Corrugated Steel Water Tank

What is Corrugated Steel Water Tank?

The circular corrugated sectional metal steel water tank has two types according to raw material.

One is galvanized steel water tank (Z275 and G90 standard:275 g/m²).

One is zincalume steel water tank.

Above two water tanks are called water silos which is a cheaper option for water storing.Due to less metal parts with same capacity, it has the advantage of less price and easier installation.The tank is assembled by two main parts combined corrugated sheet for wall and food-grade tarpaulin or PVC inside for loading water.

The cylindrical corrugated metal steel water tank has a lifespan over 20 years which is an more economical, efficient and safer large water storage tank. It is suitable for all kinds of irrigation and domestic water and potable water tank, such as greenhouse irrigation, greenhouse rainwater collecting, temporary water storage at construction sites etc.

Zinc-Aluminum Water Tank VS Corrugated Galvanized Steel (CGS) Water Tank

1. Material and Durability

Zinc-Aluminum Tanks: These are made from an alloy that combines zinc and aluminum. They are known for their exceptional resistance to corrosion and longer lifespan, as aluminum creates a protective oxide layer, and zinc prevents rust.
- Pros: Excellent corrosion resistance, lightweight, and durable.
- Cons: Might be more expensive upfront compared to CGS.
Corrugated Galvanized Steel Tanks: These are made from steel coated with a layer of zinc to prevent rust. The corrugation adds structural strength.
- Pros: Strong structural integrity, affordable, and widely available.
- Cons: Zinc coating can wear off over time, leading to rust and reduced lifespan in harsh conditions.

2. Corrosion Resistance

Zinc-Aluminum: Superior corrosion resistance due to the combination of zinc and aluminum. Performs better in humid, salty, or aggressive environments.
CGS: Good corrosion resistance initially, but the zinc coating can degrade, especially if the tank is scratched, exposing the steel to rust.

3. Cost

Zinc-Aluminum: Generally more expensive due to its advanced alloy composition and better longevity.
CGS: More affordable, making it a cost-effective option for short- to medium-term use.

4. Maintenance

Zinc-Aluminum: Requires less maintenance because of its excellent resistance to rust and corrosion.
CGS: Needs periodic inspections and maintenance, especially in environments where the zinc coating might deteriorate.

5. Aesthetic and Structural Considerations

Zinc-Aluminum: Sleeker and modern appearance, often used in settings requiring a visually appealing option.
CGS: Has a more industrial look due to the corrugation and is better suited for rural or rugged environments.

Advantages of Corrugated Steel Water Tank

1. The price is better than that of a concrete water tank.

2. Corrugated sheets assemble it, much easier to install.

3. It is detachable and movable for multiple uses.

4. It is rust-resistant and has over 20 years of lifespan.

5 . Transportation is so competitive due to pieces loading.

6 . Wide application for drinking water and fishing breeding and farming etc.
