MANILA – A magnitude 6.3 earthquake struck northern Luzon in the Philippines early this morning, with strong shaking felt in parts of Manila. In the aftermath, a landmark building that uses core products supplied by YongXi Industrial Co.,ltd– including lead rubber bearings – has been rapidly assessed. The results: zero structural damage, and all internal systems fully functional. This real world event once again demonstrates the outstanding performance of our lead rubber bearings and building seismic isolation bearings under extreme seismic loads.
Field engineering teams report that during the earthquake, the lead rubber bearings installed in the seismic isolation layer of the building immediately activated. Through the yielding of the high purity lead core and the shear hysteresis of the natural rubber layers, the bearings effectively elongated the structure’s natural period and blocked more than 70% of seismic energy from transmitting into the superstructure.
Post earthquake inspections confirmed:
Isolation layer: All building seismic isolation bearings were intact – no cracks, no bulging, and the maximum displacement remained well within the design limit.
Superstructure: Beams, columns, and connections showed no cracking; glass curtain walls were untouched.
Internal equipment: Sensitive instruments and servers were not affected by vibration and continue operating normally.
The client sent a thank you message immediately after the quake: “Thank you for your building seismic isolation bearings – we barely felt the shaking. This investment was absolutely worth it.”
As a specialized supplier of seismic isolation products, our lead rubber bearings are manufactured in strict compliance with both Chinese national standards and the AASHTO (USA) code. They offer three key advantages:
High & stable energy dissipation – With a high purity lead core and natural rubber compound, the bearing’s damping capacity does not degrade under repeated cyclic loading. This makes our building seismic isolation bearings the top choice for earthquake prone regions such as the Philippines, Japan, and Southwest China.
Large displacement capacity – Shear deformation can exceed 250%, designed specifically for near fault pulse type ground motions. Ideal for hospitals, schools, data centers – any building seismic isolation bearing application where life safety is paramount.
Excellent durability & aging resistance – The outer rubber protection system has passed accelerated aging tests equivalent to 70 years of service life, ensuring that our lead rubber bearings maintain their performance even in hot, humid, marine climates.
Our technical team also specializes in customised bridge seismic bearings – for urban viaducts, sea crossing bridges, and railway bridges. Our bridge seismic bearings (including lead rubber bearing type and friction pendulum type) effectively control girder displacement and prevent unseating or collision. In this Philippine earthquake, several nearby bridges fitted with our bridge seismic bearings also showed no damage, keeping rescue routes open.
Our lead rubber bearings and building seismic isolation bearings have been exported to multiple seismically active countries including Southeast Asia, Central Asia, and South America. They have been used in over 2 million square meters of building floor area, and our bridge seismic bearings have been installed along more than 150 km of bridges. Every earthquake becomes an “unsolicited quality inspector”, and so far we have delivered perfect scores every time.
