These modular water storage tanks are assembled from fiberglass-reinforced plastic panels using bolted connections, Hot-Dipped Galvanized (HDG) external bracing and SS304/SS316 stainless-steel internal tie-rods or stays. Installation typically takes 2–4 days, depending on site hoisting access and preparation of the concrete plinth. The tanks are suitable for potable water storage, with supply and installation primarily across Peninsular Malaysia.

FRP and GRP are interchangeable terms for the same glass-fiber reinforced polymer composite material in this product context. The sectional construction allows the tanks to be transported through restricted access routes and assembled on site.

Key Features and Benefits

Modular Sectional Construction

FRP/GRP sectional panel tanks are assembled from individual panels using bolted connections with internal and external bracing. The modular design allows tank capacity to be configured according to the required water volume and available installation space.

Lightweight Construction

The tanks weigh approximately one-third as much as an equivalent steel tank. This can reduce structural dead load, which is particularly relevant for elevated slabs and high-rise rooftop installations.

Non-Corrosive Construction

FRP/GRP panels are non-corrosive and do not rust internally or externally. This helps support long-term water storage without the corrosion issues associated with steel tanks.

Suitable for Potable and Other Suitable Water Storage

The tanks use a food-grade internal gelcoat and are suitable for potable municipal drinking water and treated cold-water storage. They can also be used for rainwater harvesting and non-corrosive process water at ambient temperatures, subject to the suitability of the stored liquid and project requirements.

Designed for Restricted Access

The sectional construction allows individual panels to be transported through relatively tight access routes and freight lifts. Assembly is completed on site without hot-works or structural welding.

Fast Installation

Standard configurations typically require 2–4 days for installation, depending on site hoisting access and whether the required concrete plinth foundation has been prepared. The stated installation scope covers material supply and on-site panel assembly.

UV-Stabilized Material

The FRP/GRP panels use polyester resin with UV stabilization, supporting their use in outdoor installations.

FRP/GRP vs Steel Water Tanks

FRP/GRP sectional panel water tanks and steel water tanks can both be used for water storage, but their construction, weight and corrosion characteristics differ. For projects where transport access, structural loading and corrosion resistance are important considerations, the differences may affect tank selection.

Installation Requirements

FRP/GRP sectional panel water tanks are assembled on site from individual panels using bolted connections and internal and external bracing. Standard configurations typically require 2–4 days for installation, depending on site hoisting access and the availability of a prepared concrete plinth foundation.

The installation scope covers material supply and on-site panel assembly. The customer is responsible for providing the required concrete plinth foundation before installation.

The sectional construction also allows tank panels to be transported through tight access routes and freight lifts, making the system suitable for locations where transporting a fully assembled tank would be difficult.

For standard installations, the concrete plinth should be prepared according to the requirements of the selected tank configuration.

5-Step Site Assembly Workflow

1. Inspect and verify the concrete plinth — inspect and verify the client-prepared concrete plinth before tank assembly begins.
2. Offload and hoist components — offload the tank panels and components and hoist them to the designated installation location, such as a rooftop, plant room or ground-level installation area.
3. Assemble the base and panels — assemble the base skid and bolt the sectional panels together using specialized synthetic sealant gaskets.
4. Install bracing and fittings — install the internal and external bracing stays, roof covers and standard access fittings.
5. Conduct the hydrostatic holding test — complete the hydrostatic holding test, including a 24-hour leak test, before formal handover and commissioning.

Maintenance and Inspection

Routine maintenance should include an annual internal gelcoat inspection and scheduled inspection of the internal SS304/SS316 tie-rods and external HDG bracing. Annual draining, sediment flushing and sanitization should also be carried out in accordance with applicable local health and water-authority guidelines.
