From Raised Access Floors To Structural Ceiling Systems: Huilian Creates Integrated Data Center Space Solutions

With the rapid development of data centers, smart manufacturing facilities, and cleanroom environments, modern buildings are facing increasingly complex infrastructure challenges.

Inside today’s data centers, the number of IT devices, power systems, communication cables, and mechanical pipelines continues to grow. Traditional suspended ceilings were mainly designed for appearance and basic finishing. However, modern data center environments require much more:

• Reliable structural support

• Efficient installation and maintenance

• Long-term operational stability

• Flexible space management

In practical applications, the space above the ceiling often accommodates various systems, including:

• Electrical cable trays

• Fire protection pipelines

• HVAC duct systems

• Mechanical and auxiliary equipment

If the ceiling structure lacks sufficient strength and stability, it may affect equipment installation, increase maintenance difficulties, and create potential operational risks.

To meet these requirements, Jiangsu Huilian Access Floor Co., Ltd. has developed the Huilian Aluminum Structural Ceiling Grid System, based on more than 20 years of experience in raised access floor research, manufacturing, and engineering applications.

The system adopts a fully aluminum modular framework with standardized profiles, precision connection nodes, and tested load-bearing performance. It provides a reliable overhead infrastructure solution for:

• Data centers

• Cleanrooms

• Financial technology facilities

• Intelligent manufacturing plants

• High-performance industrial buildings

Fully Aluminum Modular Structure for Complex Spaces

The Huilian Structural Ceiling Grid System uses specially designed aluminum alloy extrusion profiles as the primary load-bearing components.

The complete structure consists of:

• Main beams

• Secondary beams

• Auxiliary lightweight beams

• Perimeter beams

• Aluminum die-cast connectors

Compared with traditional lightweight steel keel systems, aluminum structural ceilings offer significant advantages:

For data centers, ceiling systems are expected to operate continuously for many years. Equipment upgrades, cable adjustments, and maintenance activities are frequent.

Therefore, a modern ceiling system must not only meet initial installation requirements but also support long-term operation and future flexibility.

Multiple Grid Layout Options for Different Project Requirements

Different projects have different ceiling panel sizes, load requirements, and spatial layouts.

To meet diverse engineering needs, Huilian provides multiple modular grid configurations:

Among these options, the 1200mm × 600mm modular grid system is widely adopted in data center projects because it matches standard ceiling panel dimensions while allowing convenient future maintenance and replacement.

Structural Design: A Ceiling System Designed for Load-Bearing Performance

Traditional ceilings mainly focus on surface appearance. Structural ceiling systems focus on overall load distribution and mechanical stability.

The Huilian system creates a modular grid structure through the combination of main beams and secondary beams, allowing loads to be evenly transferred to the building structure.

Main Components Include:

Main Beam

Manufactured from high-strength aluminum alloy profiles, the main beam carries the primary longitudinal load and serves as the core structural component of the ceiling system.

Secondary Beam

The secondary beam connects with the main beam to create a stable grid structure, improving overall rigidity while providing convenient support for ceiling panels.

Lightweight Auxiliary Beam

Used for local grid reinforcement, improving installation flexibility in smaller or special-shaped areas.

Perimeter Beam

Installed around wall edges to provide finishing support and enhance overall ceiling stability.

Tested Load Performance Ensures Data Center Reliability

For special environments such as data centers and server rooms, the key requirement of a ceiling system is not only appearance, but also structural safety and long-term reliability.

Huilian has conducted multiple mechanical performance tests, covering:

• Individual beam strength

• Connection node performance

• Complete modular grid structure verification

For the standard 1200mm × 600mm grid system, the tested performance includes:

• ndividual main and secondary beams have also been tested with higher load capacity:

• Rated concentrated load: 4.4kN (approx. 448kg)

• Rated distributed load: 6.1kN/m² (approx. 611kg/m²)

• Maximum tensile force of clip connection nodes: 1233.8kgf

These test results demonstrate that Huilian’s structural ceiling system can support not only conventional ceiling installations but also various overhead infrastructure systems commonly found in modern data centers:

• Cable trays

• Fire protection pipelines

• HVAC ductwork

• Mechanical auxiliary equipment

A reliable overhead load-bearing structure helps reduce future modification risks and improves the long-term stability of critical facility operations.

Precision Connection System Improves Structural Stability and Installation Efficiency

Besides the strength of the ceiling profiles themselves, connection nodes are one of the most important factors determining the reliability of a structural ceiling system.

The Huilian Structural Ceiling Grid System adopts an aluminum die-cast connector system. Through standardized connection design, beams in different directions can be accurately assembled, creating a complete load-bearing network.

The system mainly uses three types of connectors:

All connectors are manufactured through aluminum die-casting technology and precisely matched with the aluminum extrusion profiles.

Compared with traditional on-site cutting and welding methods, modular connection technology provides clear advantages:

l Reduced on-site processing work

l Improved installation accuracy

l Shortened construction time

l Reduced human installation errors

For large-scale data center projects, standardized installation methods significantly improve construction efficiency while also making future partial dismantling, expansion, and maintenance easier.

Flexible Suspension Design for Different Building Structures

A reliable ceiling system requires not only strong structural components but also a flexible suspension solution that can adapt to different building conditions.

The Huilian Structural Ceiling System uses M10 suspension rods connected to the main building structure, with turnbuckles allowing precise height adjustment.

The standard suspension system includes:

Turnbuckle

Used for fine adjustment of installation height, ensuring accurate ceiling leveling.

Locking Nut

Maintains structural stability after height adjustment.

Connection Components

Transfer loads between the ceiling structure and the building framework.

The standard suspension points are arranged at 1.2m × 1.2m spacing, with approximately 0.89 suspension rod assemblies installed per square meter, ensuring uniform load distribution throughout the ceiling system.

Adaptable Edge Solutions for Different Wall Structures

Different construction environments require different installation methods.

Huilian provides customized edge connection solutions:

Concrete Walls and Brick Walls

The system adopts perimeter beam suspension methods to improve overall structural stability.

Lightweight Walls Such as Gypsum Board Partitions

Lightweight beam fixing methods are used to simplify installation and reduce construction complexity.

This flexible design allows the structural ceiling system to adapt to different building types and site conditions.
