Product Description
Structural Seismic Isolation & Civil Engineering
Structural Damping Disc Spring Stack for Buildings and Heavy Foundations
In civil engineering and heavy infrastructure design, protecting structures from seismic activity, heavy machinery vibration, and structural settling is critical. Jiangsu Sanzhong Elastic Technology Co., Ltd. designs and manufactures heavy-duty structural Disc Spring Stack systems that serve as elastic dampening elements for building foundations, bridge supports, and heavy industrial machinery basements. These large-scale spring assemblies absorb high-energy shocks and decouple sensitive structures from ground vibrations.

[Controlled Energy Dissipation & Return]
Our structural spring stacks are engineered to support massive static loads while remaining flexible enough to absorb dynamic kinetic energy. By utilizing specialized series-parallel combinations, we can design a stack that provides soft, dampening characteristics for minor daily vibrations, but stiffens progressively during major seismic events. This progressive performance protects critical structural connections from catastrophic failure.
Target Client Applications
- Machinery Isolation Foundations: Positioned under heavy forging hammers, stamping presses, and large diesel generators to damp ground vibrations.
- Bridge Expansion Bearings: Installed in highway and railway bridge piers to accommodate structural expansion and concrete shrinkage.
- Seismic Building Isolators: Integrated into base isolation systems for buildings in active seismic zones to reduce lateral forces.
