Features of Internally Reinforced System
-
Excellent Hygienic Conditions
- - Internal tie-rod of water tank is coated with PE and internal bracket is coated with powder.
- - Internal Bolt for tie-rod and bracket is coated with epoxy after fastening.
- - Prevented rust appearance as Chlorine GAS stay through external assembly bolts(HDG) added PVC bolt-caps of water tank.
-
Outstanding View
- - Prevented white peril or rust appearance through external assembly bolts added bolt-capsofWaterTank, and outstanding view.
-
Easy to Assembly
- - Easy to assembly through internal and external optimized options of reinforced system.
-
Best Structure Stability
- - SUNGIL CO., LTD's internally Reinforced System is verified structure stability of water tanks which have built in domestic and international sites for 20years.
2. External Reinforced GRP Water Tank
Externally Reinforced System
- By using external reinforcement bar at the exterior, it is minimizing internal reinforcement bar. Strengthened GRP water tank system is to simplify construction and reinforce cleanliness.
