Extra-Heavy-Duty Raised Access Floor System | Fineco Global
The Fineco Extra-Heavy-Duty Raised Access Floor System is engineered for high-density data centers, heavy electrical control rooms, and industrial infrastructure requiring exceptional structural capacity. Built around a solid steel shell injected with a high-density, lightweight cementitious core or high-strength calcium sulfate core, this system provides rigid underfloor plenum management for high-capacity cabling and underfloor air distribution (UFAD) while withstanding extreme concentrated and rolling loads without permanent deformation.
Key Features
High Load-Bearing Capacity: Engineered for concentrated point loads exceeding 6.8 kN (1,500 lbf) to 11.1 kN (2,500 lbf) meeting CISCA Extra-Heavy-Duty standards.
Rigid Monolithic Construction: Spot-welded top and bottom steel sheets encapsulate a controlled-density cement core, eliminating hollow resonance and maximizing torsional rigidity.
Continuous Path Grounding: Direct metal-to-metal contact between stringers, pedestals, and panels ensures reliable electrostatic discharge (ESD) mitigation.
Corrosion-Resistant Finish: Epoxied and phosphate-treated steel components withstand humid underfloor plenum environments.
System Structure
Surface Finish: High-Pressure Laminate (HPL) / Conductive Vinyl / Bare Steel
Top Steel Sheet: Deep-drawn SPCC cold-rolled steel (Thickness: 1.2 mm - 2.0 mm)
Core Material: Lightweight Cementitious Core / High-Density Calcium Sulfate
Bottom Steel Sheet: Embossed/Dimpled SPCC cold-rolled steel
Support Grid: Heavy-duty bolt-down steel pedestals & snap-on tubular stringers

Seismic Performance
Mission-critical facilities demand uninterrupted structural integrity during seismic events. The Fineco Extra-Heavy-Duty system incorporates:
Rigid Bolt-Down Pedestals: Base plates anchored directly to the subfloor via mechanical expansion bolts.
Heavy-Duty Lateral Bracing: Diagonal seismic struts installed at 3-meter intervals for FFH exceeding 800 mm.
Compliance Testing: Tested in accordance with Telcordia GR-63-CORE (Zone 4) and ASCE 7 requirements, preventing lateral shear failure and panel dislodgement during seismic shock. (Complete structural engineering calculation reports available for client submittal files).
Typical Applications
Hyperscale & Colocation Data Centers: Server halls housing heavy blade server cabinets and battery energy storage systems (BESS).
Electrical Substations & Control Rooms: SCADA control platforms supporting heavy industrial switchgear cabinets.
Cleanroom Facilities: Semiconductor fabrication cleanrooms requiring particle-free, vibration-damped subflooring.
Broadcast & Telecommunications Hubs: Master control facilities requiring high-density cable routing and equipment weight distribution.

FAQ
Q: What is the difference between calcium sulfate and cement-filled steel panels for extra-heavy-duty applications?
A: Cement-filled steel panels offer superior impact resistance and acoustic dampening, making them ideal for high-vibration data halls. Calcium sulfate panels provide higher inherent fire resistance (A1 non-combustible) and denser screw-retention properties. Fineco engineers evaluate your specific MEP load requirements to recommend the optimal core material.
Q: How does the system prevent deflection under heavy rolling loads ?
A: Our extra-heavy-duty panels utilize a 2.0 mm top steel plate combined with continuous high-tensile steel stringers bolted to heavy-gauge pedestals. This distributes dynamic point loads across a multi-pedestal grid, restricting panel deflection under rolling caster wheels to under 1.5 mm (verified via CISCA rolling load testing protocols).
Q: Can this raised floor system integrate with existing underfloor HVAC (UFAD) layouts?
A: Yes. The system accommodates high-capacity perforated steel panels and damper-controlled airflow modules. We match stringer grid heights to existing plenum configurations, ensuring zero pressure drops or air leakage across layout interfaces.
Q: What documentation is provided for engineering and seismic submittals?
A: We provide complete submittal packages including third-party test reports (CISCA/EN 12825), factory mill test certificates for steel raw materials, seismic calculation compliance notes (Telcordia GR-63-CORE), and customized CAD/Revit shop drawings.
Q: What is the standard production lead time for large-scale data center orders?
A: Standard production lead time for volume orders (up to 5,000 square meters) is 15 to 20 working days. Custom cutouts, specialized HPL finishes, or anti-static vinyl laminations may add 3 to 5 working days.
