The Special Feature of Hot Pressed GRP Sectional Water Tank are,

Intensity and Durability

Glass fiber Reinforced Panel is molded under condition of high temperature and pressure to maintain the best endurance. Since using stainless steel for inside structure and HOG steel for outside, it shows best performance against corrosion.

Excellent Hygiene

 No corrosion from panels and prevent bacteria increasing by isolating outside light.

Water tightness

 The joints are sealed with special sealing tape especially developed for water tank.

Heat Insulation and Dewdrops Prevention

The heat insulation panel with 3 layer structured improves heat insulation effect. Protect water from dewdrops and minimizes temperature variation of the stored water.

Dimensional Accuracy

GRP Sectional water tank panel’s size is changeless from the outside condition so assemble it accurately.

Various Capacity Design

Various sized panels are available in a limited space for the best way.

Easy to Assembly and Transporting

GRP Sectional panels make construction time shorter. Standardization panels make easier to move, carry in and transfer.
