Lateral & longitudinal seismic bracing assemblies that restrain non-structural MEP services — pipe, multi-pipe trapeze, cable tray and rectangular HVAC duct — and transfer seismic load to the building structure.
A seismic bracing system is the engineered assembly of channel, braces, connectors and anchors that holds building services in place during an earthquake. Instead of letting pipes, ducts and cable trays swing, drop or rupture, the bracing transfers seismic forces back into the structure — protecting the services, the building and the people inside.
Our systems cover the full range of configurations seen on real MEP projects: single-pipe lateral and longitudinal braces, multi-pipe and trapeze racks, rectangular HVAC duct bracing, and cable tray bracing — all built from finished, compatible components for fast, repeatable installation.
