Double-leaf gate
Double-leaf gates consist of two separate leaves that open and close independently of each other. Double-leaf gates have several advantages and disadvantages compared to other types of gates. Advantages include, for example, the possibility to open only one leaf for pedestrian access, easy installation and maintenance, aesthetic appearance, and a wide range of materials and designs. Disadvantages include, for example, the need for sufficient space to open both leaves, lower security and thermal insulation compared to sliding or sectional gates, and higher susceptibility to damage from wind or force. Double-leaf gates should be appropriately chosen according to the needs and possibilities of the user and installed on a stable and level surface.
Advantages and characteristics of double-leaf gates:
- Size and opening,
- Materials, construction, and sealing,
- Safety features and control,
- Maintenance.
Size and opening
Double-leaf gates can be designed in various sizes according to the needs of the prefabricated hall and the use of vehicles or machinery. It is important to choose gates that are sufficiently wide and high. Double-leaf gates open by swinging each leaf to the side. This opening method allows the entire entrance opening to be used, which is important for large and bulky loads.
Materials, construction, and sealing
Depending on requirements, double-leaf gates can be made from various materials such as steel or aluminum, but most commonly they are made from standard PIR sandwich panels. The materials are resistant to external influences and at the same time lightweight for easy opening. High-quality sealing around the perimeter of the gate is important to minimize air, dust, and weather penetration. This is especially important if the prefabricated hall is used for storing or manufacturing sensitive materials. Double-leaf gates can be designed with regard to the aesthetic appearance and design of the prefabricated hall. This may include various surface finishes and colors.
Safety features and control
Double-leaf gates should include safety features such as stoppers to prevent unintentional closing. In exceptional cases, they are designed with safety features such as sensors for obstacle detection, which stop the movement of the gate if it encounters an object or person. The gates can be operated manually or automatically. Modern automatic systems allow remote control, key switches, or even integration into building automation systems.
Maintenance
Regular maintenance is important to keep double-leaf gates functioning properly. Mechanisms should be checked, joints lubricated, and worn parts replaced.
Double-leaf gates for prefabricated halls are a practical and cost-effective solution for entrances that require sufficient space for handling loads. It is important to choose the appropriate type of gate in accordance with the requirements and operational needs of the prefabricated hall.
