1. Strong Fire Resistance

Special Materials

Fireproof hinges are made from special, high-temperature-resistant metals or alloys. These materials are extremely stable in high-temperature environments and can withstand the intense heat of a fire. For example, some fireproof hinges utilize specially treated stainless steel, which has a melting point much higher than that of ordinary steel. Even under prolonged flames, they resist deformation and melting.

Fireproof Duration

Designed and tested according to strict fire protection standards, fireproof hinges maintain their connection and rotational function for the specified time. This critical feature ensures the proper operation of fire-resistant doors and windows during fires. For example, even after fire tests lasting several hours, they remain able to close and open, effectively preventing the spread of fire.

2. Structural and Functional Features

Sturdy Structure

The structural design is exceptionally sophisticated and robust. Its well-designed mechanical structure can withstand the weight of the door or window while ensuring stability during both daily use and fire emergencies. Tight connections between components reduce the risk of loosening or separation in high temperatures.

Smooth Rotation

Fireproof hinges offer smooth rotation while maintaining fireproof performance. Whether it's frequent daily opening and closing operations or adjustments during a fire, they can be easily performed. This allows fire doors and windows to be quickly closed and opened, facilitating evacuation and fire rescue efforts.

3. Applicability and Maintenance

Wide Applicability

Fireproof hinges are suitable for all types of fire doors and windows, including those made of wood, steel, and other materials. They can be used in fire-resistant installations in residential, commercial, and industrial buildings.

Easy Maintenance

Maintenance costs are low, requiring only regular inspection of the hinge joints for looseness and corrosion, as well as simple cleaning and lubrication. This low maintenance requirement makes fireproof hinges highly practical in building fire protection systems.

With their excellent fireproof performance, stable structure, excellent applicability, and easy maintenance, fireproof hinges have become an indispensable component of building fire safety.
