One of the most common dilemmas when selecting an above ground storage tank is whether steel tanks or plastic tanks offer the best advantage for storing water, chemicals, or petroleum. In this article, we will examine the benefits and drawbacks of each type of tank and offer advice on how to make the best choice.
Steel is durable and resilient, meaning these tanks can survive harsh weather, such as severe storms, heavy rainfall, and earthquakes. Tanks constructed of steel, specifically those to the UL 2085 Fireguard design, are ideal for wildfire-prone locations. Additionally, steel is a popular option for commercial or industrial applications since, unlike plastic, it can withstand bugs, pests, rodents, and wild animals.
One common concern with steel is the factor of corrosion and rust over time. Keep in mind that corrosion and rust can be prevented with proper maintenance. Another benefit of steel is that the tank may be painted to blend in with the surroundings or coated internally to prevent corrosion. Durable interior and exterior coatings in a tank constructed from mild carbon steel can make it suitable for storing corrosive products, eliminating the need for expensive stainless steel.
Plastic tanks can deteriorate over time due to their vulnerability to UV rays. Deterioration is one of their most significant drawbacks because, in many cases, it is difficult to prevent. The deterioration may result in leaks and cracks, which can create substantial costs due to the product being stored, becoming contaminated, or the environment being polluted from a spill.
The weight of steel is a significant drawback. Because steel is heavier than plastic, installing and transporting the tank may take more work. However, new shipping and crane technologies have made transportation and lifting more cost-efficient. Lastly, the cost difference between a steel and plastic tank can be a deal-breaker for individuals with limited funds. Therefore, it is essential to consider the cost in the long run instead of the initial purchase cost. In addition to being less resilient than steel, plastic tanks may require more frequent replacements.
When choosing between a plastic tank and a steel tank, it is crucial to thoroughly analyze the advantages and disadvantages, your budget, and unique demands. Considering the cost in the long run is also crucial. Regular maintenance is necessary regardless of whether you choose a steel or plastic tank. While plastic tanks offer a lower cost and easier installation, the costs over time could possibly exceed those of a steel tank.
