🏗️ What Makes Racks “Seismic”?
Seismic racks are built to handle lateral and vertical forces that occur during an earthquake. They include:
-
Reinforced frames and beams for greater structural integrity.
-
Heavy-duty base plates that anchor securely to the floor.
-
Cross bracing or moment-resisting frames to limit sway or collapse.
-
High-strength fasteners and connectors that hold the system together under movement.
All components are designed to comply with seismic design standards set by codes like the IBC (International Building Code) and RMI (Rack Manufacturers Institute).
🌎 Why Seismic Racks Are Important
-
Safety: Prevents rack collapse that could endanger workers or damage goods.
-
Asset protection: Reduces the risk of losing valuable inventory during seismic events.
-
Compliance: Many municipalities require seismic-rated systems for permitting.
-
Business continuity: Ensures faster recovery and minimal downtime after an earthquake.
⚙️ Applications
Seismic racking is used in:
-
Warehouses and distribution centers in seismic zones (California, Washington, Oregon, Alaska, etc.)
-
Cold storage and high-density warehouses, where tall racks and heavy loads amplify seismic risks.
-
Manufacturing plants where equipment or materials need secure, compliant storage.
🧩 Types of Seismic Racking
You can find seismic versions of common rack types, including:
-
Selective pallet racks – standard warehouse racking with reinforced seismic features.
-
Drive-in and drive-through racks – designed with added lateral support.
-
Cantilever racks – strengthened to resist side-to-side motion.
-
Push-back and pallet flow racks – with engineered supports and anchor points for seismic safety.
