Welcome to Hengshui City Yike Composite Materials Co., Ltd., a trusted manufacturer since 2009 with an annual export value of US$1.5–2.5 million. Our Modular FRP GRP Rectangular Water Tank for Drinking Water is designed to deliver superior corrosion resistance, structural integrity, and long service life. Whether you need a reliable underground chemical storage solution or a potable water reservoir, this SMC panel tank offers modular flexibility and easy on-site assembly. With shipments from Tianjin and Shanghai ports to markets across North America, Europe, Southeast Asia, Africa, and Oceania, our product meets global standards for hygiene and durability.
This tank is engineered using advanced Sheet Molding Compound (SMC) technology, combining fiberglass reinforced plastic (FRP) and glass-reinforced plastic (GRP) to create a lightweight yet robust structure. The rectangular design optimizes space utilization, making it ideal for both underground and above-ground installations. Each panel is precision-molded to ensure a perfect fit, and the modular system allows for capacity expansion without structural compromise. Below, we detail the key features and technical specifications that set our tank apart.
- Corrosion Resistance: The FRP/GRP material inherently resists rust, chemical attack, and UV degradation, making it suitable for drinking water, rainwater, and a wide range of chemicals.
- Modular & Expandable: Panels can be added or removed to adjust capacity from 1,000 liters to over 100,000 liters, offering flexibility for future needs.
- High Strength-to-Weight Ratio: SMC panels provide high mechanical strength while remaining lightweight, reducing transportation and installation costs.
- Hygienic & Safe: The inner surface is smooth and non-toxic, preventing bacterial growth and complying with food-grade water storage standards.
- Easy Installation: Bolted panel assembly requires no heavy equipment, and the tank can be installed in confined spaces or underground.
- Seismic & Leak-Proof: Silicone gaskets between panels ensure a watertight seal, and the flexible structure can withstand ground movement.

The modular design allows for customized configurations. For example, a tank with dimensions 4m × 3m × 2m (24,000 liters) can be assembled from standard panels in just 2–3 days by a small crew. The bolted connections eliminate the need for welding, reducing fire risk and simplifying maintenance. Additionally, the tank can be equipped with a corrosion-resistant lining for aggressive chemical storage, making it suitable for wastewater treatment, industrial processing, and agricultural irrigation.
Our Yike Composite team has over 15 years of experience in composite tank manufacturing. We have exported to more than 30 countries, including the United States, Germany, Australia, and Saudi Arabia. Our production facility in Hengshui, Hebei, utilizes advanced compression molding machines to ensure consistent panel quality. Each tank is factory-tested for watertightness before shipment. We offer a 10-year warranty on panel integrity and a 5-year warranty on seals, reflecting our confidence in product durability.
Frequently Asked Questions
-
Q: Can this tank be used for drinking water?
A: Yes, the inner surface is made from food-grade resin and does not release harmful substances. It meets the requirements for potable water storage, and we can provide third-party test reports upon request. -
Q: How is the tank installed underground?
A: The tank is assembled on-site in a prepared excavation. A concrete base or compacted sand layer is recommended. The lightweight panels make it easy to handle. Backfilling must be done gradually with proper compaction. -
Q: What is the maximum capacity available?
A: The modular system can be configured up to 100,000 liters or more. For larger capacities, we can design reinforced panels and additional support structures. -
Q: Are replacement panels available?
A: Yes, individual panels and gaskets can be ordered separately. This makes maintenance and capacity expansion simple and cost-effective. -
Q: What chemicals can be stored?
A: The tank is resistant to many acids, alkalis, and salts. For specific chemicals, we recommend providing a list so we can confirm compatibility and suggest appropriate resin types. -
Q: How long does the assembly take?
A: For a typical 10,000-liter tank, a team of 2–3 workers can complete assembly in 1–2 days. Larger tanks may require 3–5 days. Detailed installation manuals and video guides are provided. -
Q: What is the warranty period?
A: We offer a 10-year warranty against manufacturing defects in panels and a 5-year warranty on rubber gaskets. The warranty covers material and workmanship under normal use. -
Q: Do you offer custom colors or branding?
A: Yes, we can produce panels in any standard RAL color, and we can also add your company logo or other markings on the panels during molding.
