Production milestone for roofbolt manufacturer

The South African subsidiary of German multinational company DYWIDAG-Systems International (DSI), celebrated its fourth anniversary in September with the production of its 12-millionth roofbolt at its Elandsfontein operation. DSI South Africa manufactures strata support products for the coal, gold, platinum and diamond-mining industries.

The milestone was recently commemorated with the presentation of a bronzed and mounted replica of the roof bolt to the company’s shareholders DSI GmbH and construction company WBHO. The company, an employer of around 120 people, produces on average 300,000 completed roofbolt assemblies a month. Its black economic-empowerment division DSI-Mandirk Strata Support, established in 2003 also produces a wide array of strata support products including grouting rods, shepherds crooks and forged head bolts.
