HDG Steel Water Tank

The HDG steel water tank system is constructed from hot-dip galvanized steel (HDG) and is widely used for building water supply, fire protection, and industrial water storage. It mainly consists of galvanized steel plates, sealing strips, bolts, support structures, and other components. Designed modularly, the tank allows flexible assembly tailored to specific needs. The galvanized coating on the steel plates typically measures between 80 and 100 microns, providing excellent corrosion resistance and extending the tank's service life to over 20 years. With capacities adjustable from 1 cubic meter to several hundred cubic meters, these tanks are suitable for a wide range of applications.

Durability

The HDG steel water tank is constructed from hot-dip galvanized steel plates treated with a high-temperature galvanizing process. This creates a zinc layer 80–100 microns thick on the surface, effectively protecting the steel from moisture and oxygen exposure to prevent corrosion of the steel core. This protective layer significantly enhances the tank's durability, giving it a service life exceeding 20 years. It is ideal for long-term water storage applications such as high-rise building water supply, fire water tanks, and other demanding scenarios.

Modular Design

The tank features a modular design, enabling standardized steel plates to be precisely connected using bolts and sealing strips. Installation requires only conventional tools and minimal labor without the need for specialized equipment. This modular system allows flexible installation even in constrained or irregular spaces like basements and rooftops. Additionally, the capacity can be easily adjusted from 1 cubic meter to several hundred cubic meters, accommodating water storage needs of varying scales.

Good Sealing Performance

Equipped with high-quality sealing strips and bolts, the HDG steel water tank ensures tight module connections, forming a highly airtight and leak-proof structure. The sealing strips are made from anti-aging, corrosion-resistant rubber that maintains elasticity despite temperature and humidity fluctuations. Bolts securely fasten modules to prevent vibration or loosening, preserving a reliable seal. This exceptional anti-leakage capability makes the tank especially suitable for applications with stringent water safety requirements, such as fire water and domestic water storage.

Excellent Temperature Resistance

The HDG steel water tank operates reliably within a temperature range of -40℃ to 80℃. This stability is due to the low thermal expansion coefficient of galvanized steel, preventing significant deformation in extreme temperatures. As a result, the tank maintains structural integrity through harsh winters and hot summers, making it an excellent choice for municipal and industrial water supply systems.
