How do I know if my current building uses aluminum profiles or not?

To determine if your current building uses aluminum profiles, you can start by examining the visible structural components such as window frames, door frames, and support beams. Look for the characteristic silvery color and smooth finish of aluminum. You can also check the building's documentation or blueprints, if available, for material specifications. Consulting with the building's architect or engineer can provide definitive information. In some cases, a non-destructive testing method like ultrasonic testing might be used to identify materials without damaging the structure.
