🔸 1. Flatness Challenge of Large-Area Continuous Installation

The 5,500-square-meter Phase II construction area spans multiple functional zones (open offices, meeting rooms, archive rooms, tea break areas, restrooms, etc.). According to the on-site color floor plan, different zones must interface with various surface materials—including Dream Color wall tiles, Mirage PVC, Pearland Vista PVC, Gratisland LVT wood-grain, and Summerfield Oak flooring, with specifications including 25cm×100cm, 22.86cm×91.44cm, 23cm×150cm, etc. The finished floor height must maintain flatness within ±0.5mm across the entire floor to ensure seamless transitions between multiple surface materials.

🔸 2. Load-Bearing Demands of Smart Equipment and Heavy Workstations

The Phase II factory area integrates a higher density of smart manufacturing equipment, automated production line monitoring terminals, and high-density workstations. Some areas must withstand the repeated forces of heavy mobile equipment, requiring the raised access floor system to demonstrate stable concentrated load capacity and impact resistance.

🔸 3. German-Standard Fire Safety, Anti-Static and Green Environmental Requirements

As a German multinational, Siemens enforces near-stringent internal control standards for the environmental performance, fire rating, and VOC emissions of building materials. The raised access floor must meet zero-formaldehyde, zero-radiation, and Class A fire ratings, while maintaining stable performance over long-term use.

🔸 4. Schedule Pressure of Concurrent Construction and Delivery

Some areas of the Phase II factory had already entered the equipment installation and commissioning phase. The raised access floor installation had to be carried out in coordination with mechanical, electrical, HVAC, and low-voltage trades, demanding strong on-site coordination and milestone control capabilities from the project team.

✅ Innovative Six-Sided Encapsulation Structure
The ECS1000 features a high-density calcium sulphate panel as its core substrate, fully encapsulated on all six sides with galvanized steel and treated with anti-rust clear coating. This structure combines the high strength, fire resistance, and sound insulation properties of calcium sulphate with the impact and corrosion resistance of steel, fundamentally eliminating the traditional drawbacks of raised access floors—edge chipping and moisture-induced deformation.

✅ Outstanding Load Capacity
Uniformly distributed load reaches 18.0 kN/m², with a concentrated load of 4.5 kN, satisfying the high-intensity application requirements of smart equipment and automation production lines.

✅ Superior Fire Performance
Under flame exposure, the ECS1000 produces no toxic gases, complying with China’s Class A fire rating standards. This is a critical safety guarantee for the Siemens factory environment, where electrical components and automation control equipment are densely deployed.

✅ Green Environmental Certification
The ECS1000 product is zero-formaldehyde and zero-radiation, complying with national green building material standards and EU environmental directives, perfectly aligning with Siemens’ demands for environmental control in its factory environments.

✅ Modular Maintainability
The modular pedestal-and-panel combination allows any single floor panel to be lifted independently, facilitating future inspection and expansion of underfloor utilities, power and data trays, and HVAC ducts—greatly enhancing the smart factory’s future flexibility for renovation.

✅ Moisture Stability
The six-sided steel encapsulation effectively blocks moisture penetration, allowing the ECS1000 to maintain long-term dimensional stability even under Wuxi’s rainy and humid climate conditions.

🎯 Solution to Challenge 1: ±0.25mm Precision Conquers Multi-Surface Flatness

For the multi-zone, multi-surface interface challenges of Phase II, the ECS1000 provides foundational precision with ±0.25mm dimensional tolerance and ±0.5mm diagonal flatness. Before installation, HUIYA engineers used the Phase I finished surface as the benchmark, deploying laser levels for full-floor multi-point layout measurements, and individually fine-tuned each pedestal through millimeter-level height-adjustable mechanisms.

For the five different thicknesses of surface materials shown on the color floor plan (60×60cm ceramic tile, 25×100cm Mirage PVC, 22.86×91.44cm Pearland Vista, 23×150cm Gratisland LVT wood-grain, Summerfield Oak flooring, etc.), HUIYA coordinated thickness data with each surface material supplier in advance and dynamically adjusted pedestal reserve heights across different zones. As a result, the cross-zone elevation differences after final installation were controlled within visually imperceptible ranges, perfectly achieving seamless transitions across multiple materials.

