I. Definition and Common Names of Raised Floors

A raised floor (Raised Floor) is a modular flooring system that is erected above the original structural floor of a building through an adjustable support system. It is also known as a movable floor, elevated floor, or raised metal flooring (Raised Metal Flooring). Its core function is to provide a concealed space for cable management inside the building, while meeting the requirements for floor bearing capacity, fire protection, anti-static properties, and other functions in different scenarios.

In the industrial and commercial fields, raised metal flooring (such as ZIli's OA600 steel cement floor) has become the preferred solution for scenarios like data centers and smart office buildings due to its high strength, durability, and flexible cabling capabilities.

II. Structure and Core Components of Raised Floors

A complete raised floor system consists of the following parts:

• Panel: Usually made of a steel structure (such as ZIli's OA600 steel cement panel), filled with lightweight concrete or cement inside, and covered with an anti-static or fireproof coating on the surface.

• Support System: Includes adjustable-height zinc steel alloy supports and crossbeams, providing stable support and adapting to uneven floors.

• Auxiliary Accessories: Such as edge covers, ventilation panels, etc., are used to optimize space sealing and air flow management.

  
  

• Taking ZIli's steel cement movable floor as an example, its panel is manufactured through the stretching, forming, and welding process, and filled with aerated cement inside. It has the characteristics of light weight and high strength, and is suitable for international standard sizes such as 600mm×600mm or 610mm×610mm.

VIII. Raised Metal Flooring vs. Traditional Flooring: A Comparative Analysis

When selecting a flooring system, understanding the differences between raised metal flooring and traditional flooring is crucial. Traditional floors (concrete, tile, carpet, etc.) are installed directly on the structural slab, while raised metal flooring creates an accessible void above the slab through an adjustable support system.

Application Recommendations:
Choose raised metal flooring for data centers, server rooms, smart office buildings, laboratories, and modern workspaces that require frequent reconfiguration.
Choose traditional flooring for residential buildings, low‑rise offices, warehouses, and spaces with minimal cabling or HVAC needs.

For modern commercial and technological facilities, although raised metal flooring has a higher initial cost, its long‑term flexibility, maintenance convenience, and energy efficiency give it a lower total cost of ownership (TCO).

IX. Cost Factors and Budget Planning for Raised Metal Flooring

The total cost of raised metal flooring is determined by multiple factors. Proper planning can effectively control your budget.

1. Core Panel Material (Largest Cost Driver)

2. Surface Finish

3. Understructure (Pedestals and Stringers)
Pedestal and stringer systems account for 15%–25% of the total system cost. The higher the finished floor height (FFH), the higher the cost – for example, a 1000mm FFH requires thicker steel tubes and additional bracing.

4. Transportation and Logistics
International shipping can represent 10%–30% of the total landed cost. Steel panels are dense – one 20GP container can hold approximately 500–600 m²; calcium sulfate panels are heavier, so weight limits are reached before the container is full, increasing unit shipping costs.

Budget Planning Tips:
- Define load requirements early to avoid over‑specification waste.
- Reserve 10%–15% spare panels for future replacements.
- For international orders, pay attention to packaging (wooden crates are essential for fragile finishes).
- New‑build projects are usually more cost‑effective than retrofits, which often incur higher labor costs.

X. Energy Efficiency and Underfloor Air Distribution (UFAD)

Raised metal flooring not only provides cable management space but can also significantly improve building energy performance.

How UFAD Works:
The underfloor void can serve as a supply air plenum. Cool air is delivered through perforated floor panels directly into the occupied zone. Because cool air naturally rises, it leverages thermal stratification to cool the space efficiently.

Key Energy Benefits:

• Cool only the occupied zone – typically the first 1.8m (6 ft) above the floor

• Higher supply air temperatures – cool air can be delivered directly without mixing, allowing temperatures up to 10°F higher than conventional HVAC

• Lower fan energy – low‑velocity air delivery reduces fan power consumption

• Reduced heat loss – insulation under the raised floor prevents energy waste

• Lower ceiling plenum requirements – less space needed for large ductwork

Quantified Savings:
- UFAD systems can reduce annual HVAC energy consumption by 16–27% compared to traditional overhead mixing systems.
- In data centers, cooling energy savings can reach 24–66%.
- Peak month savings of 37–39% have been recorded, with up to 51% in October.

