Aluminum bifold patio doors
large size design
Aluminum bifold patio doors are a type of patio door made from lightweight, durable aluminum frames that are designed to fold in a concertina style, allowing them to be opened and closed quickly and easily. These doors typically consist of multiple panels that are connected by hinges, and when opened, they fold up and stack against the wall to create an unobstructed opening between the interior and exterior spaces.
