WHO WE ARE

Casting Since
1948

Protea Foundry was established in the late 1940s as a brass and bronze foundry serving Cape Town's ship repair industry. Over four generations we've grown into one of the southern hemisphere's specialist suppliers of sacrificial anodes. Today our anodes protect everything from offshore platforms in the Atlantic and Indian oceans, to the harbour walls of Cape Town, Durban, Walvis Bay and beyond. Every casting carries the same promise it did 78 years ago:

poured properly, certified honestly and shipped on time.
