Product Description

Building anti-seismic products are flexible isolation devices made by alternately stacking multiple layers of rubber and steel plates through vulcanization. This kind of product has capacities of strong vertical bearing and horizontal displacement, and reset function, as well as support and isolation functions.

Anti-seismic devices isolate and dissipate seismic energy through flexible isolation layers to reduce the transmission of seismic energy to the superstructure. It can not only ensure the overall safety of the structure, but also prevent the damage of non structural components, avoid secondary disasters caused by structural damage, and ensure the safety of human life and property.
