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.

DSI South Africa employs about 120 people and produces on average 300,000 completed roof bolt 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. The group’s entry into mining products came in 2001. DSI employs 1700 people worldwide.
