Whether you're constructing a modest rainwater collection system or an industrial-scale water treatment plant (or anything in between), you will need durable, reliable water tanks for storing your precious liquids, and choosing the right material for your next water tank can often mean the difference between a useful tank and a rusting, leaking mess. A wide variety of materials are used to fabricate water tanks, from inexpensive thermoplastics to formidable concrete, but one of the most versatile materials used to make water tanks is stainless steel.
This unique and high-prized metal seeing use in a wide variety of structures and components, but is particularly well suited to water tank fabrication, and sheet metal fabrication services routinely make water tanks both large and small from this unique metal. Here are just some of the advantages choosing stainless sheet steel for your water tank can offer:
Unlike conventional steels, stainless steel is actually an alloy, with small amounts of chrome and other metals mixed into the steel during the forging process. These small additions have a big effect, and make stainless steel completely immune to the rust and corrosion that can swiftly cause damage to regular steel and other ferrous metals.
As you can imagine, this rust resistance is extremely useful when it comes to water tanks, and a stainless steel water tank can hold heated and even contaminated water without suffering from corrosion. This immunity is not affected if the tank is exposed to the elements, making stainless steel a popular choice for large, industrial water tanks in outdoor locations.
As well as providing excellent protection against rust, stainless steel can also take a serious beating, as it retains the strength of the mild steel that makes up most of its composition. This places it in stark contrast to other rustproof metals, such as aluminium or copper, which have significantly reduced strength and durability and can easily buckle under heavy loads or high pressurisation. Stainless steel also has excellent load-bearing strength, so multiple stainless steel tanks can be safely stacked to save valuable space.
Stainless steel water tanks are especially popular for food-grade applications and potable water storage -- unlike some plastic or cheaper metal tanks, they do not release any oxides or contaminants into the water held within, even after long periods of stationary storage. Stainless steel tanks are also very easy to clean (both inside and out), and its chemically inert nature minimises the risk of harmful chemical reactions if your stored water has an unusually high or low pH.
Plastic water tanks generally have to be thrown away once they have degraded past the point of use, while concrete tanks have to be broken up and made unusable prior to their removal. By contrast, a stainless steel water tank you no longer need can easily be repurposed, with the lack of any rust build-up helping your tanks keep their value even after long periods of service. If your stainless steel tanks do become unusable due to physical damage, recycling centres can easily melt them down for use in other products, so stainless steel also represents a fairly environmentally friendly choice of tank material.
