2. If the deformation is serious, it is best to replace the door and door cover again, so as not to affect the later use.
As we all know, the aluminum alloy door is the most fragile of all materials, so the action must be light when using it, and the push and pull should be natural. If there is a jam, don't push hard, be sure to troubleshoot first. Dust accumulation and deformation are the main reasons for the failure of aluminum alloy doors, so to keep the door frame clean, you can use a vacuum cleaner to remove orange dust from the grooves and door seals.
In daily use, always check the joints of the frame, tighten the bolts and replace the damaged parts.
