Hot Dipped Galvanized Tanks for Industrial and Commercial Use

What are Hot Dipped Galvanized Water Tanks?
Hot dipped galvanized tanks provide one of the most reliable and durable solutions for long-term water storage across industrial, commercial and utility environments. Manufactured from high-grade steel and protected with a full hot-dip galvanization process, these tanks deliver outstanding corrosion resistance, structural strength and service life, even in demanding outdoor conditions.
Raven American Tanks supplies hot dipped galvanized tanks engineered to meet strict performance, safety and longevity standards, making them ideal for facilities that require dependable, high-capacity water storage with minimal maintenance demands.
What are Hot Dipped Galvanized Tanks?
Hot dipped galvanized tanks are steel water storage systems coated inside and outside with a protective zinc layer. During the galvanization process, the tank components are fully submerged in molten zinc, forming a metallurgically bonded coating that resists corrosion far more effectively than standard painted or sprayed steel.
This coating protects not only the surface but also edges, welds and hard-to-reach areas, ensuring long-term durability and superior resistance to rust, moisture, chemicals and environmental exposure. These tanks are commonly used for storing potable water, fire reserve water, process water, stormwater and general-purpose storage in industrial and commercial settings.
Why Choose Hot Dipped Galvanized Tanks?
HDG tanks provide several performance advantages that make them suitable for long-term, high-demand applications:
1. Exceptional Corrosion Resistance
The zinc coating acts as a physical barrier and a sacrificial layer, preventing corrosion even if the surface is scratched or damaged. This makes HDG tanks particularly effective in outdoor or moisture-prone environments.
2. Long Service Life
Hot-dip galvanization provides up to several decades of protection, reducing the need for recoating or refurbishment. Many facilities choose HDG tanks because they offer consistent performance with minimal long-term maintenance.
3. Strong Structural Integrity
Steel construction ensures the tank can handle large volumes, hydrostatic pressure and fluctuating water levels. Reinforced bracing and precision-engineered steel panels maintain stability under industrial operating conditions.
4. Fast and Flexible Installation
Most HDG tanks are supplied as modular, bolted components that can be assembled quickly on-site. This allows installations in restricted-access areas and remote locations where transporting a fully assembled steel tank is not feasible.
5. Cost-Effective Water Storage
HDG tanks offer a strong balance between durability and cost efficiency. Their long lifespan, low maintenance requirements and simple installation process reduce overall lifecycle costs.

Applications of Hot Dipped Galvanized Tanks
These tanks are suitable for a wide range of uses, including:
- industrial process water
- commercial building reservoirs
- utility and municipal storage
- fire water reserve tanks
- agricultural and irrigation systems
- stormwater catchment
- mining and remote camp applications
- potable and non-potable water storage
HDG systems perform reliably in both permanent and semi-permanent installations.

FAQ
How long will galvanized water storage tanks last in the ground?
Hot-dip galvanized steel can last 10–12 years or more in harsh environments, including direct soil or seawater contact. Lifespan depends on factors like soil moisture, salinity, and exposure to air. Our HDG tanks feature corrosion-resistant coatings for extended durability in coastal and underground environments.
Is it safe to weld galvanized steel?
Welding galvanized steel is possible, but it requires proper ventilation and protective equipment. Heating the zinc coating releases toxic fumes, so workers must use specialized techniques and strict safety precautions. Pre-welding surface preparation is also essential for a clean, strong weld.
Why do we galvanize steel with zinc instead of aluminum?
Zinc offers superior sacrificial protection, meaning it corrodes before the steel underneath does, extending the structure’s life. Zinc bonds better to steel than aluminum and offers self-healing protection, ensuring long-term corrosion resistance.
What are the main advantages of an HDG water tank?
HDG (Hot-Dip Galvanized) water tanks offer excellent corrosion resistance, a long service life, and low maintenance requirements. The zinc coating resists harsh conditions, making these tanks ideal for indoor, outdoor, coastal, and industrial use.
