Why GRP Water Tank

GRP Sectional Water Storage Tanks’ panels are obtained from the process of chopped fiberglass and unsaturated polyester resin under high pressure and temperature.

Panels are manufactured at a high tonnage press which molders heated up to 150 oC. Smooth, highly resistant, and cured panels are obtained through high molding and manufacturing technology.

PIPECO GRP panels are WRAS approved, which represents the highest global standards. Panels are also tested by TSE, in terms of health and nutrition regulations. GRP Panels are UV stabilized; therefore do not allow algae to grow inside the tank.


Features of GRP Water Tanks

GRP (Glass Reinforced Plastic) offers numerous advantages, as it is both non-adhesive and easy to handle, providing convenience during the manufacturing process. Moreover, GRP can be effectively molded on high-temperature molds, enabling the production of products with smooth surfaces and remarkable strength, achieved through the application of high pressure from a large hydraulic press. The clean and versatile nature of GRP makes it an ideal choice for a wide range of applications.
GRP (Glass Reinforced Plastic) exhibits consistent glass fiber content, with fibers of uniform length, resulting in a material with balanced mechanical strength and exceptional flexibility and fluidity. The surface of GRP is characterized by its smooth and elegant appearance, while its excellent coating capabilities allow for a streamlined finishing process, reducing the overall time required for completion.
Unlike the traditional use of RFP (Reinforced Fiberglass Plastic), GRP (Glass Reinforced Plastic) offers the advantage of easily correcting deformities through the use of rib, boss, and insert. Additionally, GRP allows for the formation of molds with varying thicknesses while maintaining high mechanical strength. This versatility and strength make GRP an ideal choice for a wide range of applications.
