Auxiliary (Angle) Iron : Overview
Auxiliary angle iron—also known as support angle iron or structural angle bracket—is a critical component in the assembly of sectional panel water tanks (also called modular or bolted panel tanks), this L-shaped metal profile provides essential structural reinforcement at corners, edges, and internal junctions of the tank. the auxiliary angle iron ensures rigidity, alignment, and load-bearing integrity during and after installation.
Key Functions of Auxiliary Angle Iron
1-Corner Reinforcement
Installed vertically at all four internal and external corners, angle iron prevents panel deformation under hydrostatic pressure and maintains precise 90° angles.
2-Horizontal Bracing Support
Used with tie rods or perimeter beams to resist outward bulging, especially in taller tanks (>2m).
3-Foundation Alignment & Leveling
The base angle iron helps anchor the bottom tank panels evenly to the concrete slab, ensuring a leak-proof seal.
4-Simplified Assembly
Pre-drilled holes in the angle iron align with panel flanges, enabling fast, tool-efficient bolting without on-site welding.
5-Load Distribution
Transfers the weight of stored water evenly across the tank structure and foundation, reducing stress concentration.
Installation Considerations
Proper installation is crucial:
Level Foundation: The bottom angle ring must be perfectly level on the foundation to ensure the entire tank structure is plumb.
Correct Bolting: Use the specified grade of bolts, nuts, and washers, torqued to the recommended specification.
Sealing: In some designs, sealant is applied between connections for an additional barrier.
Conclusion
In summary, auxiliary angle iron is the unsung hero of sectional panel water tank construction. It is a critical, cost-effective component that ensures the tank’s structural stability, longevity, and safe operation by providing a robust framework for the containment panels. When procuring a tank, specify angle iron that matches or exceeds the corrosion protection and material quality of the main panels for a uniformly durable asset.