🎯 Solution to Challenge 2: Six-Sided Steel Encapsulation Handles 18.0 kN/m² Load with Ease

Faced with the load pressures of smart equipment and heavy mobile workstations, the ECS1000’s composite structure—six-sided galvanized steel encapsulation combined with 1,600 kg/m³ high-density calcium sulphate substrate—demonstrated outstanding load-bearing capacity:

• Uniformly distributed load of 18.0 kN/m² – Stably supports long-term static loads from high-density workstations and automation control cabinets;
• Concentrated load of 4.5 kN – Sufficient to handle dynamic pressures from equipment movement, AGV passage, and concentrated maintenance tool actions;
• Six-sided steel encapsulation – Completely eliminates the risk of edge chipping and damage common to traditional calcium sulphate panels, ensuring each panel maintains structural integrity throughout long-term use.

Combined with steel adjustable pedestals (height range 55mm – 2,000mm; 150mm used in this project), the entire system forms a stable “panel + pedestal” load-bearing unit with uniform load distribution and zero risk of localized settlement—fully matching Siemens’ future smart factory equipment upgrade and expansion needs.

🎯 Solution to Challenge 3: Class A Fire Rating + Zero Formaldehyde Meets Stringent German-Invested Environmental Controls

The ECS1000’s performance in fire safety and environmental protection precisely aligns with Siemens’ rigorous internal control standards as a German enterprise:

Fire Performance: The calcium sulphate substrate is inherently non-combustible, producing no toxic gases under flame exposure, and complies with China’s Class A fire rating. This provides fundamental fire safety protection for the Siemens factory environment, where electrical components and automation control equipment are densely deployed.

Environmental Performance: The product features zero formaldehyde emissions and zero radioactive substances, complying with national green building material standards and EU environmental directives (REACH/RoHS).

Auxiliary Construction Materials Equally Upgraded: Pedestal bonding uses Japanese Konishi KU928 polyurethane adhesive, which meets the highest JIS A 5536 F★★★★ environmental rating—containing no VOCs or harmful components restricted by Japan’s Ministry of Health, Labour and Welfare—non-toxic and odorless. This forms a complete environmental closed-loop from product to auxiliary materials.

This combined solution enabled the ECS1000 to successfully pass Siemens’ global building material internal control audit (SGRE Material Compliance), laying a compliance foundation for HUIYA’s future engagement with more German-invested projects.

🎯 Solution to Challenge 4: Modular System + Mature Project Management Handles Concurrent Schedules with Ease

The Phase II project involved numerous concurrent construction nodes with mechanical, electrical, HVAC, and low-voltage systems. HUIYA achieved efficient coordination through dual-engine drive of “product modularity + management standardization”:

• Product Modularity: The 600×600mm standard panel units can be installed and removed independently, allowing flexible adjustment of work sequences in any area based on the construction progress of other trades. The reasonable single-panel weight of 18.5 kg also maximizes on-site manual handling efficiency;
• Standardized Construction Process: HUIYA adopted the “central axis positioning + inside-out radiating installation” methodology, with stable and controllable daily progress;
• Digitalized Progress Synchronization: On-site construction management adopted digital process tracking, with daily progress, material consumption, and quality milestones synchronized in real time with the Siemens client team and general contractor, ensuring transparent information across all parties during concurrent operations;
• Long-Term Maintainability: Each panel can be lifted independently, making future inspection and expansion of underfloor utilities, power and data trays, and HVAC ducts highly convenient,substantially reducing the lifecycle operation and maintenance costs of the Siemens factory.

▶ 1. Substantive Recognition of Product Strength by Top-Tier International Industrial Clients

Through thousands of operational hours during Phase I at Siemens, the ECS1000 demonstrated stable performance across load-bearing, fire safety, moisture resistance, and environmental indicators—the most persuasive “field certification” of HUIYA’s product technology system. The Phase II contract renewal signifies that HUIYA’s raised access floor has officially entered the Approved Vendor List (AVL) of a German multinational.

▶ 2. A Key Gateway into the European-Invested Manufacturing Market

German enterprises wield far-reaching influence in China’s and the world’s manufacturing supply chains. Leveraging the Siemens project as a benchmark case, HUIYA can use the success story of an international client as powerful endorsement when expanding into German and European-invested enterprises such as Bosch, BASF, Mercedes-Benz, and ZF—substantially shortening the trust-building cycle with new clients.
