High-Seismic Raised Access Floor System

The Fineco High-Seismic Raised Access Floor System provides structural elevated flooring engineered to maintain load integrity and lateral stability during seismic events. Built for mission-critical facilities in high-risk seismic zones, the system integrates heavy-duty welded steel panels, rigid stringer networks, and seismically rated bolted stringer pedestals with diagonal sway bracing. It isolates critical underfloor cabling, HVAC plenums, and power distribution utilities while preventing structural rack collapse or floor displacement during ground acceleration.

Rigid Bolted Stringer Grid: Bolted stringer connections lock panels into a unified horizontal diaphragm, resisting lateral shear forces and preventing panel uplift during seismic tremors.
Seismic Sway Bracing Integration: Pedestal assemblies accommodate heavy-duty lateral brace kits and seismic gussets to transfer dynamic lateral loads directly to the structural subfloor.
All-Steel Construction: Formed top and bottom steel sheets resistance-welded into a hollow core, filled with lightweight structural cement to dampen vibration and maximize acoustic performance.
Epoxy Powder Coated Finish: Electrostatically applied epoxy coating provides corrosion resistance and electrical grounding continuity across the entire grid.
Precision Height Adjustment: Heavy-duty threaded steel studs allow fine-tuning of Finished Floor Height (FFH) from 150mm to 1500mm while locking securely via vibration-proof locking nuts.

Panel: Welded steel shell filled with structural cement; available in bare finish or bonded with high-pressure laminate (HPL) or antistatic vinyl (ESD).
Stringer: Rolled steel rectangular tube with end-locking tabs, bolted directly to pedestal heads to form a rigid 600mm x 600mm grid network.
Pedestal Head: Die-cast or stamped steel head with captive studs and sound-dampening isolation gaskets to lock stringers securely in place.
Pedestal Tube & Base: Vertical galvanized steel pipe welded to a heavy-gauge base plate (100mm x 100mm x 4mm), anchored to the concrete subfloor via mechanical expansion anchors.
Seismic Bracing Kit: Heavy-gauge steel channels and angle brackets deployed diagonally between pedestals to absorb multi-directional seismic shear.

Lateral Force Resistance: Engineered to withstand horizontal acceleration up to 1.0g, complying with ASCE 7 Chapter 13 requirements for non-structural components.
Diaphragm Action: The bolted stringer and panel assembly acts as a rigid horizontal diaphragm, distributing lateral loads uniformly to perimeter seismic restraints.
Sway Mitigation: Diagonal bracing kits limit relative inter-story drift between the raised floor and the base building structure, preventing structural pounding against walls and equipment racks.
Uplift Prevention: Mechanical screw-down or corner-lock fasteners prevent panels from dislodging upward during vertical ground motion components.

Hyperscale & Colocation Data Centers: Secures heavy server racks, power distribution units (PDUs), and battery backup systems against structural shear during earthquakes, backed by successful deployments in high-seismic regions like Japan and the US West Coast.
Semiconductor Cleanrooms (ISO Class 3 - 7): Provides vibration-dampened, particle-free subfloor plenums capable of supporting heavy robotic wafer transport tracks.
Emergency Dispatch & Control Centers: Ensures uninterrupted operational continuity for 24/7 command hubs during seismic emergencies.
Telecommunication Hubs: Protects sensitive switching gear and fiber-optic distribution frames from lateral displacement.

Subfloor Preparation: Requires laser-leveled concrete subfloor with minimum compressive strength of 20 MPa, treated with dust-proofing primer.
Installation Tooling: Installed using laser levels, heavy-duty hammer drills, torque wrenches calibrated to specified clamping force, and suction cup panel lifters.
Customization Options:

• Perforated airflow panels (open area ranging from 18% to 55%) with adjustable volume control dampers.
• Custom cutout service for cable grommets, electrical floor boxes, and HVAC stub-ups executed via CNC waterjet cutting.
