Why Hot-Dip Galvanized?
01 — Hot-Dip Galvanized Protection
Steel panels are protected with a zinc coating to improve resistance against corrosion.
02 — Strong Steel Structure
Q235 carbon steel provides a rigid structure for large-capacity water storage.
03 — Modular Bolted Design
Individual panels can be transported and assembled efficiently at the installation site.
04 — Easy Maintenance
The sectional structure makes inspection, maintenance and component replacement convenient.
Hot-dip galvanized water tank accessories
Water tank accessories, which are critical components of the tank, are categorized into internal and external parts. We offer a range of materials, including galvanized steel and stainless steel (SS304, SS316). Stainless steel is recommended for internal accessories when storing potable water, whereas either material is suitable for non-potable applications.

Frequently Asked Questions
What is a hot dip galvanized steel water tank?
A hot dip galvanized steel water tank is a sectional water storage tank manufactured from carbon steel panels protected by a hot-dip galvanized coating.
What material are galvanized water tanks made from?
GOOYI galvanized steel water tanks primarily use Q235 carbon steel panels with hot-dip galvanized surface protection.
Are galvanized steel tanks suitable for outdoor installation?
Yes. The galvanized coating provides corrosion protection for outdoor water storage applications. The final design should consider the local environment, wind load, foundation, and project requirements.
Can galvanized steel tanks be used for firefighting water?
Yes. Galvanized steel sectional tanks are commonly used for fire water storage systems, subject to the applicable project standards and engineering requirements.
What capacity galvanized steel water tanks can you supply?
GOOYI supplies galvanized steel water tanks from approximately 0.5 m³ to 3,000 m³, with the final dimensions determined by the required capacity and structural design.
How are galvanized steel water tanks installed?
The tank panels are transported separately and assembled at the project site using bolts, gaskets, internal tie rods, external bracing, and other structural components.
