Korea Type GRP Water Tank Features?
Material:
Made from Glass Reinforced Plastic (GRP), also known as Fiberglass Reinforced Plastic (FRP), which is highly durable and corrosion-resistant.
Modular Panel Design:
Typically constructed using modular panels, making it easy to customize the size and shape to meet specific requirements.
Hygienic & Safe for Drinking Water:
Manufactured to meet hygienic standards, ensuring clean and safe water storage.
Non-toxic and does not leach harmful substances into the water.
Corrosion & UV Resistance:
Unlike steel tanks, GRP tanks do not rust and are resistant to UV radiation, making them suitable for outdoor use.
Lightweight & Easy Installation:
Compared to concrete and steel tanks, GRP tanks are lighter, making transportation and installation more convenient.
Applications:
Used in municipal water supply, fire-fighting systems, agriculture, commercial buildings, and industrial facilities.

Material: Usually made of EPDM, PE, PU, or silicone foam, offering waterproof, weather-resistant, UV-resistant, and high-temperature-resistant properties.
Application: Essential for modular water tank assembly, ensuring a secure and watertight seal.
- Korea GRP Panel
Function: A high-strength, lightweight panel used for constructing GRP (Glass Reinforced Plastic) water tanks.
Material: Fiberglass reinforced plastic, known for its corrosion resistance, durability, and lightweight nature.
Application: Commonly used in industrial, commercial, and municipal water storage applications, ensuring long-term performance in various environmental conditions.
- Stainless Steel Flanges
Function: Used for connecting pipes and fittings to the water tank, ensuring a secure and leak-proof joint.
Material: Stainless steel (SS304/SS316), offering high corrosion resistance.
Application: Suitable for both potable water and industrial applications, ensuring reliable water flow and system integration.
- External Ladder
Function: Provides safe access for maintenance and inspection of the water tank.
Material: Galvanized steel, stainless steel, or aluminum, with optional anti-slip rungs.
Application: Installed on large tanks where regular inspections or cleaning are required, compliant with safety regulations.
- C-Channel Skid Base
Function: Serves as a structural foundation for the water tank, elevating it off the ground to prevent corrosion and improve stability.
Material: Hot-dip galvanized steel or stainless steel, providing rust resistance and durability.
Application: Used in industrial and commercial water tanks where a strong base is required to distribute load evenly.
- Internal Lacing Bar Board
Function: Strengthens the internal structure of the tank, preventing deformation due to water pressure.
Material: Galvanized steel or stainless steel.
Application: Essential for large or high-capacity water tanks, ensuring long-term structural integrity.
- Lacing Bar
Function: Provides additional reinforcement and bracing inside the tank, supporting panels against internal water pressure.
Material: Galvanized steel or stainless steel, designed for heavy-duty applications.
Application: Used in modular panel water tanks, ensuring high durability under various pressure conditions.
- Adjustable Support Base (Optional)
Function: Provides adjustable height and leveling support for the water tank, especially on uneven ground.
Material: Galvanized steel or stainless steel, with adjustable bolts for precise height control.
Application: Ideal for installations on irregular terrains, offering flexibility and stability.
