In the construction and renovation project of data centers in Shanghai, floor selection directly affects load-bearing capacity, cable management, heat dissipation, and anti-static performance. This article, from the perspective of a procurement guide, systematically compares German Meilu flooring with common raised floor materials in terms of performance, installation, and acceptance specifications, helping Shanghai data center engineers and procurement decision-makers develop compliant and efficient installation solutions.
Overview of German Merlu flooring
German Merlu flooring is represented by its modular raised-floor systems, which emphasize the uniformity of the materials used and the precision of the manufacturing process. During the selection process, check the product's material composition, surface treatment, fire rating, and anti-static indicators. At the same time, request the manufacturer to provide third-party inspection reports and product certificates of conformity, ensuring that local construction in Shanghai can meet the requirements for project acceptance and maintenance.
Comparison of Commonly Used Laying Materials in Data Centers in Shanghai
Common raised floor materials used in Shanghai computer rooms include steel honeycomb core panels, steel core panels, calcium sulfate (gypsum) panels, and on-site cast concrete surface layers. Different materials have their own focuses in load-bearing capacity, vibration isolation, moisture resistance, and fire resistance. A comprehensive evaluation should be conducted in combination with the equipment density of the computer room, air conditioning system, and cable laying methods to ensure long-term stable operation.
Characteristics of steel and honeycomb core panels
Steel honeycomb core panels are lightweight yet have high load-bearing capacity, offering excellent flatness and modular installation advantages, often used in conjunction with galvanized or corrosion-resistant treated face sheets. Its disadvantages include the need for enhanced protection in high-humidity or corrosive environments, and fire resistance and anti-static performance must be improved through coating and grounding design to meet the requirements of the computer room.
Calcium sulfate and characteristics of concrete flooring
Calcium sulfate (gypsum) composite flooring has high density, good compressive strength and sound insulation properties, and is commonly used in computer rooms where high load-bearing capacity and fire resistance ratings are required ； Cast-in-place concrete surface layers are suitable for heavy equipment areas, but are less flexible and more difficult to wire and maintain later compared to raised modular floors. Both require moisture-proof treatment and long-term monitoring under humid conditions.
Installation Specifications and Acceptance Criteria (Applicable in Shanghai)
The installation process must comply with national and industry standards (relevant GB specifications, IEC, and TIA reference standards), as well as meet the local fire safety and building management requirements of Shanghai. Key acceptance criteria include levelness, static and dynamic load testing, continuity of anti-static grounding, sealing of board joints, certification of fire resistance ratings, as well as the provision and labeling of cable management channels.
Procurement Process and Technical Comparison Recommendation
It is recommended to first prepare a technical specification during procurement, clearly defining load indicators, module dimensions, and requirements for anti-static and fire protection ； Compare samples with suppliers and conduct on-site sample testing ； The contract specifies warranty, third-party inspection, and maintenance response period. Considering the product characteristics of German Melue flooring, evaluate its suitability for the Shanghai data center project as well as its after-sales support capabilities.
Summary and Suggestions
Summary: Computer room floor selection should comprehensively consider load capacity, heat dissipation, cabling, fire prevention, and anti-static capabilities, and must be strictly accepted in accordance with relevant Shanghai regulations. German Merlu flooring can be an option, but purchasing decisions should be based on technical specifications, third-party certifications, and local support services to ensure reliable long-term performance and easy maintenance.
