Our Galvanized Stock Tanks are fabricated at Liberty Water Tanks, our state-of-the-art manufacturing facility dedicated to the exclusive production of water tanks. Our rigid standards and unparalleled manufacturing acumen combined with the finest high-quality steel and outstanding value make these the best galvanized tanks around. We take flat, rolled steel, coated with heavy-duty zinc G90, cut it into precise lengths, then guide it into shape on computer-driven forming mills that make the world's best galvanized water tanks at a faster rate and with few chances for human error ever. The formed tanks are matched to precision-cut bottoms, spot welded and joined by a computer-driven-and-guided seaming station that makes 3 circumferences around each tank bottom before the sealer is applied. Then, 3 or 4 sets of tanks per day are filled with water for testing purposes so that no leakers ever make it out of the plant. They feature 20-gauge galvanized bottoms and 21-gauge sides as well as a four-ply double-lock seam at the bottom sealed with Pliogrip Adhesive/Sealant Seam Sealer for a superior bond.
