Perforated Panel

Perforated Panel | Precision Airflow for Data Center Cooling

High-density servers generate intense heat. Without proper airflow, hot spots develop, equipment throttles, and reliability suffers. The Perforated Panel from Huahong Floor delivers the solution. Manufactured from thickened cold-rolled steel with uniformly distributed perforations, this panel provides efficient ventilation, stable load capacity, and anti-static protection. Designed specifically for cold aisle/hot aisle containment systems, it is the preferred choice for precision computer room ventilation flooring.

What Is a Perforated Panel?

A Perforated Panel is a modular raised floor panel with evenly spaced holes across its surface. It replaces solid panels in front of server racks to deliver cooling air from the underfloor plenum directly to equipment intakes. The all-steel construction provides both ventilation and load-bearing capability.

【Perforated Panel】 FAQ

Q1: What ventilation rate do I need for my server room?

Answer: The required ventilation rate depends on your rack heat density and underfloor air supply pressure. General guidelines: 30-40% ventilation – Low to medium heat loads (3-5kW per rack), standard server rooms with moderate cooling needs. 45-50% ventilation – Medium to high heat loads (5-8kW per rack), typical data center cold aisles. 55-60% ventilation – High heat loads (8-12kW+ per rack), high-density computing, hot aisle containment systems. Huahong Floor supports customizable ventilation rates from 30% to 60% . For new projects, perform a CFD analysis or consult with Huahong to calculate the optimal open area based on your specific CRAC flow rate, plenum depth, and rack layout. Incorrect ventilation rates cause either under-cooling (hot spots) or over-cooling (wasted energy).

Q2: Is the Perforated Panel strong enough for heavy server racks?

Answer: Yes. The Perforated Panel uses thickened cold-rolled steel with one-piece stamping forming – no weak weld points. Elastic deformation is ≤2.0mm under load. Load capacity depends on the model you select: FS662 (363 KG) – Light ventilation areas. FS800 (454 KG) – Standard server rooms. FS1250 (567 KG) – Medium density racks. FS1500 (680 KG) – High-density cabinets. FS2000 (907 KG) – Heavy equipment zones. For most standard server racks with foot loads of 200-300KG, FS800 or FS1250 models are sufficient. For heavy UPS equipment or high-density storage arrays, select FS1500 or FS2000. Unlike some competitors that reduce steel thickness to lower cost, Huahong uses full-thickness steel to ensure structural integrity even with perforations.

Q3: Do the holes get blocked with dust or debris? How do I clean the panel?

Answer: The Perforated Panel is designed for easy cleaning. The surface is smooth with electrostatically sprayed finish, which resists dust accumulation. For regular maintenance: Daily – Dry mop or vacuum the surface to remove loose dust. Weekly – Use a damp cloth or mop with mild soap and water for deeper cleaning. For blocked holes – Use a vacuum with brush attachment or compressed air from the underside to clear any debris. Do not use high-pressure water jets or abrasive cleaners – these can damage the anti-static coating. The smooth surface and burr-free hole edges prevent debris from sticking. Compared to cast or rough-surfaced perforated tiles, Huahong perforated panels are significantly easier to keep clean. For clean room environments, specify high-ventilation models with more holes to maintain airflow even with minor surface dust.

Q4: Can I customize the perforation pattern or ventilation rate?

Answer: Yes. Huahong Floor supports customizable ventilation rates from 30% to 60% . You can specify the exact open area percentage needed for your cooling design. Standard patterns include: uniform hole distribution across the entire panel, high-density perforation zones for targeted cooling, and edge-to-edge perforation for maximum airflow. For large projects, custom hole diameters and spacing patterns are available. Provide your required CFM per panel or target open area percentage, and Huahong will manufacture accordingly. This customization ensures you neither under-ventilate (causing hot spots) nor over-ventilate (wasting cold air and energy). Contact Huahong with your cooling requirements for a recommendation.

Q5: What is the difference between Huahong Perforated Panel and ordinary perforated tiles?

Answer: Five key differences distinguish Huahong Perforated Panel from ordinary products. First, steel thickness – Huahong uses thickened cold-rolled steel; many competitors reduce thickness to cut cost, sacrificing load capacity. Second, forming method – One-piece stamping and forming, no separate welding points; ordinary panels may use welded assemblies that can fail. Third, perforation quality – Precision punching with no burrs, uniform hole distribution; ordinary panels often have inconsistent holes or sharp edges. Fourth, load capacity – Huahong panels maintain higher strength despite perforations; ordinary panels deform more easily. Fifth, dual brand quality control – Huahong and Ouli brands follow strict production standards; ordinary products have inconsistent quality. For data centers where reliability and cooling efficiency matter, Huahong panels deliver longer life and better performance.

Q6: Does Huahong provide installation and after-sales support for Perforated Panels?

Answer: Yes. Huahong Floor provides comprehensive support. Installation services include: on-site measurement and layout design, professional installation by trained crews (available in many regions), system integration with existing pedestal grids, and post-installation flatness and airflow verification. For customers using their own contractors , Huahong provides detailed installation guides and remote technical support. Warranty : 5-year structural warranty covering steel integrity, perforation quality, load performance, and anti-static properties. After-sales support : Technical documentation, replacement panels for verified defects, and optional on-site inspection for large projects. Customization support : Ventilation rate customization, edge finish options (conductive strip or borderless), and load model selection. Contact Huahong with project details for a complete support proposal.

Q7: Can Perforated Panels be used with underfloor air supply systems?

Answer: Absolutely. Perforated Panels are specifically designed for underfloor air distribution (UFAD) systems common in data centers. The panel sits on adjustable pedestals above the concrete slab, creating a pressurized air plenum. The CRAC/CRAH unit pushes cold air into the plenum. Air naturally rises through the perforations in panels placed in the cold aisle. The uniform hole distribution ensures consistent airflow across the entire panel face. For best results: Ensure minimum plenum depth of 300mm (12 inches) for proper air distribution. Seal cable cutouts in solid panels to prevent air leaks. Use gasketed pedestals or edge seals to prevent air bypass. Coordinate ventilation rate with your cooling design – higher perforation panels deliver more airflow but also reduce plenum static pressure. Huahong can help calculate optimal ventilation for your specific CRAC flow rate and room layout.

Installation Guidelines
