TimberTanks are round wood storage tanks and for containment of other liquids and some solid materials. TimberTanks wood tanks are also used for signage, bulk storage and enclosures. TimberTanks water storage tanks combine the ageless beauty of wood with the durability of galvanized steel roofs and the modern technology of flexible membrane liners for water containment. The TimberTank structure consists of a wood stave barrel bound with galvanized wire rope wrapped around the barrel to complete the structure. The galvanized steel roof incorporates factory formed and punched high-rib roof panels which bolt together to create a weatherproof roof structure. Water containment is achieved with geotextile preliners installed within the wood barrel and a factory welded seam flexible membrane liner suspended inside the tank.
Georgia Water Tanks keeps an inventory of Texas Metal Tanks, 300 – 500 gallon sizes. Texas Metal Tanks manufactures both traditional galvanized steel cisterns and stainless steel cisterns. The galvanized steel tanks are G-90 grade 20 gauge metal made in the USA. We do not import foreign steel. The top is 22 gauge. After the tank is constructed, a paint / epoxy lining is applied to the interior of the tank to provide a protective barrier between the water and the metal itself. This product is FDA approved for potable (drinking) water applications and is ANSI / NSF 61 certified. Each tank is tested at the factory to ensure that it is watertight. With almost 90 years of history, these tanks have a typical lifespan of 30 – 35 years. Galvanized tanks have a one-year warranty.
