Do cable tray manufacturers use seismic bracing
Seismic bracing, typically made of high-strength metal, is key component specifically designed to enhance the stability and safety of cable tray systems during earthquakes. In regions prone to seismic activity, ensuring that your cable tray system is capable of withstanding such events is vital. For over 60 years, the mechanical, electrical, and fire protection trades have relied on TOLCO seismic bracing solutions.
