Hardware & Steelwork
DIS processes over 2,000 tons of steel each year. Mounting plates, sole plates, anchor bolts and fasteners are designed and supplied alongside the bearings.
Dynamic Isolation Systems processes over 2,000 tons of steel a year. Steel mounting plates, sole plates, anchor bolts and fasteners are routinely fabricated and supplied alongside DIS isolators.
For the I-40 Bridge over the Mississippi River in Memphis, Tennessee, DIS supplied 112 isolators plus tapered sole plates, masonry plates, and all mounting hardware.
DIS also designs specialty bearings for non-seismic applications such as ship loaders, where the bearings control forces during oil off-loading from tankers. For Caltrans's Richmond–San Rafael Bridge, six feet above the waterline, DIS developed corrosion-resistant assemblies with low-permeability rubber and stainless steel.
Custom configurations
Tapered sole plates, masonry plates, and full anchor packages are designed and supplied per project. Marine and chemically aggressive environments use stainless steel and low-permeability rubber.
Specialty bearings
Non-seismic specialty bearings for ship loaders, gantries, and submerged structures are available. We've delivered bearings permanently submerged in fresh water at ~200 ft depth.
Other products
Base Isolators
Laminated rubber and steel bearings with steel flange plates. Ninety percent of our isolators feature an energy-dissipating lead core for high damping.
Sliding Isolators
A PTFE (Teflon) disc sliding on stainless steel. Used alongside LRBs to tune the response of an isolation system and handle rotations.
Viscous Wall Dampers
A steel tank, an inner vane and a high-viscosity fluid reduce inter-story drift by more than 50%. Compact, maintenance-free, and architecturally flexible.
Got a project where downtime isn't an option?
Our engineers work alongside you from concept through installation. When we're brought in during the design phase, total project cost often drops by up to 30%.
