Seismic Raised Access Floor System
The Fineco Seismic Raised Access Floor System is an engineered heavy-duty structural flooring solution designed to maintain grid integrity and protect critical hardware during seismic events. Comprising a rigid network of bolted steel stringers, heavy-gauge pedestals, and high-density panels, the system restrains lateral movement and vertical uplift. It isolates mission-critical infrastructure from ground motion while accommodating high-density cabling and under-floor HVAC distribution.
Key Features
Bolted Stringer Diaphragm
Mechanically fastened structural stringers lock floor panels into a unified horizontal plane, preventing lateral displacement and panel dislodgement during tremors.
Seismic Bracing Compatibility
Accommodates heavy-duty diagonal sway braces and heavy-gauge riser heads to restrict multi-directional shear forces and vertical uplift.
High-Density Core Options
Available in cementitious infill panels and all-steel welded shells capable of withstanding concentrated loads up to 1,500 lbf per panel.
Precision Leveling Assembly
Micro-adjustable pedestal heads with vibration-resistant locking nuts maintain strict finished floor height (FFH) tolerances.
Electrostatic Discharge (ESD) Control
Surface finishes provide controlled electrical resistance paths to dissipate static charges safely and protect sensitive hardware.

Seismic Performance
Code Compliance
Engineered to satisfy IBC 2021 and ASCE 7 provisions for Seismic Design Categories D through F.
Sway Resistance
Structural sway struts absorb multi-directional shear loads, reducing dynamic stress transmitted to building subfloors.
Uplift Restraint
Mechanical locking fasteners prevent panels from disengaging from the stringer grid during vertical seismic accelerations.
Verification Testing
Assembly configurations undergo simulated seismic shaking table testing to verify structural stability under site-specific peak ground acceleration (PGA) thresholds.
Typical Applications
Hyperscale & Colocation Data Centers
Secures heavy enterprise server cabinets, UPS battery arrays, and power distribution units against lateral shock.
Semiconductor Cleanrooms
Maintains subfloor gas and fluid utility routing under strict vibration and seismic constraints.
Command & Control Centers
Protects 24/7 operational dispatch consoles and communication racks from sudden ground displacement.
Financial Trading Floors
Supports high-density workstation cabling grids and structural stability in high-rise commercial facilities.
Installation & Customization
Subfloor Preparation
Requires cured concrete subfloors treated with anti-dust sealers; laser leveling establishes grid reference lines prior to pedestal positioning.
Anchoring Protocol
Pedestal base plates (100 x 100 mm minimum) are anchored using heavy-duty expansion bolts or structural epoxy anchors.
Custom Cutouts
Water-jet cutting accommodates cable grommets, air grilles, and brush modules while preserving perimeter structural edge strength.
Height Adjustability
Telescopic pedestal tubes accommodate under-floor plenum clearances from 300 mm up to 1,500 mm.
Standards & Quality
CISCA
Complies with Ceilings & Interior Systems Construction Association test protocols for access floors.
EN 12825
Classified according to European standards for raised access floors regarding ultimate load and safety factors.
ASTM E84 / UL 723
Surface burning characteristics meet Class A flame spread and smoke development ratings.
Material Traceability
Raw steel thickness, galvanization micron depth, and concrete core density are inspected per production batch prior to assembly.
Manufacturing & Project Support
Production Facility
45,000-square-meter automated manufacturing plant equipped with CNC laser cutting lines, multi-station stamping presses, and robotic electrostatic powder coating booths.
Capacity
Annual output exceeds 1.2 million square meters of raised flooring components, maintaining stable lead times for enterprise-scale deployments.
Engineering Support
In-house structural engineering team provides shop drawings, load distribution calculations, and custom seismic bracing layouts tailored to structural engineer of record (SER) specifications.
Packaging & Logistics
Components are palletized, moisture-wrapped, and containerized with clear pallet manifests to streamline site staging and distribution.
Frequently Asked Questions
Q: How does this seismic raised floor system differ from standard commercial access floors?
A: Standard commercial floors rely on gravity-fit or snap-on systems designed for general office environments. The Fineco seismic system integrates a heavy-duty bolted stringer network, mechanical locking fasteners, and diagonal sway struts designed to absorb lateral shear forces, prevent panel uplift, and protect heavy hardware from tipping during seismic events.
Q: What seismic zones and building codes are supported?
A: The system complies with IBC Chapter 16, ASCE 7 seismic provisions, and GR-63-CORE Zone 4 requirements. Project-specific calculations can be supplied to match local seismic design categories (SDC D, E, and F) and specific spectral acceleration parameters.
Q: What is the maximum concentrated load capacity for server rack installations?
A: Panels support concentrated loads ranging from 4.45 kN (1,000 lbf) to 6.67 kN (1,500 lbf) on a 1-inch square indenter with a permanent deflection of less than 0.25 mm, satisfying CISCA Grade A requirements for high-density server rooms.
Q: Can the finished floor height (FFH) be adjusted after installation?
A: Yes. The threaded stud assembly on the pedestal head allows micro-adjustments of plus or minus 25 mm for leveling after the main frame is erected, while major height parameters are selected via the appropriate pedestal extension tube during the procurement phase.
Q: What documentation is provided for structural engineering review?
A: We supply complete technical data sheets, CISCA and EN 12825 test reports, CAD and BIM model blocks, material mill certificates, and project-specific seismic calculation packages stamped by professional engineers upon request.
Q: What are the standard lead times for bulk project orders?
A: Standard production lead times range from 20 to 30 days depending on order volume, custom cutouts, and finish specifications. We coordinate container loading schedules directly with freight forwarders to align with site delivery milestones.
