What is a GRP water tank?
GRP Water Tank, also called FRP Water Tank, Fiberglass Water Tank, or SMC Panel Water Tank, is a modular sectional water storage solution made from high-quality SMC composite panels. The tank adopts a bolted assembly design with standard panel dimensions of 1×1 m, 1×1.5 m, and 0.5×0.5 m, allowing customized sizes and capacities according to project requirements.
Designed for durability and reliability, GRP sectional water tanks offer superior corrosion resistance, hygienic water storage, lightweight construction, fast installation, and low maintenance costs. They are widely applied in domestic water supply, commercial buildings, industrial water storage, municipal projects, and fire protection systems.
Advantages of GRP Water Tank
High resistance against rust, chemicals and harsh environments.
Suitable for coastal and industrial areas.
Smooth inner surface prevents bacteria growth and contamination.
Suitable for potable water applications.
Bolted panel structure allows easy transportation and installation.
Tank dimensions can be designed according to project requirements.
Durable SMC panels provide reliable performance for decades.
Individual panels can be replaced without dismantling the entire tank.
GRP Water Tank Structure
Our GRP water tank is manufactured from premium SMC roof, side, and bottom panels, reinforced with an internal support system, stainless steel or hot-dip galvanized tie rods, EPDM sealing gaskets, and high-strength bolted connections. The modular sectional design provides superior structural strength, excellent corrosion resistance, leak-proof performance, and quick installation, making it an ideal solution for potable water, fire protection, commercial, and industrial water storage applications.