Requirements for Raised Metal Flooring:
- Must be equipped with perforated panels – open area typically ranging from 25% to 68% depending on rack density.
- Adequate floor height (usually 150–600mm) to ensure uniform airflow distribution.
- Good sealing to prevent air leakage.

Choosing a raised metal flooring system with UFAD capability can significantly reduce operational energy costs and support green building and sustainability goals.

XI. International Standards and Compliance

Raised metal flooring must comply with different national and regional standards to ensure safety, performance, and compatibility.

Major Standard Systems:

CISCA Load Grade Reference:
- Light Load: General offices
- Medium Load: General commercial spaces
- Heavy Load: Heavy equipment areas
- Truss Load: Data centers and extreme load‑bearing applications

Key Factors for Standard Selection:
1. Project location – decisive factor: Europe uses EN, North America uses CISCA/ASTM, China uses GB.
2. End use – offices typically choose Light/Medium, data centers choose Heavy/Truss with ESD focus.
3. Local regulations – must meet building codes, fire safety, and electrical safety requirements.

ZIli products have passed safety tests in multiple countries and hold ISO 9001 quality certification, ensuring compliance with international standards.

XII. Installation Best Practices

Proper installation is critical to the long‑term performance of raised metal flooring.

Pre‑Installation Preparation:
1. Design & Engineering: Define load requirements (standard office: 300–500 kg/m²; data center: 1,000–1,500 kg/m²); determine floor height (150mm for basic cabling, 1000mm for large HVAC ducts).
2. Site Preparation: Ensure subfloor flatness ≤3mm/m²; control humidity below 60% to prevent corrosion; mark existing utility locations to avoid conflicts.

Installation Steps:
1. Layout & Marking: Use laser level to mark pedestal grid lines; standard grid 1200×1200mm, high‑load areas may require 600×600mm.
2. Install Pedestals & Stringers: Fix adjustable pedestals with anchor bolts or epoxy adhesive; rotate threaded studs to adjust height, lock with torque wrench (10–15 Nm); install stringers to form a rigid grid.
3. Panel Placement: Start from a corner and lay full panels; cut edge panels using appropriate tools (circular saw for steel, water jet for calcium sulfate); apply anti‑rust paint or PVC edge‑banding to cut edges; maintain panel gaps ≤1mm.
4. Integrate MEP Systems: Route power and data cables within the underfloor void.

Critical Installation Notes:
- Perform anti‑static grounding testing before installation – ensure system resistance is between 0.5 and 20,000 megohms.
- If the void is used as an HVAC plenum, use non‑combustible barriers to divide the space into zones not exceeding 10,000 sq ft.
- Always follow safety protocols when cutting panels – wear appropriate personal protective equipment.

XIII. Maintenance and Care Guidelines (Extended)

The basic maintenance suggestions were covered in Section VII. Below is a more detailed care guide:

Daily Maintenance:
- Daily: Vacuum or use anti‑static mop to remove dust and debris; check for exposed holes or trip hazards.
- Weekly: Inspect panels for damage (edge lifting, surface blistering, etc.).

Periodic Maintenance:
- Monthly: Check panel stability and sealing.
- Annually: Have a professional technician perform a full inspection and deep cleaning; verify grounding system integrity; vacuum the underfloor area to remove dust from pedestals and stringers.

Cleaning Precautions:
- Avoid excessive water – moisture can seep into panel edges, causing swelling or damage.
- Use neutral pH cleaners (solvent‑free) for spot cleaning.
- Dry rotary polishing is recommended to maintain surface appearance.
- Wheeled equipment can cause indentations or scratches – use protective mats in rolling zones.

Common Issue Resolution:
