Bolted panel tanks made from GRP/FRP (Glass/Fiberglass Reinforced Plastic) are a proven option for safe, long-life water storage. Their modular design allows rapid transport, fast site assembly, and easy capacity changes with minimal downtime.

What are GRP/FRP Bolted Panel Tanks?
These are sectional tanks built from prefabricated composite panels that are bolted and sealed on site. The approach reduces shipping volume, simplifies handling in restricted areas, and supports future expansion. Unlike welded tanks, sections can be replaced or added without major fabrication.
Key Advantages
- Corrosion resistant: Composite laminate resists rust, scale, and many chemicals.
- Lightweight yet strong: High strength-to-weight ratio reduces structural loads.
- Modular flexibility: Panels pass through standard access ways; capacity scales up or down.
- Hygienic interiors: Smooth, non-porous surfaces support potable water applications.
- Lower lifecycle costs: Faster installation and reduced coating/repair needs.
Typical Applications
- Potable water storage for residential, commercial, and municipal systems.
- Fire protection tanks aligned with relevant standards (e.g., AS 1851 usage context).
- Industrial process and utility water.
- Rainwater harvesting and reuse.
- Agricultural irrigation and livestock supply.
How GRP/FRP Panels are Manufactured
Panels are molded from fiberglass reinforcement and resin under controlled pressure and temperature. The process produces stiff, dimensionally stable sections with low water absorption.
At assembly, food-grade gaskets and specified torque patterns create a watertight, serviceable joint.
Cost & Sizing Factors
Project cost varies with capacity, geometry, design pressure, panel spec, internal lining/gasket type, foundation, and site access. In many cases, total installed cost is lower than welded steel or concrete due to reduced transport, lifting, and on-site fabrication time.
Installation Overview
- Prepare and level the foundation to engineering requirements.
- Deliver panels in compact, palletized form.
- Assemble panels with specified bolt patterns and seal system.
- Install internal components (baffles, roof, access ladder/platforms).
- Hydrotest and commission per the project specification.
Why Choose GRP/FRP Over Steel or Concrete?
- Weight: Lower dead load simplifies rooftop or elevated installations.
- Durability: Composite does not rust; UV-stabilized systems withstand harsh climates.
- Cleanability: Smooth, non-porous surfaces limit biofilm and residue.
- Adaptability: Modular design supports future relocation or capacity change.
When GRP/FRP May not be the Best Fit
- Extremely high temperature or specific chemical exposure outside resin compatibility.
- Unusual impact or abrasion conditions that require additional protection.
- Projects mandating a different material by regulation or legacy standard.
