Reliable Water Storage Solution from a Trusted Manufacturer
As a professional manufacturer with over a decade of experience, Hengshui City Yike Composite Materials Co., Ltd. is proud to present our Modular FRP/GRP Rectangular Water Storage Tank. Engineered for exceptional corrosion resistance, this tank is ideal for both potable water storage and underground chemical containment. Our panels are produced using advanced SMC (Sheet Molding Compound) technology, ensuring consistent quality and long-term durability. Whether you need a small tank for residential use or a large-scale industrial reservoir, our modular design allows endless customization to fit your specific site requirements.
Key Features & Technical Advantages
- Corrosion-Resistant Construction – The FRP/GRP material is inherently resistant to rust, chemicals, and UV degradation, making it suitable for harsh environments and long underground service life.
- Modular Panel System – Each tank is assembled from pre-fabricated panels using high-strength bolts and a sealed gasket system. This simplifies transportation and on-site installation, even in confined spaces.
- Safe for Drinking Water – Our tanks are lined with food-grade resin and meet international standards for potable water storage. No toxic leachates or metallic taste.
- Underground & Above-Ground Use – Reinforced structural ribs and optional external coatings allow the tank to withstand soil pressure and groundwater when buried, while also being perfectly functional when placed on a foundation.
- Low Maintenance – Unlike steel or concrete tanks, FRP/GRP does not require frequent repainting or anti-corrosion treatment. Smooth inner surfaces reduce biofilm buildup and simplify cleaning.
- Customizable Dimensions & Configurations – We can produce tanks from a few hundred liters to thousands of cubic meters, with options for manholes, flanged connections, internal baffles, and thermal insulation.

Why Choose Our Modular FRP/GRP Tank?
- Fast Installation – Modular design reduces installation time by up to 50% compared to monolithic concrete or welded steel tanks.
- Lightweight – FRP panels are ~1/4 the weight of steel, lowering transportation costs and allowing installation without heavy cranes.
- Chemical Resistance – For underground chemical storage, our tanks can be formulated with special resins to resist acids, alkalis, and solvents.
- Leak-Proof Joints – Each seam uses a double-lip EPDM gasket and stainless steel bolts, ensuring zero leakage over decades of service.
- Lifecycle Economy – With a service life of 20+ years and minimal maintenance, the total cost of ownership is significantly lower than conventional tanks.
