Raw water—sourced from rivers, lakes, wells, or rainwater harvesting—is the lifeblood of municipal treatment, industrial processing, and agricultural irrigation. However, untreated water is inherently unpredictable, containing sediments and minerals that can compromise standard storage vessels.
As a premier China Galvanized Steel Raw Water Storage Tank manufacturer, Shijiazhuang Zhengzhong Technology (Center Enamel) provides modular, high-performance containment systems engineered to withstand these challenges. With a global footprint spanning 100+ countries, our hot-dip galvanized (HDG) bolted tanks offer the most cost-effective and durable solution for raw water management.
The primary defense of our industrial water storage solutions in China is the Hot-Dip Galvanizing process. Unlike surface-level paints, HDG involves immersing pre-fabricated steel panels into a bath of molten zinc, creating a metallurgical bond.
● Self-Healing Properties: If the zinc coating is scratched, it acts as a sacrificial anode, protecting the underlying steel from oxidation.
● Modular Flexibility: Our galvanized bolted tanks for raw water are prefabricated for rapid on-site assembly, requiring no welding or heavy machinery.
● Seismic and Wind Resistance: Engineered to AWWA D103-09 standards, our tanks provide formidable structural integrity against environmental loads.
To provide corrosion-resistant raw water containment, Center Enamel adheres to strict international metrics. Providing specific data like zinc thickness is a high-authority signal for Google ranking.

Center Enamel’s solutions are pivotal in supporting foundational water management strategies worldwide. A recent example includes our May 2024 East Timor project, where galvanized tanks with Aluminum Flat Top Covers were selected for their resilience in high-humidity tropical climates.
1. Potable Treatment Input: Buffering capacity for municipal purification.
2. Mining Operations: Durable reserves for dust suppression and mineral processing.
3. Rainwater Harvesting: Large-scale sustainable collection for agriculture.
4. Fire Water Storage: Reliable reserve for industrial safety compliance.
Typically, galvanized bolted tanks for raw water have a service life of 20 to 30 years. Longevity depends on the environment and the zinc coating thickness (Standard 85–100 $mu m$). Our tanks utilize Grade 8.8 or 10.9 high-tensile bolts with plastic capped heads to ensure the hardware lasts as long as the panels.
Zinc is highly effective between pH 6.0 and 9.0. If your raw water is highly acidic (pH below 6.0), the zinc layer may dissolve prematurely. For these conditions, we recommend our Glass-Fused-to-Steel (GFS) technology, which offers superior chemical resistance.
Since 2008, Center Enamel has been a global leader in bolted tank technology. We are the first manufacturer in China to produce Glass-Fused-to-Steel tanks and the most experienced professional bolted tanks manufacturer in Asia. Our systems are certified to ISO9001, NSF61, WRAS, and FM Global standards, ensuring that your raw water project is backed by decades of engineering expertise.
