Difference between Fiberglass and Polyethylene Water Tanks: A Comparative Study

While buying industrial storage tanks, we always like to invest in those units that are sturdy, durable, cost-effective and require low maintenance.

Fiberglass and Polyethylene are the two kinds of storage tanks that have become extremely popular for storing liquids, chemicals, and oil.

Engineered for critical applications, both of them are drastically different from each other which we are unaware of. Let’s highlight the main dissimilarities between the two.

1. Manufacturing Process

Fiberglass tanks are handcrafted units and are manufactured in a labor-intensive process. They are produced in bulk quantities through hand lay-up and filament winding processes.

On the other hand, polyethylene water tanks are manufactured using automated processes. They are engineered to perfection by roto-molding or the plastic welding process.

2. Construction

Fiberglass tanks are constructed by reinforcing high-performance glass plastics and resin materials. They are known for their corrosion-free and heat resistant properties. Hence they are a popular choice for storing industrial chemicals.

Polyethylene water tanks are constructed by heating two pieces of polyethylene are joined together through pressure application.

3. Cost

Fiberglass tanks are expensive due to their complex manufacturing process. In addition to that corrosion barriers made of resin contribute to its high price significantly.

Polyethylene water tanks are less expensive because of the lower cost of raw materials and manufacturing process.

4. Maintenance

Fiberglass tanks require more maintenance because of the fact that the tanks develop corrosion over time.

If the corrosion is not dealt on time, leaks will occur resulting in the wastage of the contents. Hence careful maintenance and inspection of the industrial storage tanks are necessary from time to time.

On the other hand, polyethylene water tanks do not require much maintenance and inspection because they offer resistance to corrosion.

These tanks are also manufactured without seams and interior coatings which make them easy to maintain.

Therefore investing in polyethylene tanks will save you lots of money in the longer run! In fact, due to its durability and less maintenance, high-density cross-linked polyethylene storage vessels have become extremely popular.

Hopefully, with all the above-mentioned points, you will be able to distinguish between fiberglass and polyethylene tanks clearly. This will make your purchasing decision simple and effortless.
