Compartment Design (Partitioned Tank)
The GRP sectional water tank can be designed with internal partition walls to create multiple compartments within one tank.
This design allows:
1.Independent water storage zones
2.Easy maintenance without stopping the whole water supply
3.Improved water hygiene management
4.Flexible water management for large systems
Each compartment can be equipped with separate inlet, outlet, overflow, and drain connections if required.
GRP Sectional Water Tank Panels
To meet diverse structural and project requirements, our fiberglass water tanks utilize two proven panel designs: convex panels and diamond-shaped panels.
All panels are made of high-quality fiberglass reinforced plastic (GRP) material and manufactured using a hot-pressing process, ensuring excellent strength, corrosion resistance, and a long service life.
Diamond Square GRP Water Tank Panel
The diamond square panel features a geometric embossed pattern that distributes water pressure evenly while offering a clean and professional appearance.
Key Advantages:
Excellent structural stability
Standardized panel size for flexible installation
Neat appearance, ideal for indoor or visible installations
Applications:
Municipal water supply projects
Commercial and residential buildings
Overseas infrastructure and standardized engineering projects
Convex GRP Water Tank Panel
The convex panel design enhances panel rigidity through a raised surface structure, improving overall load-bearing performance and long-term stability
Key Advantages:
Increased panel strength and stiffness
Even pressure distribution
Suitable for large-capacity sectional water tanks
Low deformation risk and long service life
Applications:
Domestic water storage systems
Firefighting water tanks
Industrial water storage projects

Packaging and Transportation
Our GRP (FRP) water tanks feature a modular panel design, ideal for overseas shipping. All GRP panels are securely framed with steel frames to prevent damage during long-distance transport. Accessories such as bolts, tie rods, flanges, and rubber seals are individually packaged in sturdy plywood crates. This compact packaging maximizes container capacity, thereby reducing international shipping costs.
FAQ for FRP / GRP Water Tank
An FRP (Fiber Reinforced Plastic), also known as GRP (Glass Reinforced Plastic), water tank is a modular or sectional water storage tank made of fiberglass-reinforced resin panels.
It is widely used for potable water storage, fire fighting systems, industrial water, and municipal projects due to its high strength, corrosion resistance, and long service life.
GRP water tanks offer several advantages:
Corrosion-resistant (no rust, suitable for coastal or chemical environments)
Lightweight but high strength
Modular design, easy transportation and on-site installation
Long service life (20–30 years with proper maintenance)
Low maintenance cost
Food-grade materials available for potable water
Compared with carbon steel or concrete tanks, GRP tanks are more cost-effective over the long term.
Yes. Our GRP water tanks are manufactured using food-grade resin and panels that comply with international drinking water standards.
They are safe for potable water storage and widely used in:
Residential buildings
Hotels & hospitals
