FAQs | GSC Tank


The answer may be as simple as a single material recommendation or there may be several materials that may be considered for many liquid or chemical storage requiremenst. We can provide input for comparison that will include initial cost (including tank cost and shipping cost), installation considerations, long term maintenance requirements and expected tank life. GSC Tanks is committed to ensure our customers have the best tank for their storage requirement.

Polyethylene tanks are more affordable than fiberglass, stainless steel, and aluminum tanks. They are the best choice for storing liquids and flammable products. These tanks are light weighted, chemical resistant and durable in nature. Polyethylene tanks will not be affected by sunlight as these are molded with ultra-violate inhibitors. As the tanks are transparent you can actually see the level of liquid through the walls.

Polyethylene tanks are chemical resistant and long lasting in nature. You can store most agricultural and industrial chemicals, high purity chemicals, most types of bio-diesel, various food products, and potable water. You can come across a few limitations, like solvents, gasoline, and surfactants used in different industrial detergents. Please contact us for more information.

Our standard tanks carry a full 2-year warranty and our heavy-duty tanks carry a 4-year full warranty. These warranties do not apply to special applications, such as sodium hypochlorite & bio-diesel.

Yes, all our above ground tanks are API Tested and Certified.

GSC Tanks are designed for burial but standard above ground tanks are not for burial. If you want you can build a vault and install your above tank inside it.

For a full bottom support, you need to ensure that the area is smooth enough to install the tank. A well-constructed concrete pad, capable of supporting contents of the tank is better than any other supports. Other materials like pea gravel or packed sand, flat blacktop or contained have been used successfully.

A regular inspection is always needed. An annual test is required which includes inspecting the tank wall for small stress cracks or damage caused from stresses of loading from piping or valves, checking all fittings to avoid leakage, mechanical wear from mixers or exposed edges where the tank is hanging. You may find liquid but maybe it is not from the tank. Generally, vertical tanks have a convex that pops up in the center. If condensation forms, it tends to move towards the bottom, and underneath the tank. If the tank is filled the bottom flattens out and moisture come out it which seems to be a leakage problem.

Keeping in mind that liquids expand when frozen. GSC Tanks make polyethylene formulated tanks for low-temperature impact resistance.

Generally, for storing hot liquids the common industrial recommendation is not to exceed 140 to 150 degrees. It is found that at 120-degree polyethylene tanks start losing sidewall strength. If you are exceeding 120 degrees you may add a fiberglass reinforcing on the sidewalls which can handle temperature up to 175 degrees.

Life expectancy totally depends upon your application. There are various things which can affect the lifespan of your tank like the chemical being stored, what you are using the tank for and also the temperature. You have to be concerned about the installation process of your tank. The tank needs to be installed on a flat and clean surface. If you install heavy equipment directly on the tank it may cause the tank to fail prematurely. A regular inspection is needed to increase the lifespan of your tank.
