Magnesium Ribbon
Magnesium ribbon consists of an extruded ribbon of magnesium around a central galvanised steel core which ensures a uniform current and efficient electrical discharge.
Magnesium ribbon offers one of the highest potentials of all sacrificial anodes and is used to protect buried and immersed steel structures.
Magnesium ribbon is particularly suited to areas of restricted space

Benefits of magnesium ribbon:
- Uniform current distribution over the ribbon anode length
- Uniform anode consumption
- Provides a large surface area and therefore a high current output
- Easy to handle, ship and install
