Our exciting announcement is out! Preload has finished the expansion of the Mechanics and Fabrication Shop building. This expansion represents part of Preload’s future. But first, here is some valuable history of the Mechanics and Fabrication Shop building to know. For many years this structure served as a storage and base for Caldwell Tanks’ coatings division. In 2017, Preload converted the storage facility into a Mechanics and Fabrication Shop. In 2018 Preload began stocking commonly used tank construction items in the building for shipment to projects around the country.

Expansion Specifications:

The expansion took under two years to complete and serves two primary functions for Preload. These functions are inventory storage and fully enclosed diaphragm and closure plate production. The new building allows for high capacity storage racks since the ceilings are 20 feet high to the cross beams. Additionally, the expansion roughly doubled the size of the existing building. In other words, the expansion added over 6,500 square feet.

The building stores commonly used tank inventory, including construction materials such as curing compounds, miscellaneous fasteners, round stock, and specialty tools. This insulated structure stores any temperature-sensitive inventory to prevent extreme weather damage.

Several customized shipping containers store other various tools and inventory outside the Mechanics and Fabrication Shop building. These containers are not temperature controlled. Thus, these containers do not store temperature-sensitive contents. The main inventory items found in these containers include miscellaneous job supplies and rigging gear.


With more than 3,700 tanks completed to date, PRELOAD is the global pioneer of wire-wound prestressed concrete storage tanks. Since the construction of our first wire-wound prestressed concrete tank in the 1930s, we have been innovators in our industry. Additionally, PRELOAD serves clients across the United States with offices in Kentucky, New York, Texas, and Massachusetts.
