Our galvanized water trough are fabricated at our state-of-the-art manufacturing facility dedicated to the production of water tanks. 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. 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 leaking tanks 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 adhesive/sealant seam sealer for a superior bond.
