Industry application
Magnesium Sacrificial Anodes for Cathodic Protection
Magnesium sacrificial anodes corrode in place of the steel they protect. SGZ casts and extrudes them in round and cube form, with holes or threads where the mounting calls for them, for vessels, ports and ocean projects, buried cables and pipework, and water heating equipment.
Industry pain points
What Goes Wrong in This Industry
Steel corroding where the coating has failed
An anode corrodes instead of the structure, which is far cheaper than replacing the steel.
Anodes that do not match the mounting
SGZ produces round or cube anodes, with holes or a thread, or to a customer request.
One production route that does not suit the quantity
SGZ offers both casting and extrusion.
Damage in transit
Anodes are packed in wood cases, or as the customer requires.

Delivery capability
What SGZ Can Actually Supply
- Production routesCast or extruded.
- FormsRound, cube, with holes optional, with thread optional, or as requested.
- PackingWood case, or as requested.
- Other magnesiumTooling plate, vibration testing plate and magnesium alloy profiles from the same programme.
Plate, chemistry, machines and packing all come from the same supplier, which is what keeps the etch result repeatable across a programme.
