A Double-Leaf Fire-Rated Door refers to a dual-panel fire door—typically comprising one wider main leaf and one narrower auxiliary leaf—suited for building entrances that require a greater passage width, a higher level of security, and enhanced spatial adaptability. The core value of a fire-rated door lies in its ability to form a complete protective unit—integrating the door leaves, frame, hardware, sealing mechanisms, and closing systems—to retard the spread of fire in the event of an outbreak, thereby gaining critical time for occupant evacuation and emergency response within the building. In modern architectural projects, such doors not only fulfill the fundamental requirements for safety egress but also significantly influence the entrance's visual aesthetics, daily operational comfort, and long-term maintenance costs. The ARTY model, featuring an asymmetrical double-leaf design, is ideally suited for projects with exacting standards regarding door opening dimensions, facade proportions, and decorative styles.

1. Retro Style

This Double Leaf Fire-Rated Door features a color palette combining antique red bronze and antique yellow bronze, presenting a sophisticated metallic texture on its surface. The three-dimensional vertical brass accents positioned in the center enhance the visual depth and layering of the door face, making it an ideal choice for high-end entryway designs in modern residences. The standard dimensions of 2050 x 1160 mm are compatible with common residential door openings, though custom sizing is also available to suit specific project requirements.

2. Substantial Construction

The door leaf features a thickness of 80–100 mm, offering a structural advantage over standard interior metal doors. This design enhances the door's stability, provides a greater sense of separation, and extends its service life. The steel door face is resistant to deformation even after prolonged and frequent opening and closing, making it ideal for high-traffic areas. This Double-Leaf Fire-Rated Door effectively meets the fundamental requirements for safety and durability in residential apartment settings.

3. Stability

The product features a visible, exposed-hinge structure; once installed, the load-bearing points are clearly identifiable, facilitating subsequent inspection and maintenance. The asymmetrical double-leaf design allows for the primary door leaf to be opened for daily passage, while the secondary leaf is opened only when transporting large items. The inward-opening mechanism is compatible with the layouts of most residential entrances, thereby minimizing encroachment upon external public walkways.

4. Security

The door unit is equipped with a mechanical locking system characterized by a straightforward structure and reliable operation, making it ideally suited for residential homes, apartments, and modern dwellings—specifically for entrance locations where long-term reliability is a critical requirement. For fire-rated applications, the door must be installed in conjunction with a compatible frame, seals, and hardware to ensure a fully integrated and effective assembly; during project procurement, appropriate specifications should be selected in accordance with the specific fire compartmentation requirements of the building.

5. Practicality

The product is equipped with a door closer and a vision panel. The door closer facilitates the automatic return of the door leaf to its closed position, thereby mitigating safety risks associated with doors left ajar. The integrated vision panel enhances visibility between the interior and exterior, making it easier to assess conditions for safe passage—particularly in residential corridors and apartment floor entrances—and effectively balancing functional utility with a modern aesthetic.

1. Apartment Residences

The Double Leaf Fire-Rated Door is ideal for the entryways of apartment residences. Its double-leaf structure increases the passage width, facilitating the easy movement of furniture, appliances, and renovation materials. The choice of antique red bronze or antique yellow bronze finishes enhances the visual distinctiveness of the home's facade, lending the entrance a heightened sense of decorative elegance.

2. Modern Homes

In modern residential settings, this door serves perfectly as a main entrance door. Its three-dimensional vertical brass accents harmonize beautifully with other spatial elements—such as stone, wood veneers, and metal trim—transforming the door from a mere security component into an integral part of the overall facade design.

3. Floor Corridors

The Double Leaf Fire-Rated Door is well-suited for use in apartment floor corridors or connecting areas within communal hallways. Its asymmetrical double-leaf configuration facilitates convenient daily pedestrian traffic; for the transport of bulky items or during maintenance operations, the secondary leaf can be opened to expand the passage space, thereby enhancing the operational efficiency of the floor.

4. High-End Projects

For luxury residences, model homes, and apartment renovation projects, this door satisfies both aesthetic requirements regarding facade texture and functional specifications. Featuring a steel-plate face, a substantial leaf thickness of 80–100 mm, a mechanical locking system, and an integrated door closer, it is an ideal choice for project procurement teams prioritizing reliable delivery and robust performance.

5. Zonal Entrances

The Double Leaf Fire-Rated Door is also suitable for marking key zonal entrances within a building's interior, helping to establish clear spatial boundaries. The inclusion of a vision panel allows for easy observation of conditions on the other side, while the door closer ensures the door remains securely shut—making it an excellent solution for locations where strict security management and orderly traffic flow are required.

Daily cleaning:

Use a soft dry or slightly damp cloth to wipe the surface of the Double Leaf Fire Rated Door. Avoid using detergents containing corrosive chemicals to avoid damaging the surface coating. The door frame and hardware should also be cleaned regularly to ensure that there is no dust and stains accumulated on the surface to maintain the overall appearance and good working condition of the door.

Check the door closer:

Check the operation of the Double Leaf Fire Rated Door door closer regularly to ensure that it can work properly. Check whether the mounting bolts of the door closer are loose. If they are loose, tighten them in time. At the same time, check whether the oil level of the door closer is sufficient. If necessary, add special lubricating oil according to the requirements of the product manual to ensure the service life and performance of the door closer.

Check the lock:

Check the flexibility and reliability of the Double Leaf Fire Rated Door lock regularly to ensure that the lock tongue can be retracted and retracted normally and the lock core rotates smoothly. If the lock is found to be stuck or difficult to open, add an appropriate amount of lubricating oil in time, or contact a professional for repair. At the same time, check whether the lock is installed firmly regularly to prevent the normal use of the lock from being affected by looseness.

Check the door frame and hardware:

Check whether the Double Leaf Fire Rated Door door frame is firmly installed and whether it is loose or deformed. For hardware, such as hinges and handles, check whether they are loose or damaged. If there is a problem, replace or repair it in time. Lubricate and maintain the hardware regularly to extend its service life and ensure the normal opening and closing of the door.

Check the fire seal:

The fire seal is an important fireproof component of the Double Leaf Fire Rated Door. Check it regularly to see if it is intact. If the seal is found to be aging, deformed or falling off, replace it with a new one in time to ensure the fireproof performance of the door. At the same time, when installing the seal, ensure that it fits tightly with the door frame and door leaf without any gap.

Check the overall structure regularly:

Check the overall structure of the Double Leaf Fire Rated Door regularly, including the door leaf, door frame, filling material, etc. Check whether the door leaf is deformed or damaged, whether the door frame is firm, and whether the filling material is loose. If any problems are found, they should be repaired or replaced in time to ensure the fire resistance and overall stability of the door, providing reliable protection for the safety of the building.
