-hour shifts with 250 heavy metal fabrication specialists including machine operators, welders, and painters. The fabrication and painting area covers approximately 200,000 square feet.In part of the facility, ladders and other components used on fire and rescue vehicles and other heavy equipment are fabricated and painted. The East paint shop, used for painting ladders, includes a large side-draft paint booth, drying oven, prep and finish area, and a separate room for touch-up work.
