Aluminum Grating Panel

Aluminum Grating Panel | Maximum Airflow for High-Density Data Center Cooling

High-density server rooms generate intense heat that standard perforated panels cannot remove fast enough. The Aluminum Grating Panel from Huahong Floor solves this problem. Manufactured from high-strength aluminum alloy with an open grid structure, this panel delivers ventilation rates of 40%-70% – far exceeding standard perforated tiles. Permanent anti-static, corrosion-resistant, and lightweight, it is the professional choice for high-heat environments.

What Is an Aluminum Grating Panel?

An Aluminum Grating Panel is a raised access floor panel with an open grid (grating) structure instead of solid surface or small perforations. The grid consists of parallel bars with open spaces between them, allowing maximum airflow from the underfloor plenum directly to equipment intakes. This design is ideal for high-heat density environments where standard perforated panels cannot provide sufficient cooling.

【Aluminum Grating Panel】 FAQ

Q1: Does the Aluminum Grating Panel meet national and industry standards?

Answer: Yes. The Aluminum Grating Panel from Huahong Floor strictly complies with GB/T 36340-2018 (raised access floors) and SJ/T 10796-2001 (anti-static floors). The aluminum alloy material meets applicable ASTM and EN standards. Grating integrity, load capacity, flatness, and anti-static properties are tested per batch. Fire rating is Class A non-combustible. Corrosion resistance is inherent to the aluminum material – no coating required. For international projects, Huahong can provide compliance documentation for ISO, ASTM, or EN standards upon request. The one-piece integrated grating structure also meets applicable seismic and safety codes for raised access floors.

Q2: Is the Aluminum Grating Panel suitable for data center ventilation? What ventilation rate can I achieve?

Answer: Absolutely. The Aluminum Grating Panel is specifically designed for high-heat data center environments where standard perforated panels provide insufficient airflow. Ventilation rates range from 40% to 70% open area – far exceeding the 30-60% range of perforated panels. For context: 70% open area means nearly three-quarters of the panel surface is open for airflow, delivering cooling air with very low resistance. This is ideal for high-density racks (8-12+ kW per rack), cloud computing clusters, HPC environments, and any facility where heat load is the primary constraint on server density. The open grating structure also allows for uniform airflow across the entire cold aisle, reducing hot spots and improving CRAC efficiency.

Q3: Is the panel strong enough for heavy server racks? Does the open structure compromise load capacity?

Answer: Yes – the Aluminum Grating Panel is engineered for both high ventilation and high load capacity. Available models: FS800 (454 KG) – Standard server rooms. FS1250 (567 KG) – Medium density data centers. FS1500 (680 KG) – High-density racks. FS2000 (907 KG) – Heavy equipment. The one-piece integrated grating process ensures that all bars are formed as a single structural unit – no separate bars that can shift or loosen under load. The load is distributed across the entire grid structure, not just individual bars. For most standard server racks with foot loads of 200-300 KG, FS800 or FS1250 models are sufficient. Despite the open structure (up to 70% open area), the remaining aluminum material is strategically placed to maintain continuous load paths. Heavy-duty models with thicker bars are available for UPS rooms or mainframe installations.

Q4: Will the Aluminum Grating Panel rust or corrode over time, especially in humid environments?

Answer: No. The Aluminum Grating Panel never rusts. Aluminum naturally forms a thin, transparent oxide layer when exposed to air. This layer is hard, non-porous, and self-healing – if scratched, the oxide immediately reforms. No painting, plating, or sealing is required. For coastal data centers, high-humidity environments, or any facility where steel panels would rust, aluminum grating panels maintain their integrity indefinitely. Steel grating panels (where available) rely on galvanization or paint coatings that eventually fail – especially at cut edges and weld points. Aluminum has no such weakness. This corrosion resistance is a primary reason engineers specify aluminum for cooling towers, marine environments, and any application with moisture exposure. For data centers with humidification systems or coastal locations, aluminum is the superior choice.

Q5: Can the grating spacing or ventilation rate be customized for my project?

Answer: Yes. Huahong Floor supports customizable grating density and ventilation rates for the Aluminum Grating Panel. Options include: Ventilation rate – 40%, 50%, 60%, or 70% open area. Bar spacing – Narrower gaps for higher support density, wider gaps for maximum airflow. Bar thickness – Standard or heavy-duty for increased load capacity. Surface texture – Smooth for easy rolling, serrated for slip resistance. Provide your required CFM per panel, rack heat load (kW), or target open area percentage, and Huahong will recommend or manufacture the appropriate grating pattern. This customization ensures you achieve the exact cooling performance needed without over-ventilating (wasting cold air) or under-ventilating (creating hot spots). Contact Huahong with your cooling requirements for a recommendation.

Q6: How does the Aluminum Grating Panel compare to steel grating or heavy perforated panels?

Answer: Four key advantages make aluminum grating superior for data center applications. First, corrosion resistance – Aluminum never rusts; steel grating rusts over time, especially in humid environments. Second, weight – Aluminum is 1/3 the weight of steel, making installation and cable access much easier. Third, anti-static – Aluminum is naturally conductive permanently; steel grating requires grounding continuity through coatings that can fail. Fourth, maintenance – Aluminum requires none; steel grating needs periodic rust inspection and touch-up. Compared to heavy perforated panels (60% max open area), aluminum grating provides higher ventilation (70% vs 60%) , lower airflow resistance, and better visibility through the panel. The only potential disadvantage is cost – aluminum has higher initial material cost. However, the longer service life (30+ years vs 10-15 years) and zero maintenance make aluminum more economical over the full building lifecycle.

Q7: Does Huahong Floor provide customization and after-sales support for Aluminum Grating Panels?

Answer: Yes. Huahong Floor provides comprehensive support for the Aluminum Grating Panel. Customization options include: ventilation rate (40%-70% open area), bar spacing and thickness, panel dimensions (600×600mm standard or custom), load rating (FS800 to FS2000+), and surface finish (natural aluminum or optional treatment). Installation services include: on-site measurement, system design, professional installation by trained crews, and post-installation airflow verification. Warranty : 5-year structural warranty covering material defects, load performance, and grating integrity. After-sales support: technical documentation, remote troubleshooting, replacement panels for verified defects, and optional on-site inspection for large projects. Contact Huahong with your specific requirements for a customized proposal.

Installation Overview

Standard Installation Steps
