Superior Material and Quality System Ensured Reliability
Tested and certified by SIRUM to SS 245: 1995 for its physical, chemical, microbiological and cytotoxicity properties. This Fiberglass Reinforced Polyester Thank is completely rust free, a factor
which greatly improves sanitation. Thus it is safe for portable water storage designated for human consumption. Its non-corrodable property greatly extend the life span of the tank and minimize maintenance.
Innovative in Providing an Everlasting Water Tank System
It is assembled by connecting independent angular panel with bolts and reinforced by external and internal bracing
It is modular that you can create the required and space available.
It is vigorously designed to withstand both hydrostatic and dynamic water pressure. Our designed safety factor bursting pressure exceeds six times its rated capacity.
High Pressure Hot Press Molding
FRP Water Tank panels are molded using High Pressure Hot Compression Matched Metal Mold method that gives good finishing and dimensionally accurate panels to ensure durable and long lasting tanks
Typical Assembly Tank
Material Finite Element Analysis
All critical components of Tanks undergo computerized Structural Non-Linear Finite Element Analysis at the design stage. Our design follows strictly to all Engineering Code of Practice applicable to Structural & Mechanical Disciplines
