• Very high producing rate

• Professional team & exquisite workmanship

• Considerable after sale service

• Excellent dimension rate

• Very competitive price

Application

Various types of highway and railway bridges: can significantly reduce the horizontal force transmitted to the bridge piers and upper structures during earthquakes, protecting the main structure. For example, when improving the seismic performance of continuous beam bridges, replacing traditional pot type rubber bearings with FPS bearings is a proven and effective solution

Important public buildings and lifeline projects: widely used in schools, kindergartens, hospitals, emergency command centers, and other buildings with extremely high seismic requirements to ensure their functionality is maintained after a disaster

Nuclear power plant equipment isolation: Nuclear power plants have extremely high requirements for safety. Research and experiments have shown that FPS systems can effectively isolate the seismic response of key equipment inside nuclear power plants, improving their safety and reliability under extreme earthquakes.

Large storage tanks and industrial facilities: can be used for base isolation of structures such as large oil storage tanks and important industrial plants to prevent secondary disasters caused by earthquakes

Features

Excellent stability and durability: It is mainly composed of metal and polymer friction materials, and its performance is much less affected by time and temperature than traditional rubber bearings, thus having a longer service life and more stable hysteresis performance. Experiments have shown that even if the friction plate experiences wear, its impact on the friction coefficient of the sliding interface is limited, and it can maintain stable energy dissipation capacity.

Reliable self resetting capability: The support utilizes the gravity of the structure itself as a restoring force. After the earthquake, it can automatically return to the center position like a pendulum, without the need for additional reset devices.

Flexible and controllable design parameters: Engineers can control the vibration period of the structure by adjusting the radius of the slide according to their needs, and control damping (energy dissipation capacity) by selecting different friction materials. Moreover, its vibration period is independent of the mass it carries, which brings great convenience to the design.

Strong deformation adaptability: Its sliding surface design allows the support to generate significant bidirectional displacement in the horizontal direction (common design displacement can reach ± 250mm to ± 500mm), and the structure will not be damaged under large deformation. After the earthquake, it usually does not need to be replaced
