In modern office spaces, raised access floors are far more than just “a panel beneath your feet.” They bear the daily weight of foot traffic, material transport, and equipment handling, serving as the foundational support for spatial operations and an invisible benchmark for measuring the quality and reliability of an office environment. However, the load-bearing performance of flooring is often quietly consumed in places “out of sight” – it is only when deformation, sinking, and joint misalignment surface that people realize: the rationality of product selection determines how far a floor panel can truly go.

Walkways, as the most densely trafficked routes for both personnel and material flow within an office space, are precisely where load pressure is most concentrated, yet most easily underestimated. When water delivery carts roll back and forth day after day, and when furniture and equipment are repeatedly relocated, raised access floors of ordinary load-bearing grades will gradually approach their performance threshold under cumulative loads, ultimately issuing an “overload warning” in the form of deformation.

The secondary repair and upgrade of the walkway raised access floor at the TEL (Tokyo Electron) Wuxi Branch Office is a textbook case of exactly this scenario. The question it sought to answer was not merely “how to repair the deformed floor,” but rather “how to make the walkway floor truly match the real operating conditions it must endure.” Rather than opting for a simple like-for-like replacement, HUIYA approached the issue from the root cause of the load, completing a forward-looking load-bearing upgrade with the HUIYA SC1000 Steel Raised Access Floor.

1. The Client: TEL (Tokyo Electron) Wuxi Branch

The client for this project, TEL (Tokyo Electron) Co., Ltd., is a subsidiary of Tokyo Electron Limited (TEL). Tokyo Electron is one of the world’s leading suppliers of semiconductor manufacturing equipment and flat panel display (FPD) manufacturing equipment, with its business covering core front-end semiconductor processes, including wafer coating and developing, etching, thin-film deposition, and cleaning. It has long served the global integrated circuit manufacturing supply chain.

TEL operates multiple branches across China, providing equipment sales, technical support, after-sales service, and spare parts supply for local semiconductor manufacturers. The Wuxi Branch Office is located in the IC Design Building in Xinwu District, Wuxi – a location with distinct industrial significance.

Xinwu District in Wuxi is one of China’s most important clusters for the integrated circuit industry, and the IC Design Tower hosts a large concentration of IC design firms, semiconductor equipment companies, and supporting service providers. By establishing its Wuxi branch here, TEL is well-positioned to stay close to clients and rapidly respond to the technical and service needs of semiconductor manufacturers in the region.

Precisely because the industry in which the client operates places high implicit demands on the stability, professionalism, and reliability of its office environment, this raised access floor repair and upgrade was by no means an ordinary floor renovation, it was a critical project directly tied to the client’s daily operational order and overall spatial quality.

2. Project Background: Cause Analysis of Walkway Deformation After Two Years of Use

After approximately two years of use, the raised access floor in the public walkway area of the TEL Wuxi Branch Office began showing noticeable signs of deformation. Upon receiving the request, the HUIYA technical team immediately conducted a detailed on-site inspection and root cause analysis.

The diagnosis revealed that the walkway deformation was not caused by any isolated product defect, but rather was the typical result of cumulative long-term heavy-load operating conditions. Specific contributing factors included:

As the most densely trafficked route for both personnel and material flow within the office space, the walkway actually bears load intensities far exceeding those of ordinary workstation zones. The load-bearing grade of the original raised access floor gradually reached its performance threshold under two years of high-intensity heavy-load conditions, ultimately manifesting as surface deformation, joint misalignment, and localized sinking.

Based on this assessment, TEL explicitly requested a replacement of the walkway area and proactively inquired: Was there a raised access floor product with superior load-bearing performance that could fundamentally solve the recurring deformation problem?

3. Requirements: Why Must Walkway Areas Use Higher Load-Bearing SC-Series Raised Access Floors?

To solve “recurring deformation,” the key lies in ensuring that the product’s load capacity matches or even exceeds, the actual operational demands. The HUIYA technical team systematically broke down the walkway load characteristics and identified three core categories of load sources:

Load Type	Source Scenario	Stress Characteristics	Demand on the Floor
Pedestrian Load	Daily personnel movement	High-frequency, continuous, distributed	Stability under long-term cyclic loading
Concentrated Load	Equipment and furniture relocation	Instantaneous, concentrated, point-form	Resistance to concentrated point loads and impact
Rolling Load	Water carts, trolley transport	Dynamic, repetitive, linear	Resistance to rolling fatigue and panel deformation

Among these three load types, rolling loads and concentrated loads are the primary causes of walkway deformation. Under prolonged rolling pressure, the internal structure of ordinary load-grade raised access floor panels easily accumulates fatigue damage, ultimately resulting in irreversible plastic deformation.

Therefore, for heavy-load traffic zones such as walkways, it is essential to select higher load-grade SC-series steel raised access floors, establishing sufficient load-bearing redundancy at the product level to avoid the cycle of “repair, fail, repair again.”

4. Product Selection: Why Recommend the HUIYA SC1000 Steel Raised Access Floor?

For the heavy-load conditions of the TEL walkway, HUIYA recommended the HUIYA SC1000 Steel Raised Access Floor as the upgrade replacement solution.

1. Current State of Industry Load-Bearing Grades: From SC668 to SC1000

In a large number of office and data center projects in China, the SC668-grade steel raised access floor is the most commonly used. This grade may suffice in ordinary office workstation zones, but in walkways, equipment corridors, and other heavy-load scenarios, its load-bearing redundancy is often insufficient, leading to deformation over time.

