What is FRP Tank?
FRP Storage Tank is currently the leading industry standard tank on the market, due to its lightweight and strong fiberglass design, the FRP tank provides safe storage without the risk of corrosion or bacterial contamination.
With ideal design characteristics, shape performance, and ease of maintenance, compared with steel, FRP (fiberglass reinforced plastic) has high corrosion resistance and a specific gravity of 1.5 to 1.9, much lower than 7.8 for steel. However, its mechanical strength is higher than steel. It is also characterized by a low coefficient of thermal expansion and thermal insulation of the facades. FRP tank is widely used in many fields.
Advantages of Fibreglass Storage Tanks
100% Watertight
Fibreglass (FRP) tanks are manufactured as a completely sealed unit. Penetrations through the walls are made in the factory with compatible materials. There are no joints in the unit which are required to be sealed on site. This makes the tanks 100% watertight.
Being watertight has two distinct advantages. First, it prevents the ingress of other fluids and gases into the tank. There by avoiding contamination or dilution of the stored product. Second, it prevents the contamination of the surrounding area with chemicals leaking out of the storage tank.
Resistance to Chemical Attack
Fibreglass (FRP) was recognised early in its development as having a high resistance to chemical attack. GRP Tank Solutions carefully selects the most appropriate resin system for the required applications to ensure it meets the asset owners expectations.
Low Maintenance
Due to the smoothness of the glass resin interior surface of the Fibreglass (FRP) units, particles have difficulty adhering to the sides. The smooth walls of the Fibreglass (FRP) station mean the time taken and frequency of washing down the tanks and build-up of product on the tank walls is significantly reduced. Thereby reducing the operator’s maintenance costs and equipment downtime.
Ease of modifications during the life of the tank
During the life of any tank minor modifications are generally required to the external fixtures in the tank. For example, the addition of extra brackets etc. These can easily be added to the station by utilising Fibreglass (FRP) brackets or mounting plates which are “glassed” onto the internal walls at the required location. It is not necessary to drill through the wall for anchorage. As such the overall structural integrity and water tightness of the structure is not compromised.
Abrasion Resistance
The Fibreglass (FRP) tanks are manufactured to have high surface abrasion resistance. This is achieved by forming a layer of pure resin material at the surface which is not only smooth, thereby reducing friction, but also has high strength.
Raw Material Selection
The manufacturing process of FRP tanks begins with the careful selection of high-quality materials.
These typically include fiberglass reinforcements and a thermosetting resin.
Fiberglass reinforcements provide the tanks with strength and rigidity, while the thermosetting resin acts as a binder, ensuring excellent corrosion resistance.
Mold Preparation
Preparing the mold is a crucial step in manufacturing FRP tanks.
The mold determines the tank's shape and dimensions and is typically made from fiberglass, steel, or aluminum.
Meticulous cleaning and treatment of the mold ensure proper release and a smooth surface finish.
Layering and Resin Application
Layering is a critical step in FRP tank manufacturing.
Pre-cut fiberglass reinforcements, shaped according to requirements, are carefully positioned within the mold.
The number and arrangement of these layers depend on the tank's intended use and desired strength. After layering, the thermosetting resin is applied to saturate the fiberglass fully and ensure a strong bond.
Curing Process
Following the resin application, the curing process begins.
The tank is subjected to heat and pressure, allowing the resin to harden and bond with the fiberglass reinforcements.
Curing is vital for achieving the desired strength and durability of the final product. The duration of the curing process varies based on the tank’s size and complexity.
Trimming and Finishing
Once the tank has cured, it is carefully removed from the mold.
Any excess fiberglass is trimmed, and the surface is prepared for finishing touches.
This may involve sanding, buffing, or applying a protective gel coat to enhance appearance and UV resistance.

Steps to Maintain FRP Tanks
Step 1: Visually examine the tank
Inspect the tank visually at first. During this step, both interior and exterior surfaces are meticulously inspected. It is done for the purpose of discovering any damage, corrosion, or any other abnormalities that could affect the FRP tanks cleansing process. This phase is essential because it identifies areas that may require special attention or repairs prior to cleansing.
While examining the interior of the FRP tanks, remove any access coverings or manholes to obtain a clear view. Examine the walls, floor, and ceiling of the tank for fractures in the FRP layers. It is necessary to check the joints and connections for the leakage. During the interior examination, it is important to determine whether any extraneous residue is accumulated.
The exterior examination must include roof, bottom or any fixtures that are affixed. Examine metal components of the FRP chemical storage tanks, such as support structures, connectors, and fasteners, for corrosion or rust. Pay close attention to areas of the tank that are in contact with the ground or other structures. It is so because they may be more prone to damage or corrosion.
Step 2: Inspect for leaks
Before beginning the cleansing procedure, it is essential to inspect the FRP tanks for leakage to ensure its structural integrity. This phase involves pressurizing or filling the reservoir with water in order to inspect for leaks. Resolve the leaks prior to cleansing by conducting a leak test.
Before conducting the leak test, ensure that the reservoir is emptied and close all the access points like valves. Mark the locations of any detected breaches and resolve the problems before proceeding with the cleansing.
In lieu of pressurizing the FRP water tanks, a water fill test can be performed by filling the tank with water. Internally and externally inspect all areas of the tank for signs of water leakage, such as leaking, collecting, or damp patches. Depending on the nature and severity of the leakage, restorations may consist of repairing damaged areas, replacing defective components, or applying appropriate sealants or coatings.
Step 3: Cleaning
A series of procedures are required to ensure the complete removal of residues and deposits. Empty the tank's contents according to the correct procedures. Ensure that all valves and outlets are closed or disconnected to prevent spillage and leakage during cleansing. Once the tank has been emptied, it should be flushed with water to remove any remaining debris, sediment, or liquids.
Choose a cleansing solution based on the type of contaminants or residues present in the FRP chemical storage tanks. Heavy deposits or residues may necessitate additional cleansing efforts. Utilize specialized equipment such as stiff-bristled scouring brushes or high-pressure water nozzles, to effectively remove obstinate deposits. Ensure that all cleaning solutions and residues or deposits are completely flushed out by directing the water flow across all interior surfaces of the FRP tanks.
Step 4: Check for the FRP tank's support
It is essential to inspect the tank's supports, anchors, and structural components to ensure tank's durability. This phase involves inspecting these components for any signs of damage, deterioration, or vulnerabilities that could compromise the structural integrity of the FRP tanks.
Examine the item for any obvious indications of damage, such as warping, splitting, corrosion, or missing parts. Pay close attention to any indicators of deterioration, such as excessive corrosion, pitting, or material degradation. By addressing any issues discovered during the inspection, the stability, safety, and longevity of the FRP tanks can be maintained. It ensures proper operation and minimizes the risk of catastrophic failures.
Step 5: Interior of the FRP tanks
It is essential to monitor the interior environment of the FRP tanks. It comprises monitoring factors such as humidity, temperature and ventilation to keep the tank in the optimal condition.
Assess the humidity levels within the tank, especially for tanks that may contain moisture-sensitive materials. Regularly monitor the temperature inside the tank to ensure that it remains within the recommended range for the liquids or substances being stored. Utilize strategically located temperature sensors or indicators within the FRP chemical storage tanks to accurately monitor the temperature. Ensure that the tanks have adequate ventilation to promote air circulation and prevent the accumulation of potentially hazardous gasses or vapors.
