Finding a reliable storage tank can be daunting for business owners with little expertise in tank selection. If you are trying to decide between the two most popular types of storage tanks, stainless steel and plastic/poly, you may find this article helpful. In the following sections we will outline the basic pros and cons of each tank material to provide a comprehensive evaluation for you to rely on.
4 Facts Revealed About Stainless Steel and Poly Storage Tanks
- Durability: It is generally assumed that metals are stronger than plastics. Because stainless steel is one of the most durable metals we use on a regular basis, people tend to assume that a stainless steel tank will outperform a poly tank. However, poly tanks are fabricated in ways that make them competitive with steel in terms of strength. The high flexibility of plastic allows it to be molded into many different shapes without compromising its integrity. While stainless steel resists corrosion in most environments, it cannot withstand highly concentrated acids the way plastics can. If you plan to store harsh chemicals, poly tanks may be a safer choice.
- Set Up: Stainless steel tanks have great aesthetic appeal at the price of low maneuverability. The weight of stainless steel tanks limits the user’s ability to relocate them after they are initially set in place. If you require greater flexibility when it comes to the location of your tanks then poly tanks may be preferable. Poly storage tanks are durable, lightweight, and easy to move around.
- Shipping Costs: The lower weight of poly storage tanks correlates with lower shipping costs than those of heavier stainless steel tanks.
- Varieties: Poly storage tanks are available in a wide variety of constructions, and color combinations. These tanks are made of corrosion proof, chemically resistant materials such as polypropylene, PVC, HDPE, CPVC, PVDF, and HTPP. Poly tanks are ideal for storage capacities below 6,500 gallons. Stainless steel tank is available in a variety of grades and finishes for improved strength and corrosion resistance. Stainless steel tanks can reach capacities exceeding 30,000 gallons.
Given the information listed above we hope you will feel confident in making an educated decision on the type of tank you would like to invest in. You can always consult with a manufacturer or distributor to get personal expert recommendations.
