Industrial Heavy-Load Raised Floor System
The Industrial Heavy-Load Raised Floor System is a modular infrastructure solution engineered for concentrated static loads and dynamic rolling equipment up to 2,500 kg per panel. Designed for mission-critical industrial facilities, hyperscale data centers, and semiconductor cleanrooms, the system establishes a uniform under-floor plenum for high-density cable routing and HVAC distribution while maintaining strict structural rigidity and grounding continuity.
Key Features
Welded Steel Construction: Cold-rolled SPCC steel shell resistance-welded and filled with high-density lightweight concrete, eliminating hollow acoustics and maximizing impact resistance.
Interlocking Grid Matrix: Bolt-stringer framework secures each pedestal head, restricting lateral displacement and distributing heavy mechanical loads evenly across the subfloor.
Controlled ESD Dissipation: Surface laminates provide a stable electrical resistance of 1 × 10⁶ to 1 × 10⁹ ohms, preventing electrostatic discharge in sensitive technical spaces.
Corrosion Resistance: Multi-stage zinc phosphating and epoxy powder coating (minimum 60-micron thickness) rated for humid and corrosive industrial environments.
System Structure
An installation relies on three precision-engineered components working in direct load-bearing alignment:

Material & Specification |
Function |
|
Heavy-Duty Panel |
SPCC steel top/bottom shell, lightweight concrete core; thickness: 35–45 mm |
Bears direct vertical and rolling loads; provides top wear surface |
|
Bolted Stringer |
Cold-formed rectangular steel tube (0.8–1.5 mm wall thickness) |
Connects pedestal heads to form a rigid grid matrix |
|
Steel Pedestal |
Threaded steel rod, heavy-gauge base plate (100 × 100 × 4 mm), die-cast head |
Adjusts finished floor height (150–1500 mm); transfers loads to subfloor |

Seismic Performance
Sway Bracing Compatibility: Engineered to accept heavy-duty seismic sway braces and rigid-frame pedestal anchors to prevent structural shear during tremors.
Positive-Lock Uplift Screws: Stringer fasteners prevent vertical panel displacement during high-frequency seismic events.
Dynamic Drift Tolerance: System absorbs subfloor deflection without compromising load capacity or grounding continuity.
Typical Applications
Data Centers & Colocation Facilities: Main server halls housing heavy mainframes, UPS battery racks, and high-volume CRAC units.
Semiconductor Fabs: Cleanrooms requiring anti-static flooring, high rolling load resistance for wafer transport carts, and strict particle control.
Industrial Control & Power Substations: SCADA control rooms, turbine monitoring floors, and electrical switchgear bays.
Automotive Assembly: Robotics and PLC control enclosures exposed to heavy maintenance traffic.
Installation & Customization
Leveling Tolerance: Threaded pedestal collars allow fine-tuning of finished floor height within ±1.5 mm across a 10-meter span.
Custom Cutouts: Factory-machined cable grommets, brush strips, and perimeter ventilation grates (up to 55% free airflow area) built to MEP layout drawings.
Surface Options: High-Pressure Laminate (HPL), Conductive PVC, and Bare finish ready for secondary site-applied flooring tiles.

FAQ
Q: What is the maximum rolling load capacity for this system?
A: Extra heavy-duty grades withstand rolling loads up to 6.0 kN tested across 20,000 cycles per EN 12825 standards, preventing panel edge deformation under pallet jacks or server transport carts.
Q: How is electrical grounding maintained across the floor grid?
A: Grounding continuity is established via conductive stringer gaskets and direct metal-to-metal contact between panels, stringers, and steel pedestals, terminating at designated subfloor earth points.
Q: Can this flooring system accommodate underfloor HVAC supply plenums?
A: Yes. The structural grid withstands underfloor static air pressure up to 300 Pa without leakage when perimeter joints are sealed with closed-cell neoprene gaskets.
Q: What is the standard lead time for container-load orders?
A: Standard production lead time is 20 to 25 days following shop drawing approval and deposit receipt, shipped via standard 40-foot high-cube export containers.
Q: Do you provide installation supervision for overseas projects?
A: We provide comprehensive installation manuals, shop drawing packages, and remote engineering support. On-site technical supervision is available upon contractual agreement.
