The five-step hot extrusion process consists of preparation, cutting, heating, extrusion and finishing.
The starting stock consists of solid round bars. These are peeled to remove imperfections in the surface. The bars are then cut into the required extruded lengths based on a profile weight-to-area ratio.
These bars are then passed through induction furnaces. The controlled atmosphere heats the product to a temperature required for the steel. They are extruded in a horizontal hydraulic press, then straightened, punch straightened and detwisted to their final dimensions.
The hot extrusion bars produced by the company are made to certain specifications. For example, metal bars for use in structural applications have a T profile in standard stainless steel and lengths from four to seven metres.
Other extrusion bars it produces have equal Angle L, Z, U, and H profiles. It also produces seamless fin tubes, hexagonal profiles, omega tubes and double omega tubes.
