Structure of Modular GRP Water Tanks are mainly composed of SMC molded GRP/FRP panels and hot-dip galvanized or stainless steel accessories. The most important structural components include the GRP panels and the internal support system, including tension rods and lacing bar(used to support the interior of the tank, distribute pressure, and ensure structural stability).
Main Structural Components Include:
1) Water Tank Surface Structure
Constructed by assembling standard-sized SMC molded panels, GRP panel sizes such as:
– 1000×1000 mm
– 1000×500 mm
– 500×500 mm
– 1500×500 mm
GRP Panel thickness options include: 5mm, 6mm, 7mm, 8mm, 10mm, 12mm, 14mm,
16mm, 18mm, etc., different layer panels will be design with different thickness, These
panels are assembled to form a rectangular water tank structure.

2) Internal Support System
Stainless steel or hot-dip galvanized lacing bar and steel support rods that provide internal structural support.
3) Pipe Connections
Pipe connections are made using pre-welded flange with various sizes, including
Inlet, outlet, bottom drain ,overflow ,The size and position of the flange ports can be
customized according to customer requirements.
4) Other Accessories
Bolts and nuts for connect GRP panels,Manhole cover, Internal and external ladders
Water level indicator, etc.
5) Water Tank Sealing Materials
A sealing belt is placed between the GRP panels to prevent leakage. Leak-proof materials such as leak sealing and glass glue.
6) Concrete Foundation
The concrete foundation consists of concrete strips arranged according to the spacing between GRP panel gap, It must have sufficient load-bearing capacity to support the total weight of the water tank when fully filled with water.
The concrete foundation needs to be constructed by the customer before installation. Our company will provide complete foundation drawings to the customer.
Additionally, the concrete foundation ensures a certain clearance beneath the tank bottom, providing space for the drain outlet; otherwise, the drain would need to be located on the side of the GRP water tank.
