Aluminium can be seen as a new material in the construction field such as in buildings and bridges. In manufacturing, extrusion is the common method, while roll-forming is the new method to make cold-formed aluminium sections including channel and Zed sections; and it has illustrated its effectiveness compared to the extrusion. There are not any standards on cold-formed aluminium structures worldwide, these current standards were historically calibrated and applied for the extruded aluminium sections. Currently, research studies on cold-rolled structures have been progressively conducted to make available data from experiments and numerical studies, which are the base for modifications and recommendations in the design of this structural type. The paper, therefore, will apply the European Aluminium Code in determining the strengths of cold-formed aluminium channel columns; subsequently, these predicted capacities are compared with the collected experimental and numerical strengths. These comparisons are conducted by using reliability analysis with the application of the probability-based load and resistance factor design method according to the American Specification. Based on these comparisons, recommendations are provided for the applicability of the European Aluminium Code for designing of such aluminium channel columns. It was found that the European Code provides quite good predictions for the strengths of such columns although these are quite low efficiency.
