Lift-and-turn gates are a structure in which the door leaf opens and closes due to movement along special guides. Due to this, it changes its position from vertical to horizontal, located under the ceiling of the room (usually a garage). The lifting process takes place thanks to the corresponding levers and springs. The frame of the structure is mounted, as a rule, from rectangular pipes. The absence of numerous articulated joints makes the scheme simpler than roll and sectional varieties. In this regard, overhead-swing gates are characterized by high reliability, relative efficiency and ease of operation.
Canvas structure
The canvas of the structure consists of a frame and its lining. The frame is made by welding rectangular shaped iron profiles. As for the cladding, then its role may be wood or metal. It should be noted that the second of the listed materials in our conditions is much more expedient to use. In addition, it is desirable that the panel mounted on a pivoting gate be galvanized. Now the choice of the buyer presents options decorated with panels, cassettes, corrugations. In addition, completely smooth and even mirror surfaces, which are decorated with all kinds of inserts, are often used for cladding. An interesting nuance is the fact that the insulation of the fabric in the factory is not performed. If desired, the user can do this on his own, using various materials.
Gate management
The simplest and most common mechanism for a pivot gate is manual. The fact is that it is included in the standard configuration, therefore it does not require significant financial investments. Optionally, you can purchase an electric motor that will allow you to start the closing and opening process using the remote control directly from the passenger compartment or with a button in the garage.
Installation
In most cases, up-and-over gates are supplied by the manufacturer in assembled form and in combination with anchors and other fasteners. The frame during installation is mounted behind the opening or directly in it. It is very important that at the time of installation of the structure in the garage, absolutely all work related to the floor and the opening should be completed. It should be noted that the gate can be mounted both with a restrictive bar below and without it.
Security, Limitations and Cost
Far from the last important parameter for the gate is their safety. In this regard, the solutions that are provided in modern models allow you to protect the garage from breaking, exclude the slightest likelihood of the canvas falling, and also prevent pinching of fingers or foreign objects. The main limitation of the design is the possibility of its use exclusively in rectangular openings. About their use for arched or segmented forms of arrival is out of the question. In addition, it should be borne in mind that when opened, the canvas extends outward by a distance of about one meter. Unlike the sectional view of the door, the canvas is a one-piece construction, so it is impossible to repair a separate part of it in case of breakage. As for the cost, for a design such as a garage door (lift-and-rotate), the price depends on the parameters listed above and ranges from 50 to 75 thousand rubles.
