Water Storage Tank
Composite Water Tank | FRP / GRP Polyester Water Storage Systems
Composite water tanks are modern storage solutions designed for the safe storage of drinking water, utility water, rainwater, and industrial liquids. Manufactured from fiber-reinforced polyester (FRP / GRP), these tanks provide superior durability, hygiene, and long service life.
Sterplas composite water tanks offer a strong alternative to concrete and metal tanks by providing corrosion resistance, leak-proof structure, and minimal maintenance requirements. Their lightweight yet robust construction allows for flexible installation across residential, commercial, and industrial applications.
FRP water storage tanks are produced using glass fiber-reinforced polyester resin systems, ensuring a hygienic inner surface and long-term structural stability.
FRP Water Tanks:
-
Do not rust
-
Do not rot
-
Are resistant to chemicals
-
Maintain structural integrity for decades
Thanks to these properties, they are widely preferred for both potable water storage and industrial water storage applications.
