Product Overview
Raised Floor Ventilation Systems
This steel ventilated floor panel offers exceptional airflow, with a ventilation rate of 25%. When paired with the matching steel adjuster, the ventilation rate can be customized from 0 to 25%. Designed as a steel bare panel, it features an anti-static epoxy coating on the surface, with no decorative finishes applied. This sample finish is white, though we also offer custom colors like light grey, dark grey, or black to match your preferences.
The panel’s upper surface is designed with evenly spaced round holes, ensuring a uniform airflow distribution during ventilation. This design not only maximizes efficiency but also provides outstanding load-bearing capabilities. The thickness of the perforated panel can be customized between 1.0mm to 4.0mm, while the back is reinforced with 12pcs thickened steel pipes welded in place to increase panel strength. The pipe thickness can also be customized, ranging from 1.0mm to 3.0mm.
Furthermore, this ventilated floor panel is fully compatible with steel cement panels, using the same accessory system for easy installation. It’s the perfect solution for tailored ventilation and heavy-duty flooring needs.

How do steel raised ventilated floors interact with equipment in the computer room?
Heat dissipation and air circulation
Through vents, the raised floor guides cold air to the bottom of the equipment, helping the equipment to dissipate heat and ensure stable temperature.
Hot and cold aisle management
Raised floors can create cold and hot aisles, optimize air flow by adjusting ventilation rates, and improve heat dissipation efficiency.
Working with air conditioning
Working with the air conditioning system, the raised floor evenly distributes cold air, reduces air conditioning load, and improves energy efficiency.
Cable management
Raised floors provide space for cable management to avoid interfering with equipment operation while improving air flow.
Customization and height adjustment
The floor height and ventilation design can be adjusted according to equipment requirements to optimize air circulation and heat dissipation.
In this way, steel raised ventilated floors help improve the ventilation effect of the computer room, optimize equipment heat dissipation and the overall environment

What is the difference between the use scenarios of raised floors with low ventilation rates and those with high ventilation rates?
- Low ventilation rates are typically used for equipment with low heat loads or devices insensitive to temperature fluctuations. They provide mild ventilation, making them suitable for data center raised floors, server room flooring, or computer room flooring requiring precise temperature control without relying on large volumes of cooled air.
- High ventilation rates are designed for raised access floors in environments with high heat loads, such as data center flooring or modular raised floors. They deliver greater airflow to enhance heat dissipation and maintain optimal operating temperatures, ensuring efficient cooling for data center infrastructure.

Product application scenarios
Yes, the top design will remain the same, but the loading performance can be improved by increasing the thickness of the steel plate or adding support beams at the bottom.
Yes, they can. Sometimes, we may install the steel frame on the side of the floor edge to match the different kinds of floors. Please refer to pictures from the above products list of “AF250 Steel Perforated Floor”.
Yes, we can use a steel damper. The ventilation rate of the steel damper is adjustable, so we can achieve variable ventilation needs by adjusting the damper.
