Vereeniging was richly endowed to become a future industrial town. Not only were coal and water in plentiful supply in the vicinity, but there was also glacial conglomerate to provide fire-clay, dolomite for calcium and lime, black reef to supply silica, and excellent quarry stone for building purposes. The railway also provided a vital transport link from the south to the gold mines of Johannesburg.

Vereeniging was, after World War II, to develop into one of the busiest manufacturing areas in the country. The establishment of Iscor and the building of Sasol, would see many heavy engineering firms appearing in Vereeniging. Specialised services and other manufacturing operations soon sprang up to process raw steel output into crafted finished products. Foundries, machinery, cables, chains, steel tubing, wire, farm implements, refractory bricks and ceramics were just a few of the products produced by a host of manufacturers.
