What is Sectional Modular Circular Steel Water Tank?
Modular Steel Tank Design
Height Range: 1–5 meters
Diameter: 4 meters
Material Options: Hot-Dip Galvanized Steel / Stainless Steel
Our sectional circular steel water tank is a modular, corrosion-resistant solution designed for versatile applications such as irrigation, aquaculture, livestock farming, and industrial water storage. With a standard 4-meter diameter and customizable height from 1 to 5 meters, this tank offers flexible storage capacity tailored to your project needs.
Key Features:
Durable Material Options: Choose between hot-dip galvanized steel for cost-effectiveness and strong corrosion resistance, or stainless steel for premium durability and longevity.
Modular Panel Design: Pre-fabricated pressed steel panels allow for quick on-site assembly, transportation efficiency, and easy maintenance.
Reinforced Structure: Each panel is engineered with an embossed “X” rib design to enhance structural integrity under high water pressure.
Corrosion Resistance: Both stainless and galvanized steel options offer excellent performance in harsh environments.
Versatile Applications: Ideal for agriculture, aquaculture tanks, rainwater harvesting, and industrial water storage systems.
Advantages:
No need PVC liner like corrugated steel water tank, we use EPDM rubber to connect between panels.
Inlet/outlet flanges and overflow fittings customized according to your requirements.
Roof or open-top design for your customized requirement.
Easy to install and better anti-leaking design.
Design and Manufacture of Sectional Modular Circular Steel Water Tank: Featuring Bottom Plate, Side Panels, and Optional Top Cover
The round modular sectional steel water tank is designed to provide flexible water storage solutions, suitable for a variety of applications, from agricultural irrigation to industrial uses. The tank is primarily composed of the following key components:
Bottom Plate: A durable, reinforced steel base that provides stability and ensures the tank can withstand the weight of the stored water.
Side Panels: Constructed from high-quality steel, these panels are assembled in a modular fashion, ensuring easy transport and assembly. They are designed to resist corrosion, ensuring long-term durability.
Top Cover (Optional): The tank’s design includes an optional top cover, which can be added for increased protection and water containment. The cover helps to prevent contamination and reduces water evaporation. For specific applications, such as rainwater harvesting, the top cover can be optional, depending on environmental and functional needs.
This design flexibility allows the tank to be customized based on user requirements, whether a covered or open-top tank is needed. It is ideal for both indoor and outdoor environments, offering a versatile and cost-effective solution for water storage.
