The raised height of anti‑static access floor refers simply to the vertical distance between the finished floor surface and the original ground. This under‑floor cavity is primarily reserved for cable routing, pipeline arrangement and acts as an air supply plenum for air conditioning systems. Three major factors determine the required raised height:

1. Quantity and category of cables. If only a small quantity of network cables and power cords need to be laid, a clearance of 10 to 20 centimeters will suffice. For computer rooms packed with dense equipment and numerous cables, or projects requiring separation of strong and weak current circuits, a larger under‑floor space of 30 to 50 centimeters or above is necessary for neat wiring.

2. Air conditioning supply requirements. Many data centers adopt under‑floor air supply systems, where cold air flows through ventilation holes on floor panels to cool IT hardware. Under such circumstances, the raised cavity serves as a static pressure box, which demands sufficient vertical space to ensure uniform airflow distribution. More stringent air cooling standards generally call for a greater raised height.

3. On‑site structural limitations. Some renovation projects have limited floor‑to‑ceiling clearances; excessively high under‑floor cavities will reduce usable indoor headroom. A balance must be struck between cabling demands and vertical space constraints. Standard raised heights for conventional server rooms range from 10 to 60 centimeters, while customized higher clearances are available for special projects.

Recommendation: Communicate fully with construction contractors at the design stage, clarifying your total cable volume, under‑floor air supply demands and floor height restrictions. Let professionals calculate a rational raised height for your project instead of making arbitrary decisions. Excessive clearance wastes space, while insufficient height will create obstacles for additional cable laying in later phases.
