Sectional door， an electrically operated roller door used in industrial and commercial premises. This type of door is designed to allow the door to be lifted quickly on a track, thus saving space and improving access efficiency. Liftgate usually consists of door panels, guide rails, drive systems, control systems and other major components.

The door panel is usually made of high-strength steel plate, and the surface may be treated with anti-corrosion treatment or painted decoration. The inside of the door plate may be filled with thermal insulation material to provide good thermal insulation. The ends of the door are fitted with guide rails, which are fixed to the walls of the door opening, and the door panel rises or falls along the rails.

The drive system, which usually consists of an electric motor and reduction gear, is responsible for driving the door panels up and down. The control system, on the other hand, is responsible for starting, stopping and regulating the movement of the door, and may include both manual and automatic control.

The sectional door has the following features:

1. Space-saving: Because the door body is vertical movement when lifting, it will not occupy the floor space of the doorway, which is suitable for installation in areas with restricted space.

2. Rapid opening and closing: the sectional door can be opened and closed quickly, which greatly improves the efficiency of entering and exiting, and is suitable for occasions that require frequent opening and closing of the door.

3. Safety performance: Sectional door is usually equipped with a variety of safety devices, such as infrared sensors, ground sensing strips, etc., to prevent people or objects from being pinched during the movement of the door body.

4. Sound insulation and dust insulation: The door body has good sealing performance, which can effectively isolate external noise and dust and keep the internal environment clean.

5. Durability: The design and material selection of the sectional door make it highly durable and able to adapt to various harsh working environments.

Sectional doors are widely used in industrial plants, warehouses, logistics centres, workshops and other places, and are important facilities for improving work efficiency and ensuring safety.
