What is grp water tank? GRP water tank (also known as Fiberglass Reinforced Water Tank) is also called SMC storage water tank, FRP water storage tank, SMC panel tanks, FRP panel tank, GRP panel tank, GRP sectional water tank, GRP panel tank etc.

It consists mainly of fiberglass and resin called Sheet Molding Compound” -- a fiber-reinforced material that consists of a thermosetting resin glass fiber. It is hydraulically hot pressed into panels of varying sizes and thicknesses depending on the customer's needs. We provide regular grp sectional water tanks, such as 1m3 smc water tank. Normal grp water tanks panels is 1m*1m.

These panels are then used to assemble the panel water tank by connecting them to each other via the steel skeleton and rubber gaskets in between each panel.

We supply grp water panel tanks depending on the customer’s needs.

We provide blue frp water panel tanks used in buildings.

We provide frp sectional water panel tanks used for storing rainwater.

We offer frp water panel tanks used in buildings.

There are common nine kinds of accessories about FRP&GRP water tank:


Sealing taps



The GRP water tank is built completely with internally flanged base and externally flanged side walls. This tank varies from light to heavy duty. It is suitable for water storage having a stainless steel platform at the bottom where the water will settle down.


As designed based on a standard tanks requirement, GRP water tank is sealed with galvanised bolts and nuts. It uses galvanised bolts and nuts to BS 729 with stainless steel grade 316 bolts under water.


Having a depth of a minimum of 1.5 meters, GRP storage tank has a ladder both inside and out. This is applicable on tanks not on raised platform, but if it is so, ladders will be a bit lower on its height. Safety cages will be installed in accordance to BS4211 1994 on external ladders on tanks with a minimum height of 2 meters.




Inner support rod

The inner support rod of the tank as provided for additional rigidity of the tank performance, should be checked against corrosion to avoid malfunction and contamination. If it corrodes, rectification is recommended.

Steel C-channel base

The base of this GRP water tank is provided with steel c-channel for durability in either light or heavy duty purposes. This adds the provision that the tank could be laid directly on a concrete plinth on a trowelled finish, brushed clean, and free from any protuberances.  The surface should be flat.

Drawing bar plate

Tank is provided with drawing bar plate for the tensile force of the tank to resist when it stored. To a desired capacity, this will allow the water inside to maximize avoiding the tank from having any deformation.

Drawing bar plate

Inner drawing bar

With almost the same purpose to the external drawing bar plate, the GRP water tank inner drawing bar adds the purpose of tensile counteract of both the flow of the stored water inside and the stretch of the enclosure tank material.


The tank is provided with plugs to prevent leaks and stop seeping of water on any holes and  joints. It is abrasive resistant and is compatible with any waterproofing substances.It will locate on the four corners on top and on the bottom.

Glass cement

Glass cement has been used on setting mortar on plugs during installation or on any leaks or  cracks during repair. when we finish the installation by screws. Glass cement is very neccessory. if build a 400cubic meter. it will need 40bottles cements.

Excellent UV and weather-resistant characteristics; Corrosion and rust resistant

This means that whether they are placed inside or outside, the GRP water tank will remain functional and reliable despite the hot sun, pouring rains, or even acid rain.

High strength and Durability

This feature ensures you that the panels and structure itself is sturdy and tough enough to withstand the normal wear and tear of normal everyday use.

Easy installation by plumbers and general technicians with the help of conventional tools

This is also thanks to the GRP panel water tank’s simple design. It doesn’t require specialized tools or assistance which are often costly and time-consuming.

Excellent Hygienic, good water quality

This means that you can safely store drinking water without fear bacteria or chemicals being released by the panels themselves because the panels are non-toxic and they prevent bacteria increasing.

High seismic tolerances; Does not deform or dent

This is another proof of the GRP water panel tank’s durability and strength. This is an especially relevant piece of information for you readers who live in places where earthquakes and tremors are a constant threat.


This says that the GRP water tank, despite being constructed from separate panels, have been designed and made to fit each other so well that no leaks occur.

Low thermal conductivity and excellent thermal insulation

This means that your GRP water tank won’t conduct heat very much. This has the effect of keeping warm water warm and cool water cool-- depending on what temperature water you placed in the tank.

Easy cleaning and maintenance. Convenient to manage

The GRP water panel tank is mostly hollow on the inside, apart from the metal pipes that make up its skeleton. This simplicity in design means that the tank is easy to clean and maintain.

Easy to assemble in any size

Because the tank is a GRP panel type water tank, you can basically build up your tank to any size on site. This saves you both time and money that would have gone to buying a new fixed-sized tank.

Easy to dismantle and shift in case of change

Again, because of the simple design and structure, the GRP water tank can be disassembled just as quickly as it was assembled if you ever need to move your home or business.

Easy to increase or decrease the size

Finally, because the tank is made up mostly of panels, you’ll find it really easy to increase or decrease its capacity and size by simple adding or subtracting panels from it.


Since the GRP water tank is so modular and customizable, it naturally has lots of possible applications.

Here are some of the key applications for the GRP water tank:

For your residential or commercial drinking water storage:

Homes and businesses need drinking water for their family members or occupants. Grp water tank sizes and capacity can be made to fit into any of these places so this one’s a no-brainer.

For collecting and storing rainwater:

Dryer places with low water supply or rainfall will find that the ability to store large amounts of water during those rainy times can be a godsend. Can also be used if you just want to live off the grid.

For agriculture water tank:

As climate change, there may be a long and unpredictable dry season, many growers are turning to water storage tanks to help offset these droughts.

For storing hazardous materials or waste:

This is more for businesses and enterprises that produce hazardous wastes as a by-product.

Libraries, schools, colleges, universities, hospitals, construction sites, and industrial buildings:

Important to these places that have fire hazards (factories for chemicals and fuel, paper storage, etc) or because their main business is requires large amounts of water (concrete mixing for construction sites, water amusement parks, swimming pools, golf courses, car washers, farming and livestock, etc.).
