What’s the difference between aluminium extrusion and fabrication?

Not everyone’s an expert in all things extrusion and fabrication, and we pride ourselves on being accessible to customers with varying levels of technical knowledge. This is one of the questions we get asked sometimes, and the answer is pretty simple. Aluminium extrusion is the process of forcing an aluminium billet through a die in order to change its profile (into a tube, or a bar, or an H-profile – there are almost endless possibilities). Aluminium extrusion fabrication is the fabrication of these extruded aluminium profiles. So, we might take an extruded aluminium sheet and then punch some holes in it. That’s fabrication. Or we might weld it: that’s fabrication, too. Aluminium extrusion fabrication just means working on the extruded profile – simple!
