Structural Support
Structural support systerm is the most important accessories for water tanks，such as lacing bar and vertical support rod，Lacing bar transfers tensile loads from the upper sections of the tank to the foundation, reducing stress on wall panels. vertical rods are designed to handle compressive and tensile forces from above. They enhance overall tank stability, especially in regions prone to seismic activity or extreme weather.

Accessories
The type and size of pipe connections for the water tank can be customized according to customer requirements. By default, we will provide at least four types of flanges, including the inlet flange, outlet flange, drain flange, and overflow flange. Additionally, we will supply a manhole cover, an air vent, both internal and external ladders, a water level meter, and other necessary accessory fittings. if you require any customized fittings, we can discuss and confirm the details.
GRP (Glass Reinforced Plastic) tanks are versatile solutions for numerous applications. They safely store potable water without affecting taste or odor. In firefighting systems, they offer a dependable water reserve. Their corrosion resistance makes them ideal for agricultural irrigation and various industrial processes, including chemical storage. These tanks are also perfectly suited for underground installation and can efficiently handle hot liquids.
A rectangle galvanized steel water tank is a storage container made from steel sheets coated with a layer of zinc (galvanized) to prevent rust and corrosion. Its rectangular shape allows for efficient space utilization, especially in tight or urban environments.
Inspect annually for rust, dents, or leaks.
Clean the interior every 2–3 years (more often if storing non-potable water).
Keep the lid sealed to prevent contamination and mosquito breeding.
Check and clean inlet/outlet screens regularly.
