Galvanised tanks are water tanks manufactured using heavy-duty galvanised steel. While galvanised steel is similar in functionality as Aquaplate and other steel tanks used for water storage, they have a thick zinc coating making them less prone to moisture reducing the risk of weathering and external damage. The tanks also have an inner ploy lining which prevents rust and corrosion from the stored water and avoids leakage at welding joints and any other weak areas on the surface.
