GALVAGRID® PYLON™ re-galvanize electrical pylons and towers.
0,00 €
Galvanic coating for high-voltage towers and pylons, both new and existing, providing C5H-level protection.
The ambient-temperature GALVAGRID® galvanizing coating uses a 99.995% pure zinc organic formula to create an active electrochemical bond with the base metal. Applied to telecom towers and electrical pylons, it forms a galvanic couple delivering a potential equivalent to hot-dip galvanizing or doubles the lifespan of new galvanized coatings.

Description
Re-galvanize at ambient temperature or double the lifespan of your new hot-dip galvanization
The ambient-temperature galvanizing coating, GALVAGRID® PYLONE™ Rust Anode Primer™, provides cathodic protection equivalent to C5H, C5HV, or CX standards, even in saline environments. GALVAGRID® PYLONE™ is used to either double the lifespan of new standard hot-dip galvanization or restore aging high-voltage towers and communication antennas showing signs of rust, without the need for dismantling. This is referred to as ambient-temperature galvanizing.
This technology was exclusively used by NATO military forces from 1954 to 2003 under GALVATECH 2000. Since 2003, it has been widely adopted in the private sector, with numerous international references in the energy, maritime, petrochemical, and transportation industries. SYNERDIS is the North American representative for the electrical energy sector.
Advantages of GALVAGRID® PYLONE™
- Not a paint: This galvanic coating enhances the self-healing properties of hot-dip galvanized coatings on metallic structures.
- Highly durable: Offers exceptional resistance to scratches, abrasion, and friction, unlike traditional paint coatings.
- Versatile application: Can be applied in workshops or directly on-site.
- Flexible and tough: Accommodates thermal expansion and metal deformation without cracking.
- Primer-compatible: Can be overcoated with most paint systems (primarily epoxies and urethanes), allowing it to serve as a primer.
- Seamless bonding: Integrates with existing hot-dip galvanization or metallization, restoring cathodic protection potential through ambient-temperature recharging.
- Duplex system: Extends anti-corrosion protection up to C5H for new hot-dip galvanization.

Use and maintenance
Before application of GALVAGRID:
Please consult us for personalized support and an operational GALVAGRID® application procedure tailored to your specific configuration. NORTHBRIT and SPI provide assistance during the preparation phase as well as on-site implementation.
Each application is unique, but the basic rules for applying GALVAGRID® include the following minimum requirements:
- Ensure the application surface is clean and free of zinc oxide, loose rust, corrosion (mill scale), oil, grease, or any other chemical contamination.
Application of GALVAGRID® PYLONE:
- Apply the GALVAGRID® coating directly to:
- Existing galvanization,
- A metallized surface, or
- Steel cleaned of all loose rust and mill scale.
- The product is ready for use and can be applied using:
- A brush,
- A roller,
- A spray gun, or
- An airless sprayer.
Responsibility for use:
Failure to follow proper application practices and to address site anomalies or defects is entirely the responsibility of the equipment owner.
