1.Water Tank Sectional Panel : Overview

A water tank sectional panel is the fundamental building block of a modular, bolted water tank. These tanks are assembled on-site from multiple prefabricated panels, offering a flexible, durable, and widely used solution for water storage in residential, commercial, industrial, and municipal applications.
Unlike one-piece tanks, sectional tanks are constructed by connecting strong, factory-made panels using bolts, nuts, and specialized seals. This modular design allows for easy transportation, installation, and scalability.

2.Main Types of Sectional Panels

1）Material
The choice of material depends on the application, budget, and the liquid to be stored. The main types we supply are:
✅ GRP (Glass Fiber Reinforced Plastic): Lightweight and highly corrosion-resistant. Ideal for aggressive chemicals or environments where metal is unsuitable.
✅ Hot-Dip Galvanized Steel: A common and cost-effective choice for potable water. Steel panels are coated in zinc for excellent corrosion resistance and strength.
✅ Stainless Steel: Used for high-hygiene applications or for storing slightly corrosive liquids. Common grades are 304 and 316.
2）Standard Sizes
Standard panel sizes include 1m x 1m, 1m x 1.5m, 1m x 0.5m, and 0.5m x 0.5m. The 1m x 1m size is the most commonly used. Since panels have fixed dimensions, the final tank capacity will be an integer multiple of a single panel's area.

3.Connection Methods

Bolted Connection: The standard method. Panels are joined with bolts, nuts, and gaskets. This method is used for GRP, galvanized steel, and stainless steel tanks.
Welded Connection: An option for stainless steel panels. Welding can lower the material cost but requires skilled on-site labor for assembly.
Conclusion
Sectional water tank panels represent the gold standard in modern water storage solutions — combining strength, flexibility, and longevity in a single, engineered system. Whether made from GRP, hot-dip galvanized steel, stainless steel (304/316), or GRP, these modular panels offer unmatched advantages for projects of any scale. For more specific，Contact today!
