Jefferson City Facility

DeLong’s has two manufacturing facilities, one located in Jefferson City and the other in Sedalia, Missouri with nearly 200 employees between the two sites.  Due to growth in recent years, we have also opened an off-site storage facility located just a few miles from the main plant.  We now have over 450,000 square feet under roof and almost 345,000 square feet under crane.  We have two climate controlled, state-of-the-art paint facilities.


The Jefferson City plant has 450,000 square feet under roof and approximately 345,000 square feet under crane.
