The process of continuous casting involves molten metal being poured continuously through a water-cooled mold. The casting is cooled, removed by rollers, then cut to the desired length with a traveling saw. A continuous casting can be done either horizontally or vertically. Using a gravity-fed bottom-flow method prevents dirt and impurities from affecting the casting. Combining the use of low heat casting temperatures and the water-cooled mold allows for a homogenous and high-density product.

Continuous cast solid and hollow bars can have an outside diameter of up to 610 millimetres. Different inside diameters are achieved by using a variety of cores inside the molds. Often times these long bars are sliced into smaller pieces, but can also be used in their original form.
