Hotel, School, and Hospital Domestic Water Storage Tank Solutions
Key Points Tag :
The galvanized steel water tank is manufactured from Q235A steel, pressed into standardized panels and assembled using bolted connections. Standard panel sizes include:1220 mm × 1220 mm,1000 mm × 1000 mm,1000 mm × 500 mm,500 mm × 500 mm.

Each panel is pre-drilled along the edges, and the joints between panels are sealed with silicone rubber gaskets, ensuring excellent watertight performance.

Hospitals have even stricter requirements for domestic water supply systems. In addition to daily domestic water usage, hospitals require water for medical cleaning, equipment operation, surgical areas, and emergency backup storage. Therefore, the water supply system must operate continuously and reliably 24 hours a day. Some hospitals adopt dual water tank backup systems and intelligent water level control systems to ensure uninterrupted water supply even under emergency conditions, providing safer and more reliable water storage solutions for medical environments.
Advantages of HDG Steel Panel Water Tanks:
- Low Maintenance Requirements
Thanks to the corrosion-resistant zinc coating, HDG water tanks require minimal maintenance. Regular inspections are typically sufficient, helping to reduce long-term maintenance costs and ensuring continued performance over time.
- Exceptional Corrosion Resistance
The zinc coating applied during the hot-dip galvanizing (HDG) process acts as a robust shield, protecting the steel from rust and corrosion. This significantly enhances the longevity of the HDG water tank compared to untreated mild steel, ensuring a longer service life.
- Strength of Steel, Durability of Zinc
HDG water tanks are designed to withstand heavy loads and high pressure. The added layer of zinc provides extra protection, making these tanks ideal for storing a variety of materials. Their combination of strength, affordability, and durability makes them a versatile and reliable solution for many storage applications.

- HDG panels are produced using standard molds. Common panel sizes include 1.22 × 1.22 m, 1.0 × 1.0 m, 1.0 × 0.5 m, and 0.5 × 0.5 m.
- The maximum tank height is 5 meters. If the height exceeds 5 meters, external I-beam reinforcement is required.
- Panel thickness ranges from 2-5 mm, depending on the tank’s design height and pressure resistance requirements.
- It can be used as an overhead water tank, underground water tank, or insulated water tank.
