BaiQi aluminum anodes are designed to safeguard metal structures against corrosion in seawater and brackish water environments. We provide an extensive selection of half-shell and segmented aluminum bracelet anodes, available in both welded and bolted configurations. Composed of multiple individual anode sections, these bracelet anodes are ideally suited for direct circumferential mounting around cylindrical structures.
