The Galvashield XP anodes are used to provide corrosion protection to both concrete repair and new concrete construction. Anode units are alkali-activated to keep the zinc active over the life of the anode while being non-corrosive to reinforcing steel. The BarFit design incorporates grooved edges on the anode units to assist with secure anode placement. The product can be used for both conventionally reinforced and prestressed or post-tensioned concrete. Vector Corrosion Technologies. 813-830-7566.