HUIYA, in its product configuration philosophy, starts at the SC800 grade as a baseline and offers higher load-grade products such as SC1000 for heavy-load applications. This “high-baseline” selection logic is designed precisely to reserve ample load-bearing safety margins for clients from the outset.

2. Advantages of HUIYA SC1000 Over Standard SC668

Comparison Dimension	Standard SC668	HUIYA SC1000
Load Positioning	Ordinary office workstation zones	Heavy-load walkways, equipment corridors, logistics routes
Concentrated Load Capacity	Baseline level	Significantly enhanced, better suited for relocation point loads
Rolling Fatigue Resistance	Average	Superior, accommodates repeated water cart and trolley rolling
Structural Strength	Standard steel structure	Reinforced steel structure with thicker plates and superior welding
Long-Term Stability	Prone to fatigue under heavy loads	Significantly reduced deformation risk under heavy loads
Suitable Scenarios	Ordinary office zones	Critical routes with frequent relocation and heavy traffic

3. Structural and Performance Logic of SC1000

The HUIYA SC1000 adopts a fully welded steel composite structure: upper and lower steel plates are spot-welded into shape, with the interior filled with high-strength foamed cement, forming an integrated “steel–core–steel” load-bearing system.

By upgrading the walkway area from the original grade to SC1000, this “heavy-load route” was equipped with load-bearing capacity that genuinely matches its actual loading, fundamentally addressing TEL’s demand for “better load-bearing performance.”

5. Construction Implementation: Efficient 3-Day Completion with Smooth Operational Transition

Construction for this repair began on May 3, 2026, and was completed on May 5, 2026, spanning 3 days and covering approximately 110㎡ of the walkway area. Given that the client’s office space remained in normal use, the HUIYA construction team developed an installation plan emphasizing minimal disruption and orderly progression.

1️⃣Old Panel Removal and Condition Assessment
The deformed panels were systematically removed, while the extent of deformation and the condition of the substrate support system were simultaneously evaluated to provide a basis for subsequent leveling.

2️⃣Support System Inspection and Substrate Leveling
The original pedestal support structure was inspected, with support height and levelness re-verified and corrected to ensure a flat baseline for the new panel installation.

3️⃣Panel-by-Panel Precision Installation of SC1000
SC1000 steel raised access floor panels were laid panel by panel along the walkway traffic direction, with strict control over joint flatness and assembly precision to ensure uniform load distribution.

4️⃣Wood-Grain Surface Style Restoration
The post-repair floor surface continued the original wood-grain style of the office area, maintaining visual consistency with the existing space and preventing any obvious visual disconnect in the repaired zone.

5️⃣On-Site Safety and Civilized Construction Management
Safety signage was installed in the construction zone, tools were properly arranged, cables were managed in an orderly manner, and the impact on surrounding office personnel was minimized to the greatest extent possible.

Upon completion, the walkway was flat and stable, visually consistent with the original space style, and its load-bearing capacity was substantially enhanced—better suited to accommodate the long-term heavy-load traffic and relocation needs of the area.

6. Project Value: Long-Term Benefits for the Client

The significance of this upgrade extends well beyond “repairing the deformed floor”—it establishes a future-ready load-bearing guarantee for the office environment of TEL Wuxi Branch. The specific benefits are reflected in the following aspects:

✅1. Reduced Cost and Frequency of Future Repeated Repairs

By upgrading the walkway to the high-load SC1000 raised floor product, ample load-bearing redundancy is established at the product level, effectively reducing the risk of re-deformation caused by heavy loads, lowering potential future secondary or tertiary repair costs, and avoiding the disruption that repeated construction would cause to office operations.

✅2. Ensured Smoothness and Safety of Daily Logistics Routes

A flat and stable walkway surface allows daily operations, such as water cart delivery, trolley material transport, and equipment relocation, to proceed more smoothly. It also reduces safety hazards arising from floor deformation and joint height differences, providing a safer environment for daily employee movement.

✅3. Enhanced Overall Office Quality and Professional Image

As a professional service organization in the semiconductor equipment field, TEL Wuxi Branch frequently hosts client visits and technical exchanges. A flat, aesthetically pleasing, and stylistically unified walkway environment helps preserve the professional quality of the office space and the corporate image.

✅4. Convenience for Future Spatial Operation and Maintenance

The modular installation method of SC1000 facilitates future cable routing, equipment relocation, and localized maintenance, leaving room for the client’s future spatial flexibility and operational management.

✅5. Establishing Selection Experience Based on Real Operating Conditions

This project also accumulated valuable practical experience for the client in “differentiated selection based on zone-specific operating conditions” using high-load products in heavy-load areas like walkways and equipment rooms, and standard configurations in ordinary workstation zones, achieving a more rational balance between performance and investment, while providing a reference for future construction and renovation of other spaces.

---

The TEL Wuxi Branch walkway raised access floor secondary repair and upgrade project stands as a textbook example of “load-bearing upgrades targeting real operating conditions.” It clearly validates the product selection philosophy HUIYA has consistently championed:

The selection of raised access floors must match real-world usage scenarios; heavy-load routes such as walkways and equipment corridors deserve to be configured with load-bearing grades commensurate with their demands.

Faced with the client’s frustration over “walkway deformation after two years of use,” HUIYA did not settle for a simple “like-for-like replacement.” Instead, we approached the issue from the root cause of the load, recommended the higher-performing HUIYA SC1000 Steel Raised Access Floor, and completed a smooth transition with 3 days of efficient construction—solving the immediate deformation issue while establishing a long-term load-bearing guarantee for the client’s ongoing office operations.
