There are different options to bending aluminum extrusions. Each option has advantages and disadvantages as well as its challenges.  That’s why you have to evaluate deeply both options and see which one suits your needs.
Manual bending of aluminum extrusion requires a lot of energy. Keep in mind extruded aluminum is very strong and bending may not be easy. To achieve this, you should use aa strong bender that will move the metal into shapes that you want.
This can be done with the support of human labor. That means you will incur more in terms of overhead costs. The good thing about this is the fact that you can create unique shapes that some machines cannot. The only downside is the fact that it may take time before completing a project.
