Last year South Africa’s state-owned Industrial Development Corporation (IDC) announced that the restructuring of its steel subsidiary Scaw Metals into three standalone entities was at an advanced stage, as were plans to secure strategic equity partners (SEPs) for each of the units.

Earlier this year it was announced that the IDC had reached an agreement with Barnes Southern Palace (BSP) to buy into Scaw’s rolled products and wire rod products businesses, which employ more than half of Scaw’s 3 500 workforce.

Shortly thereafter the Competition Commission approved the proposed merger, without conditions, whereby Magotteaux International SA (Magotteaux) intended to acquire an interest in and acquire management control in Grinding Media South Africa (Pty) Ltd (GM Newco), which was formerly the grinding media business division of Scaw Metals South Africa.

Cast Products South Africa has been a long time partner with Amsted Rail, a global leader in freight wagon components, manufacturing under license cast monoblock railway wheels for the local railway market

This latest development has been submitted to the Competition Commission and is awaiting approval. The Cast Products division has been a long time partner with Amsted Rail, a global leader in freight wagon components, manufacturing under license cast monoblock railway wheels for the local railway market. Cast Products South Africa produces railway wheels using modern curved plate design, which ensures lower operating stress to improve fatigue life. All wheels are produced in AAR M108 Grade C material, which gives excellent wear properties, according to the company. The wheel products include 34” cast wheels for general freight operations (22 ton axle load) and 36” cast wheels for heavy haul operations (32.5 ton axle load) typically found on the coal and iron ore lines.

Cast Products South Africa’s wheel plant manufactures an average of 3 200 wheels in a month with the average weight of 380 kilograms per wheel. Transnet SOC, South Africa’s state-owned freight transport and handling company, is one of Cast Products South Africa’s larger customers.

Amsted Rail manufactures and markets heavy-haul equipment worldwide. The company offers “Adapter Plus” steering pad systems, axles, bearings, brakes, centre plates, coil springs, couplers, connectors, knuckles, drawbars, cushioning units, draft sills and draft gears, friction shoes, hatch covers, plastic pellet gates, “Preload Plus Constant Contact Side Bearing”, truck assemblies, wear prevention products, and wheels. It also provides IONX, an asset monitoring solution that tracks fleet from anywhere in the world. The company was incorporated in 1977 and is based in Chicago, Illinois, USA.
