You said that the rolling shutter door is protruding. Does that mean that the rolling shutter door is deformed? Generally speaking, if the deformation of the rolling shutter door does not affect its use, you can not rush to restore it to its original state. If the functionality is affected, you will have to ask the manufacturer for repairs. If the rolling shutter door is deformed, it is not recommended that you reshape it yourself. It is a difficult task.
