Steel Double Doors
For public buildings, the installed double doors should be sturdy and durable. Since they are installed in public buildings with a large flow of people, they need to have high strength and stability, be able to withstand heavy traffic and frequent use, and be resistant to deformation and damage. They are suitable for places with frequent personnel access in public buildings, such as the main entrances and exits of schools, hospitals, and shopping malls. Secondly, for such public buildings, high safety is also required. The material is solid, with good anti-theft and fireproof properties, which can provide more reliable safety protection for public buildings. They are often used in places with high safety requirements, such as banks and museums. In addition, they should have diverse appearances. Because different public buildings have different styles and designs, the double doors should be designed according to the local architectural style. Through surface treatment and spraying processes, various colors and textures can be achieved, such as the common silver and gray, which can match different styles of public buildings. At the same time, the aesthetic and transparency can be enhanced by adding glass windows and other means.
Aluminum Alloy Double Doors
Regarding the exterior design of double doors, they should be lightweight and aesthetically pleasing. Doors and windows, as decorations, should look good and give people a pleasant visual experience. Also, the double doors are relatively light in weight, easy to open and close, and have good corrosion resistance and decorative properties. Their surfaces can be treated by anodizing, electrophoretic coating, etc., presenting different colors and luster, such as gold and champagne, adding a modern and fashionable feel to public buildings. They are often used in places like hotels and office buildings. They are energy-efficient and environmentally friendly. The thermal conductivity of aluminum alloy is low, with good heat insulation performance, which helps reduce the energy consumption of buildings, meeting the requirements of modern public buildings for energy conservation and environmental protection. The maintenance cost is low. They are not prone to rusting or fading, have a long service life, and only require simple cleaning for daily maintenance, without the need for regular painting and other maintenance work, saving maintenance costs and time. The design of double doors should be user-friendly, and the design and use in different occasions should conform to the nature of the occasion itself. For example, when designing the first floor of a high-rise office building, the double doors should be simple and elegant, mainly with a simple and bright design, fitting the commercial office environment. Another example is that if it is in a high-end entertainment venue, more stylish and brighter double doors can be installed to match the positioning of the high-end entertainment venue. For different occasions, different double doors should be designed according to the specific occasion to create double doors that are in line with the current place.
Glass Double Doors
As the name implies, glass double doors have the characteristics of being transparent and bright, with excellent light transmittance, enabling the indoor and outdoor spaces to be mutually transparent, increasing the sense of openness and brightness of the space. They are suitable for public building places that need to create a spacious and bright atmosphere, such as the hall entrances of exhibition halls and libraries. They have good visual effects. Various types of glass can be used, such as clear glass, frosted glass, and colored glass, which can be integrated with different architectural styles and decorative themes to create unique visual effects and enhance the overall aesthetics of the building. Transparent glass has relatively good light transmittance, which can make the indoor environment brighter and more comfortable, improving the quality of life. The safety performance has been enhanced. Modern glass double doors usually adopt tempered glass or laminated glass and other safety glasses, which have high strength and impact resistance. Even if the glass breaks, it will not produce sharp fragments, reducing the risk of injury to people and ensuring public safety.
Fireproof Double Doors
In general, important restaurants, theaters, stadiums and other large venues all require relatively strong fireproof performance. Double doors can meet this requirement. Excellent fireproof performance is of great importance in public places. In public buildings, fire safety is crucial. Fireproof double doors adopt special fireproof materials and structural designs, which can prevent the spread of fire within a certain period of time, buying time for personnel evacuation and fire rescue. They are commonly seen in the evacuation passages and between fire compartments of crowded public places such as shopping malls, theaters, and hospitals. They comply with fire protection regulations, are strictly designed, produced, and installed in accordance with relevant national fire protection standards and regulations, and have clear fireproof grade markings, such as Class A and Class B, which can meet the fireproof performance requirements of different places and ensure the safety of public buildings in the event of a fire.
Thermal Insulation Double Doors
The characteristic of these thermal insulation double doors is that they have a good energy-saving effect. For some public buildings with high requirements for indoor temperature control, such as office buildings and hotels, thermal insulation double doors can effectively reduce heat transfer, reduce the energy consumption of air conditioners or heaters, and achieve the goals of energy conservation and emission reduction. Another characteristic of these double doors is that they can provide a comfortable using environment. By using thermal insulation materials and sealing structures, they can effectively block the entry of cold and hot air from the outside into the indoor, keeping the indoor temperature stable, creating a comfortable indoor environment for users and improving the quality of use of public buildings.
Soundproof Double Doors
The most prominent feature of soundproof double doors is sound insulation and noise reduction. They can effectively reduce noise. In some public building places that need to maintain a quiet environment, such as conference rooms, concert halls, and libraries, soundproof double doors can effectively block the interference of external noise, providing a relatively quiet space indoors, ensuring the normal progress of activities such as meetings, performances, and studies. They can also improve the acoustic effect. Their special soundproof structures and materials can absorb and reflect sound waves, improving the acoustic effect indoors, enhancing the clarity and quality of sound, and strengthening people’s auditory experience indoors.
Sliding Double Doors
For sliding double doors, their characteristic is that they are convenient and fast to open. The opening method of sliding double doors is simple and direct. They can be opened with just a gentle push, which is convenient and fast, suitable for places with rapid personnel access, such as the entrances and exits of subway stations and railway stations. They can effectively improve the personnel passing efficiency. These doors can also save space. When opening, the door body moves parallel to the wall surface, without the need to reserve a large opening space. They are more suitable for the entrances or passages of public buildings with limited space, enabling full utilization of the limited space and improving the space utilization rate.
Rotating Double Doors
Rotating doors have strong passing capacity and are suitable for being installed in hotels. Rotating double doors can accommodate multiple people entering and exiting simultaneously, with a large passing capacity, suitable for public buildings with large and concentrated personnel flows, such as large shopping malls and hotel lobbies. They can effectively guide the flow of people and avoid congestion. Another characteristic of these doors is that they are aesthetically pleasing and magnificent. With their unique rotating opening method, they have an elegant and magnificent appearance, often used as the iconic entrance of public buildings, which can enhance the overall grade and image of the building and leave a deep impression on people.
