When producing folding doors, we will debug and test before leaving the factory, and then install all frames, door panels and hardware. After the commissioning is completed and the test is passed, the door frame and the door panel are separated, and then packaged. Therefore, when the product is received, the installation work is very simple, just fix the frame, connect the door hinge, install the hand and sealant. But the French door is too heavy and requires three people to complete it. Two people hold it, and one repairs it. In addition to the large panels, the factory also installed glass and hardware. Installation is not complicated, but it needs to be lifted and moved. In addition, in large-scale projects, we also have professional installation technicians who can help you.
