Double-sided Rib-Reinforced Water Tank

Double-Sided Rib-Reinforced Water Tank

Key Features

Product Advantages

Ultra-High Structural Rigidity
The double-sided arc-rib structure significantly increases panel stiffness, providing more than three times the rigidity of conventional large modular panels.

Improved Pressure Distribution
The continuous corrugated rib design effectively disperses internal water pressure, reducing stress concentration and improving structural durability.

Reduced Internal Reinforcement
The advanced load-transfer design allows the tank to minimize or eliminate internal tie-rods, simplifying the internal structure.

Easy Cleaning and Maintenance
The simplified interior design provides more space for inspection and maintenance, improving cleaning efficiency and operational safety.

No Dead Corners or Water Accumulation
The innovative convex roof and bottom panels prevent water stagnation and eliminate cleaning blind spots.

Extended Service Life
The reinforced structure improves overall tank stability and durability, ensuring reliable long-term water storage.

Technical Highlights

Why Is It Called Double-Sided Rib-Reinforced?

The panel is designed with a bidirectional curved rib (corrugated) structure on both its inner and outer surfaces — hence the name “double-sided rib-reinforced.”

These ribs consist of smoothly connected curved grooves and ridges arranged alternately along the panel length, forming a continuous structural pattern. The rib height typically ranges from 30–90 mm (commonly 55 mm), creating a three-dimensional reinforcement profile.

This engineering design significantly enhances panel rigidity and resistance to deformation. It allows the structure to better withstand concentrated loads, absorb impact forces, and evenly distribute stress throughout the tank system.

As a result, the water tank achieves improved structural stability, longer service life, and higher reliability in demanding applications.

Compared to conventional flat or single-rib panels, this design provides superior stiffness without significantly increasing material usage.

Engineering Validation & Performance Advantage

Base Frame

The double-sided curved rib panel structure is known for its excellent structural rigidity, which can be validated through topology optimization using advanced engineering software such as OptiStruct.

This type of structure has been widely adopted across various industries. Conventionally, double-sided rib panels are manufactured using cold-forming processes such as rolling or pressing.

At Leaqua, our double-sided curved rib panels are developed through comprehensive engineering processes, including computer modeling, structural force analysis, and finite element analysis (FEA).

Compared to traditional flat panels, our one-piece molded and stretched panels achieve more than 5 times improvement in load-bearing performance, delivering significantly enhanced strength and reliability.
