Heavy-Load Server Room Raised Floor System | FineCo Global
The FineCo Heavy-Load Server Room Raised Floor System is engineered for high-density data centers, enterprise server rooms, and mission-critical technical spaces. Designed to support concentrated loads from blade servers, mainframes, and heavy power distribution units (PDUs), this system utilizes dense core materials enclosed in a welded steel shell.
Key Features
High Load Resistance: Welded steel structures and dense inner cores prevent permanent deformation under concentrated loads exceeding 2,500 lbf (11.1 kN).
Controlled ESD Dissipation: Surface laminates maintain a continuous electrical resistance of 1 × 10⁶ to 1 × 10⁹ ohms to protect sensitive IT hardware.
Rigid Substructure Grid: Heavy-gauge pedestals and bolt-in stringers lock panels into a fixed matrix, eliminating lateral shifting and panel dislodgement.
Vertical Leveling Tolerance: Pedestal heads provide a ±25 mm vertical adjustment range to compensate for uneven concrete subfloors.
System Structure
A complete installation consists of four core load-transfer components:
Access Floor Panels: 600 × 600 mm modules featuring a top steel sheet resistance-welded to a formed bottom pan, filled with lightweight concrete or high-density calcium sulfate.
Pedestal Assemblies: Electro-galvanized steel threaded rods, 100 × 100 × 4 mm base plates, and die-cast heads with vibration-damping gaskets.
Bolt-In Stringers: Roll-formed steel channels that lock onto pedestal heads to form a rigid grid matrix for enhanced lateral stability.
Perimeter Trims & Gaskets: Mechanical fasteners and closed-cell foam seals that prevent air leakage and suppress acoustic resonance.

Frequently Asked Questions
Q: How do I determine the correct load rating for our server room floor?
A: Base your selection on the heaviest single equipment weight (such as a fully loaded server rack or battery cabinet) plus installation dynamics. For standard enterprise racks under 1,000 kg, a CISCA Grade Heavy Load (11.1 kN / 2,500 lbf) system with calcium sulfate or reinforced concrete core is recommended to restrict panel deflection under rolling caster wheels.
Q: What is the difference between concrete-filled and calcium sulfate panels?
A: Concrete-filled steel panels offer high structural rigidity, impact resistance, and cost-efficiency. Calcium sulfate panels provide superior acoustic dampening, a denser tactile feel, higher ultimate load capacities, and inherent non-combustible core properties for high-density facilities.
Q: How does the system handle grounding and electrostatic discharge ?
A: Panels connect electrically to pedestal heads through conductive gaskets or direct metal contact. Pedestals tie into a copper grounding grid network using mechanical clamps or copper tape, maintaining path-to-ground resistance within standard safety thresholds.
Q: What is the standard lead time for bulk project orders?
A: Production lead time ranges from 15 to 25 days, depending on order volume and custom cutouts. Partial shipments can be scheduled for large-scale data center rollouts to match on-site construction milestones.
Q: Can heavy server racks be moved on rolling casters across this floor?
A: Yes. The system withstands rolling loads specified under CISCA guidelines (tested with a 1,000-lb load over 10,000 cycles). Protective hardboard or track sheets are recommended during initial heavy rigging to prevent surface scratching on HPL finishes.
