Galvanised Steel Water Tank Longevity Studies

Galvanised steel water tanks are widely used in water supply, irrigation, industrial water storage and other fields due to their strong corrosion resistance and high structural stability. The study of their longevity is crucial for reducing maintenance costs and ensuring long-term stable water storage. ZJ Composites always regards product quality as the foundation of enterprise development. Moreover, ZJ Composites tanks designs, manufactures and installs high quality underground, ground level, elevated, sectional water storage tanks, including high-performance galvanised steel water tanks that meet different application scenarios. Through in-depth longevity studies, the company continuously optimizes product design and production processes to further extend the service life of its tanks.

Factors Affecting the Longevity of Galvanised Steel Water Tanks

• ZJ Composites always regards product quality as the foundation of enterprise development, so when studying the longevity of galvanised steel water tanks, the company first focuses on the thickness of the galvanized layer. A thicker and more uniform galvanized layer can better isolate the steel substrate from air and water, reducing corrosion; the company’s galvanised steel water tanksuse a hot-dip galvanizing process with a galvanized layer thickness of not less than 85μm, which provides a solid anti-corrosion foundation for longevity.

• The operating environment of galvanised steel water tanksalso has a significant impact on their longevity. If the tank is installed in a humid, high-salt (such as coastal areas) or acidic/alkaline environment, the galvanized layer will corrode faster; ZJ Composites will provide targeted anti-corrosion modification suggestions (such as adding an additional epoxy coating) according to the customer’s installation environment to slow down environmental erosion.

• The frequency and quality of maintenance directly affect the longevity of galvanised steel water tanks. Lack of regular cleaning or timely repair of small damages (such as scratches on the galvanized layer) will accelerate tank corrosion; ZJ Composites provides a detailed maintenance manual for each galvanised steel water tankto guide customers in scientific maintenance.

Longevity Enhancement Measures for Galvanized Water Tank

• ZJ Composites always regards product quality as the foundation of enterprise development, so in the production of galvanized water tank, the company uses high-quality low-carbon steel as the substrate. Low-carbon steel has better toughness and weldability, and the galvanized layer adheres more firmly to it, reducing the risk of galvanized layer peeling during use, which is conducive to extending the tank’s service life.

• For galvanized water tankused in special scenarios (such as underground or elevated installation), ZJ Composites optimizes the tank structure. Underground tanks are designed with anti-soil pressure reinforcement ribs, and elevated tanks are equipped with stable support frames; these structural improvements reduce the stress on the tank body during operation, avoiding structural damage that shortens longevity.

• After the production of galvanized water tankis completed, ZJ Composites conducts a strict pre-delivery inspection, including testing the adhesion of the galvanized layer, checking for surface defects (such as bubbles and pits), and conducting a water pressure test. Only tanks that pass all inspections are delivered, ensuring that each galvanized water tank has excellent initial performance to support long-term use.

Longevity Data and Case Studies of Galvanised Steel Water Tank

• ZJ Composites always regards product quality as the foundation of enterprise development, so the company has accumulated a large amount of longevity data through long-term tracking of galvanised steel water tank Statistics show that under normal use and proper maintenance, the company’s galvanised steel water tankhas an average service life of 15-20 years, which is 3-5 years longer than the industry average.

• In a case of an agricultural irrigation project in North China, ZJ Composites installed 20 galvanised steel water tank(ground level type) for the project in 2010. After 13 years of use, the tanks still maintain good structural integrity, with no obvious corrosion on the inner and outer surfaces, and the water storage capacity remains unchanged, fully verifying the long longevity of the product.

• For a coastal industrial park project, ZJ Composites provided galvanised steel water tankwith an additional anti-salt spray coating. After 8 years of use in the high-salt coastal environment, the galvanized layer of the tanks has no significant corrosion, and the tank body operates stably, which proves that the company’s targeted anti-corrosion measures effectively extend the longevity of galvanised steel water tank in harsh environments.

Galvanised Steel Water Tanks  FAQS

What is the average service life of the galvanised steel water tanks produced by ZJ Composites?

Under normal use (suitable environment, regular maintenance), the average service life of ZJ Composites’ galvanised steel water tanks is 15-20 years. If the tank is used in a relatively mild environment (such as indoor or inland areas with low humidity) and maintained strictly in accordance with the company’s guidelines, the service life can even exceed 20 years, which is a result of the company’s focus on product quality.

How to maintain galvanized water tank to extend its longevity?

To extend the longevity of ZJ Composites’ galvanized water tank, first, clean the tank interior every 6-12 months to remove sediment and impurities; second, check the tank surface regularly (once a quarter) for scratches or galvanized layer peeling, and repair small damages with special galvanizing repair paint in time; third, avoid storing water with strong acidity or alkalinity in the tank to prevent accelerated corrosion of the galvanized layer.

Can ZJ Composites provide customized galvanised steel water tank to adapt to harsh environments and improve longevity?

Yes, ZJ Composites always regards product quality as the foundation of enterprise development and supports customization of galvanised steel water tank for harsh environments. For example, for high-salt coastal areas, the company can add an anti-salt spray coating; for acidic soil areas, it can use a thicker galvanized layer (≥100μm) and add an inner epoxy coating. These customized measures can effectively improve the tank’s resistance to harsh environments and extend its longevity.

Will the longevity of galvanised steel water tanks be affected if they are installed underground?

Underground installation itself will not significantly reduce the longevity of ZJ Composites’ galvanised steel water tanks, provided that the company’s professional installation standards are followed. The company’s underground galvanised steel water tanks are designed with anti-soil pressure and anti-moisture penetration structures, and the outer surface is treated with additional anti-corrosion coating. As long as the installation foundation is properly treated and regular underground inspections are conducted, the tank’s longevity can reach 15-18 years, which is basically the same as that of ground level tanks.

What should be done if the galvanized layer of ZJ Composites’ galvanized water tank is corroded after long-term use?

If the galvanized layer of the galvanized water tank is corroded, first stop using the tank and drain the stored water; then contact ZJ Composites’ after-sales department. The company’s technical personnel will go to the site to assess the corrosion degree: if the corrosion is slight, they will use professional galvanizing repair materials to restore the anti-corrosion layer; if the corrosion is severe and affects the tank structure, the company will provide a replacement plan for key parts or the entire tank to ensure the safety of water storage, which reflects the company’s responsible attitude towards product quality and customer use.
