What is GRP water tanks?
Description
GRP water tank ( Glassfiber Reinforced Plastic Water Tank) is also called “SMC storage water tank”, It is a good way to store water, It is installed by SMC panels, bolts & nuts, Seal components, steel instruction parts, suitable pipes. It is easy and quick to installation. The GRP panels are connected by the bolts&nuts, steel support rod, sealing rubber strips, basic channel steel, lacing wire, lacing wire plates, ladders, manhole cover, flanges, etc. More and more traditional water tanks are being replaced by GRP tanks.
Sectional GRP panels size are: 1000mm*1000mm, 1000mm*500mm, 500mm*500m, The thickness of the GRP panels vary depending on the height of the tank, the higher the tank, the thicker the bottom row panels will be. Customized capacity accepted from 1m³ – 1000 m³

SMC = Sheet Moulding Compound
FRP = fiber-reinforced plastics
GRP = glass-reinforced plastic
What is GRP panels?
GRP panels
GRP panels means the panels made by material of fiberglass reinforced plastic, it consist mainly fiberglass and resin, it is hydraulically hot pressed into panels of varying size. The manufacture process are method of SMC mould pressing technology. The panels can be used to assemble the GRP water tanks, connected by the bolts&nuts, steel support rod and sealing taps etc.
GRP panel size and thickness?
Sectional GRP panels size are: 1000mm*1000mm, 1000mm*500mm, 500mm*500m,
The thickness of the GRP panels vary depending on the height of the tank, the higher the tank, the thicker the bottom row panels will be.
The thickness of the GRP panels is related to the dimensions of the water tank, different dimension with different height, It mainly depending on the height of the tank, the higher the tank, the thicker the bottom row panels will be.
As we know, the stainless steel water tank thickness representation unit is mm, but GRP water tank always us # or Kg to representation the thickness, when we inquiry the price, we can ask the GRP water tank panel thickness by # or kg.
Performance of GRP panel?

- Tensile strength,Mpa:≥60
- Bending strength,Mpa:≥100
- Bending modulus,Gpa:≥7.0
- Pap hardness:≥60
- Bibulous rate,% :≥60
- Glass fiber content,% :≥25
How To Produce GRP water tank?
The manufacture process of GRP water tank are method of SMC mould pressing technology,The main component of water tanks are GRP panels, The panels made by material of fiberglass reinforced plastic, it consist mainly fiberglass and resin, it is hydraulically hot pressed into panels of varying size. The panels are assemble by bolts & nuts, Seal components, steel instruction parts, suitable pipes etc.
What is difference between GRP and FRP?
FRP means fiber-reinforced plastics, it’s a term typically used stateside here in North America. GRP is a term that means the same thing. But it’s generally used over in Europe and Asia and stands for glass-reinforced plastic.
Application of GRP water tank?
The water tank has been widely used in:
- Residential buildings
- Hotels & office buildings
- R&D building, schools, malls, restaurants
- Hospitals and food processing plants
- other public facilities as well as places with high requirements for water quality.

6 advantages of GRP water tank
Glass Reinforced Plastics (GRP) This material is ideal for the manufacturing of water storage tanks due to its unique set of properties. Some of the benefits to choosing FRP water tanks include:
- Leak free
- Rapid construction (installation) using modular design
- Very lightweight
- Flexible in shape and size, and can be dismantled/modified after GRP tank installation
- Maintains excellent water quality throughout the life of the tank
- Can be easily installed in difficult sites with limited access/height restrictions

Installation of GRP water tank?
We supply installation guide, Installation and training service to clients,
If need us to support installation work at customer’s side,we also can provide on customer’s requirement.
Installation preparation work: before installation, please do construct of concrete basic foundation, provide electric power supply, check needed water.
Maintenance of GRP water tank?
Maintenance service is applied when customer cannot solve problem by themselves.
Avoid fire near to water tank. Please protect water tanks when welding steel channels, Avoid pollutant enter into water tank. In order to convenient maintenance, please leave some space between water tank and wall. Please do not beat water tank body by any tools or something hard. New water tank must be clean two times before using.
Are fiberglass water tanks safe for drinking water?
Yes, it is safe for drinking water. The raw material used in the FRP water tank is “food-grade resin”, and all the accessories in the water tank use material stainless steel 304, So it is completely no problem to install drinking water.
