The Vaal Triangle is a triangular area formed by Vereeniging, Vanderbijlpark and Sasolburg about 60 km south of Johannesburg, South Africa.[1] The area forms a substantial urban complex. Meyerton, just north of Vereeniging, is also sometimes included in the complex,[2] and residents of Sharpeville, Boipatong, Bophelong, the greater Sebokeng area (including Evaton), Three Rivers, Heidelberg and Deneysville also generally tend to consider themselves to live in the Vaal Triangle.[citation needed] The area straddles the Vaal River and is a major industrial region, which is home to former Iron and Steel Corporation Iscor, now ArcelorMittal South Africa, and Sasol, respectively the steel and petrochemical processing facilities.[3][4]
