Extrusion

Steel

Extrusion is the method of producing lengths of steel to a particular shape by forcing the metal through a die cut to the cross-sectional shape required. The method is used to produce a wide range of shapes, from rounds, squares, “L” shapes, “T” shapes and tube, through to complex sections that can be difficult to make by any other method. The method is also widely used for non-ferrous metals, particularly aluminium, as well as plastics.
