Water tank products
Insulation Water Tank
Product Description
The Insulated Water Tank is equipped with an additional thermal insulation layer installed outside the main tank body, effectively minimizing heat loss and maintaining stable internal water temperature under extreme outdoor conditions. This design prevents freezing in cold regions and reduces excessive heat absorption in hot climates. The system is widely applied in drinking water storage, industrial water supply, cleaning systems, and municipal infrastructure projects, especially in areas with significant temperature variations.
Modular assembly
GRP Water Tank Structure
GRP Water Tank System Includes: GRP panels Internal reinforcement Base support structure Bolted connection system Sealing system Inlet/outlet fittings and accessories
High-Strength GRP Panels
Durable, corrosion-resistant panels for long-lasting water storage.
Reinforced Steel Structure
Strong steel support ensures stability and safe load-bearing.
Leak-Proof Sealing System
Reliable sealing design ensures excellent water tightness.
Insulation Water Tankk 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.

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 Insulation 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
