GRP/FRP Sectional Water Tank

Integrated Water Pressure Solutions

The GRP/FRP Sectional Water Tank provides a non-metallic, lightweight option within Mingxing's diverse storage solutions. It is favored where structural load is the main constraint, such as on existing building rooftops.

The low-weight GRP tanks are often integrated with our compact Roof Pressure Stabilizing Pump Station and Vertical Multi-Stage Fire Pumps to minimize overall rooftop dead load while maintaining high performance and thermal efficiency.

Composite Material and Insulating Properties

Glass-Reinforced Plastic (GRP), also known as Fiber-Reinforced Plastic (FRP), sectional tanks are constructed from panels molded from a composite material of glass fibers embedded in a thermosetting resin matrix (usually polyester). This composite material is lightweight, non-corrosive, and possesses excellent thermal insulating properties.

The panels are bolted together using non-corrosive bolts (often 316 SS) and sealed with rubber gaskets. The GRP tank is inherently immune to rust and is a popular choice for water storage where lightweight, non-metallic construction and excellent thermal stability are required.

Application Fields

Rooftop water storage in high-rise buildings due to their low weight and resistance to structural overloading.
Storage of potable water where thermal stability (preventing heating/freezing) is critical.
Holding tanks for high-purity process water in electronics or pharmaceutical industries.
Fire water reserve in corrosive industrial environments (e.g., acid vapor exposure).
Coastal regions where salt corrosion is a major issue for steel tanks.

Engineering and Custom Fabrication

Panels are manufactured using the Sheet Moulding Compound (SMC) or compression molding process, ensuring consistent thickness and glass/resin ratio for optimal strength.

Customization Scope: Specific resin formulations for chemical or high-temperature resistance, custom panel coloring, and the integration of internal baffles for seismic stability.

We provide stress-analysis reports certifying the tank's suitability for specific wind or seismic zones and structural load calculations.

Core Operational Characteristics and Client Value

Non-Corrosive: The composite construction is entirely non-metallic, eliminating rust and electrolysis issues, ensuring a long, maintenance-free lifespan.
Low Thermal Transfer: Acts as a natural insulator, minimizing temperature variation of the stored water and reducing the cost of heating/cooling the reserve.
Lightweight: Drastically reduces the structural load on building foundations and rooftops compared to steel or concrete tanks.
Hygienic Safety: The smooth internal surfaces and non-toxic resin formulation are ideal for contact with potable water, with colored panels used to block light and prevent algae growth.

Component Materials Selection Guide

Resin: Isophthalic or vinyl ester resin is used, with FDA/NSF approved gel-coat on the interior surface for potable water contact.
Bolts: External bolts are often 304 or 316 Stainless Steel, with internal bolts (if required) completely encapsulated in GRP.
Internal Bracing: Non-metallic GRP tie-rods or high-grade stainless steel rods are used, often requiring internal panel ribbing for support.
Gaskets: Non-toxic EPDM or Neoprene rubber, UV stabilized for external exposure.

Scenario-Based FAQs

Q: Can GRP tanks be used for hot water storage?
A: Standard GRP tanks are typically limited to 50∘C to 60∘C. Higher temperature applications require specialized, more expensive high-temperature vinyl ester resins and custom testing.

Q: Are GRP tanks prone to leakage over time?
A: The sectional joints, relying on gaskets, are the potential leak points. High-quality molding ensures precise panel alignment, and the non-corrosive structure protects the joints. Proper installation and foundation leveling are critical for long-term sealing integrity.

Q: How do GRP tanks handle sunlight exposure and UV degradation?
A: Exterior surfaces are protected by a UV-stabilized gel coat. While the structure is resilient, excessive UV exposure over decades can cause surface chalking, but this does not typically affect the structural integrity unless the coating is compromised.
