Glassfiber Reinforced Epoxy (GRE) Piping
Glassfiber Reinforced Epoxy (GRE) is a lightweight yet extremely strong composite material that provides a long-lasting solution for water and energy distribution in commercial greenhouses.
GRE piping for commercial greenhouses in the USA
Efficient and reliable piping systems are critical in high-tech greenhouse operations. For U.S. growers, durability and low maintenance are key to keeping operational costs under control. VB specializes in supplying and installing GRE systems tailored to large-scale horticulture projects across the United States.
GRE is a composite material made of glass fibers reinforced with epoxy resin. This combination creates a piping system that is:
- Strong and pressure-resistant
- Lightweight and easy to install
- Corrosion-resistant even under harsh water conditions
These characteristics make GRE particularly suitable for modern greenhouses, where reliability and long service life are essential for continuous production.
Serving U.S. growers with complete water and energy solutions
VB offers American farmers and growers the most advanced commercial greenhouse solutions in the world. GRE piping is part of a complete water and energy infrastructure. Check out our related solutions below.

GRE compared to traditional greenhouse piping
Compared to steel or PVC, GRE offers multiple benefits:
- Corrosion resistance: unaffected by high salt or fertilizer concentrations
- Lightweight installation: faster setup and lower transportation costs
- High pressure performance: capable of withstanding multi-bar systems without deformation
- Extended lifespan: significantly less wear compared to metal pipes
- Lower maintenance costs: no rust and fewer replacements required
Performance under high pressure and aggressive conditions
GRE is engineered for high-pressure greenhouse applications and remains stable in systems with elevated EC levels, low pH, or aggressive fertilizers. This makes it ideal for recirculating irrigation systems and hot water pipelines, ensuring consistent performance even under demanding conditions. GRE can also be seamlessly integrated with existing infrastructure. Using specialized joints and connectors, it can be combined with steel, PVC, or PE piping systems, allowing hybrid setups in both new builds and retrofits.
Maintenance and lifespan expectations
In large-scale greenhouse projects, GRE offers a service life of over 25 years, even under intensive use. Since it does not corrode and requires minimal upkeep, maintenance is limited to standard inspections and cleaning. This makes GRE one of the most cost-effective piping solutions for U.S. greenhouses focused on long-term reliability and efficiency.

GRE Piping FAQ's
What is GRE and why is it suitable for greenhouses?
GRE is a composite material made of glass fibers reinforced with epoxy resin. It creates a piping system that is strong and pressure-resistant, lightweight and easy to install, and corrosion-resistant even under harsh water conditions. That makes it particularly suitable for modern greenhouses, where reliability and long service life are essential.
How does GRE compare to steel or PVC?
GRE is unaffected by high salt or fertilizer concentrations, installs faster thanks to its low weight, withstands multi-bar systems without deformation, wears significantly less than metal pipes, and requires lower maintenance: no rust and fewer replacements.
Can GRE handle aggressive fertilizers and high pressure?
Yes. GRE is engineered for high-pressure applications and remains stable in systems with elevated EC levels, low pH, or aggressive fertilizers, making it ideal for recirculating irrigation systems and hot water pipelines.
Can GRE be combined with my existing piping?
Yes. Using specialized joints and connectors, GRE can be combined with steel, PVC, or PE piping systems, allowing hybrid setups in both new builds and retrofits.
How long does GRE piping last?
In large-scale greenhouse projects, GRE offers a service life of over 25 years, even under intensive use. Maintenance is limited to standard inspections and cleaning.
