The Chayora Taicang facility, with its near-Shanghai location and high-standard construction, serves as a critical computing hub supporting Pinduoduo’s high-reliability, low-latency operational requirements.
Project Requirements and Challenges · Stringent Demands Placed on the Floor System by a Data Center Environment
As an international Class-A data center serving large internet enterprises like Pinduoduo, the Phase III data center imposed technical requirements on the floor system that far exceeded those of ordinary construction projects. The high-density IT equipment operating 24/7 within the facility, the complex integrated cabling layout, and the frequent maintenance needs all demanded that the floor system simultaneously meet rigorous standards across multiple dimensions, including electrostatic protection, load capacity, ventilation and cooling, and operational maintainability.
?① Electrostatic Protection and Grounding for High-Density IT Equipment
The data center houses a large number of precision electronic devices, including servers, switches, and storage units, deployed at high rack density with significant asset value. Electrostatic discharge (ESD) can cause chip damage, data loss, or equipment failure. The floor must therefore deliver reliable and continuously stable anti-static performance, with surface resistance strictly controlled within the 10⁶ to 10⁹ Ω range. The entire floor system must also maintain effective grounding continuity, channeling static electricity safely into the ground to provide a protective barrier for all precision equipment.
?② High Load Capacity to Support Server Racks and Heavy Equipment
A fully loaded server rack in a data center can exceed one metric ton, and the concentrated placement of UPS systems, precision air conditioning units, and other heavy ancillary equipment places demanding requirements on both the point load and uniformly distributed load capacity of the floor system. The raised access floor must maintain structural integrity and planar stability under the combined effects of sustained static loads and frequent dynamic loads, with no sagging, deformation, or noise.
?③ Precision Underfloor Air Distribution and Cooling
Data centers typically employ an “underfloor supply, overhead return” airflow management approach, in which the plenum space beneath the raised floor serves as the static pressure chamber for the precision air conditioning system. This requires the floor system to support adjustable raised heights sufficient for airflow distribution, while the sealing characteristics of the floor panels and the placement of air grilles must be precisely coordinated to ensure cold air is evenly delivered to the front of every rack row, maintaining a stable temperature and humidity environment throughout the facility.
?④ Comprehensive Cable Routing and Management for High-Density Wiring
The data center involves the integrated routing of high-speed fiber optic cables, high-power electrical cables, monitoring signal cables, and other conduits at densities far exceeding those found in ordinary office environments. The raised access floor system must provide ample, well-organized cable routing space for all these runs, while enabling maintenance personnel to quickly locate, adjust, add, or remove cables without disrupting normal equipment operations.
?⑤ Reliable Panel Restoration Following Frequent Maintenance Access
Electrical, network, HVAC, and other maintenance activities take place with high frequency in a live data center environment. Each maintenance event typically requires the removal of several floor panels to access the underfloor plenum. During repeated panel removal and reinstatement, the support pedestal system is vulnerable to displacement or rotation from incidental contact. Once pedestals shift out of position, panels become difficult to reseat precisely, in minor cases causing uneven panel gaps or slight surface undulation, and in serious cases requiring large-scale re-leveling of the entire pedestal grid. This represents a critical challenge that data center floor installations must resolve.
?⑥ Class-A Fire Rating and Green Environmental Requirements
As a critical infrastructure facility carrying enormous data assets, the data center demands strict fire safety compliance. All construction materials within the facility must meet Class-A non-combustible or high fire-resistance standards. In addition, as a fully sealed operational environment with enclosed air circulation, any formaldehyde or harmful volatile emissions will directly affect the long-term safety of equipment and the health of maintenance personnel. The environmental performance of the floor system and all ancillary materials must therefore meet rigorous standards.
Based on the above six professional requirements, and after careful product comparison and technical solution demonstration, this project finally selected Huiya CSL1000 calcium sulfate antistatic raised floor as the core floor system, and paired it with Japanese Konishi KU928 F4 star bracket professional adhesive as auxiliary material, providing a comprehensive, reliable and environmentally friendly raised floor solution for the third phase of the Chaoyang Asia-Pacific Warehouse Data Center.

?Why Do Data Center Machine Rooms Require KONISHI KU928 Pedestal Adhesive?
The specialized operational demands of high-density equipment in a data center mean that ongoing cross-trade maintenance activities will take place continuously throughout the facility’s service life – encompassing network cabling adjustments, high-voltage electrical modifications, precision air conditioning refrigerant circuit servicing, UPS system maintenance, fire suppression system inspections, and more.
Each maintenance event typically requires the removal of a number of floor panels to temporarily open floor access and work within the underfloor plenum. Under conventional installation methods where pedestals are not adhesively fixed, once panels are removed, the steel support bases, no longer held in compression by panel weight, are prone to displacement or rotation as personnel move through the underfloor space.
Once a pedestal shifts out of position, the consequences are frustrating: panels cannot be accurately returned to their original positions, resulting at best in uneven panel gaps or slight surface irregularity, and at worst requiring large-scale re-leveling of the entire support grid. This is not only time-consuming and labor-intensive, but during emergency repair scenarios can delay service restoration and compromise the continuous operation of the facility.
⚠️ Pain Points in Data Center Maintenance: After multiple maintenance checks, accumulated misalignment in the raised floor support system of a data center not only complicates floor restoration but can also cause minor vibrations or noises due to uneven surfaces, affecting the quiet operating environment of the data center and potentially interfering with the precision equipment beneath the server racks.
To address these pain points, after all floor installation and leveling were completed, the project team deployed workers to the raised floor to apply Xiaoxi KU928 bracket-specific adhesive to all fixing screw holes and contact surfaces of the support bases. After application, the adhesive was allowed to cure at room temperature for 24 hours, ensuring a stable bond between the support bases and the floor substrate, thus locking the entire support system in precise position.
✅ Practical Application Results: After the comprehensive application of Xiaoxi KU928 bracket adhesive in the Taicang Chaoya Phase III project, the entire 2000-square-meter server room floor support base system was securely locked in place. The on-site construction team reported that the KU928 adhesive was smooth to apply, easy to use, and cured evenly and stably, with excellent bonding performance verified on-site. During subsequent maintenance by various trades in the server room, the bracket positions remained stable after panel removal, and the floor restoration work was smooth and efficient. This effectively reduced the disturbance to the overall stability of the floor system caused by multiple maintenance operations, significantly improving the maintainability and ease of operation of the server room.
? Process Highlights: After the floor installation was completed, the construction team specifically arranged for workers to enter the raised floor and meticulously apply adhesive to each support base hole. This demonstrates the project’s high attention to detail in engineering quality and is a concrete manifestation of Huiya Flooring’s adherence to professional construction standards in data center projects. It is worthy of promotion and application in similar server room projects.
Konishi KU928 bracket adhesive meets the F4 star (F☆☆☆☆) environmental certification standard—the strictest level for formaldehyde emission control in the Japanese JIS building materials standard system. This indicates extremely low formaldehyde emissions, and the product has passed limit tests for 13 harmful substances, meeting the safety requirements for building materials used in enclosed indoor environments. Data centers are long-term closed indoor environments; using F4 star certified construction materials helps maintain air quality and ensures the health and safety of equipment and maintenance personnel.
