1. Floor Panels

Floor panels are the primary surface of the raised flooring system, typically measuring 24” x 24” or 600mm x 600mm. Constructed from materials like steel-encased cement, aluminum, or calcium sulphate, panels are available with finishes such as high-pressure laminate (HPL), vinyl, or conductive coatings to meet aesthetic and performance needs.

2. Pedestals

Pedestals are adjustable, corrosion-resistant supports that elevate the floor panels. Made from galvanized steel or aluminum, they allow for precise leveling on uneven subfloors and can be adjusted to heights ranging from 6 to 48 inches, depending on plenum requirements.

3. Stringers

Stringers are horizontal cross-members that connect pedestals, enhancing lateral stability and load distribution. They are essential for high-traffic areas or facilities with heavy equipment, ensuring the system remains rigid and secure.

4. Perforated and Airflow Tiles

Perforated tiles feature openings that allow cool air to flow from the plenum to equipment racks. Airflow tiles are designed with varying perforation patterns (e.g., 25% to 56% open area) to optimize cooling efficiency based on rack density and heat load.

5. Understructure Framework

The understructure comprises the entire support system, including pedestals, stringers, and bracing. It is engineered to withstand dynamic loads, seismic activity, and environmental stresses, ensuring long-term reliability.

6. Accessories

Accessories like cable cutouts, grommets, grounding systems, ramps, and railings enhance functionality and safety. For example, brush grommets prevent air leakage around cable openings, improving cooling efficiency.

⚙️Types of Raised Flooring Systems for Data Centers

Different data centers have unique requirements, and raised flooring systems are available in various configurations to meet these needs. Here are the primary types:
