Galvashield® N
-3-TMv_Photo_resized.png)
The original Galvashield® XP, commonly referred to as "the hockey puck," was first available with twin steel connection wires. The re-designed Galvashield® XP Product Line incorporates the contractor-friendly One-and-Done™ single-wire connection for up to 2x times faster installation. Plus, the new low profile, elongated shape allows the embedded anode to fit neatly alongside the reinforcing steel thus reducing the occasional need for additional concrete breakout to accommodate anode placement.
These features mean significantly less labor costs and more efficiency for the contractor’s schedule. The new shape also allows more anodes per box thus reducing shipping costs.
The Galvashield® XP4 and XP2 models have additional benefits, such as the Barfit™ grooved design for secure anode placement and CSP-3 surface profile to promote enhanced mechanical bond with the surrounding repair materials.
Galvashield® N
Galvashield N embedded galvanic anode units are used in new concrete construction to provide corrosion prevention to reinforcing steel. These alkali-activated (Type 1A) anodes are comprised of high-purity zinc cast around a steel tie wire with an enhanced formulated cement-based mortar with an internal pH of 14 or greater that keeps the zinc active over the life of the anode.
Galvashield N anodes are quickly and easily installed using extra long tie wires in the center of the reinforcing grid before new concrete is placed to ensure even current distribution to all steel. Once installed and embedded in the new concrete, the zinc anode corrodes preferentially to protect the adjacent reinforcing steel. For anode system design details, refer to the technical data sheet.

Features and Benefits
- Proven technology: Galvashield is the original embedded galvanic anode with over a 20-year track record.
- Long lasting: direct protection provided during the 10 to 20 years anode life. Extended corrosion mitigation is provided after anode consumption due to positive electrochemical benefits.
- Type 1A anode: alkali-activated to maintain activity of zinc; meets building code requirements that prohibit intentionally added constituents that are corrosive to reinforcement within repair area.
- 2G Technology™: provides enhanced current output and protection.
- Cast zinc core: provides high anode utilization in addition to secure long term connection between the zinc and the lead wires.
- Integral steel lead wires: allows for quick and convenient anode installation. Provides dependable steel-to-steel contact with no intermediate materials such as galvanizing that may compromise the long-term electrical connection. Extra-long lead wires allow the anode to be tied in the center of the reinforcing grid to provide more even current distribution.
- Versatile: can be used for both conventionally reinforced and prestressed or post-tensioned concrete.
- Low maintenance: requires no external power source or system monitoring.
Anode Type
