Why GRP Water Tanks?

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 growing inside the tank.

Features of GRP Water Tanks

GRP is not only non-adhesive, simple to work with, but it is also clean.
GRP can be mounted on high-temperature molds, and through high pressure from a large hydraulic press, it can produce products with subtle surface and high strength.
GRP has a constant length of glass fiber contents, l-inch fiber, uniform mechanical strength, and high fallibility and fluidity.
The surface of GRP is smooth and graceful, and GRP can shorten the finishing procedure as it has an excellent coating.
GRP can easily correct deformities with rib, boss, and insert unlike the traditional use of RFP.
GRP can form molds with different thicknesses and has high mechanical strength.
