Large Water Tanks — Why You Should Upgrade From Steel to Poly

Steel tanks have been the traditional solution for commercial water storage. The material is incredibly sturdy and has been the preferred option for businesses seeking long-term water storage solutions. However, more people are becoming aware of the limitations that come with using steel. After several years, it becomes imperative to replace steel water tanks due to unavoidable damage, as the steel succumbs to years of use and exposure to the elements. As a result, a more enduring solution has emerged in the form of polyethylene water tanks. If you are planning to install large water tanks on your commercial premises, here are practical benefits of upgrading from steel to poly.

Roto-moulded poly water tanks are easy to retrofit

The first advantage of choosing to install poly water tanks over their steel counterparts is the ease of integrating the former in your business premises. What you may be unfamiliar with is how the installation process of steel water tanks entails multiple stages. First, a sturdy concrete base has to be erected to ensure that the bottom part of the steel water tank does not degrade from premature corrosion. Second, steel rings are mounted on the concrete base to be utilised for securing the tank in place. Polyethylene water tanks are far easier to work with, as all they require for their placement is a flat and even surface, void of any potential sharp objects that could pierce the tank.

Roto-moulded poly water tanks are not easily degradable

The biggest limitation posed by steel tanks is their vulnerability to corrosion—especially if you place your water tanks outdoor where they will be continually exposed to the erratic climatic changes in Australia. Without adequate shelter, the steel eventually begins to corrode, and the integrity of the storage tank will come into question. Polyethylene tanks, on the other hand, are designed to withstand the harsh conditions that the changing weather elements pose. The plastic will never corrode, so it is bound to serve you for several decades. In addition to this, the poly water tanks are manufactured with ultraviolet inhibitors. These inhibitors function to provide your water storage with UV protection, even during the scorching summer.

Roto-moulded poly water tanks are better adept at storing drinking water

Although steel water tanks work just fine for water used for external applications, they are not an ideal choice if you are ingesting the stored water. The interior linings of the steel tanks are coated with galvanised zinc, which can steadily seep into the water and change how it tastes. If you are using the water storage for consumption on your commercial premises, BPA-free polyethylene water tanks are a safer alternative.
