During our long, proud history, we have received recognition as one of South Africa’s most trusted suppliers of custom metal castings for use in paper production applications as well as chemical pulp refining processes.

Steloy provides a wide range of cast steel products for valves, pump components, refiner discs, wear rings and housings, most of which are supplied in CF8M or 17.4PH. Our advanced technical capabilities and state-of-the art facilities allows us to deliver cast components on-time and in accordance with our clients’ quality requirements and international standards.
