Advantages

Fireproof & Non-Combustible: Calcium sulfate panels are fire-resistant, heat-insulating, and non-combustible, effectively slowing fire spread without releasing harmful gases.

High Mechanical Strength: Manufactured from high-strength gypsum powder, the panels offer excellent structural performance and meet international standards, including CE certification.

• Sound Insulation: The calcium sulfate and fiber composite structure reduces vibration and impact noise, and thus play a sound insulation effect.

Excellent Load-Bearing Capacity: Edge load capacity is equal to center load capacity, preventing edge warping caused by uneven stress distribution.

Eco-Friendly Materials: The calcium sulfate core is made from sustainable raw materials, is 100% recyclable, and achieves a recovery rate of up to 85%, with water-soluble adhesives.

Water Resistant: The integrated panel structure provides reliable moisture resistance, preventing deformation, wrinkling, or delamination even under prolonged exposure to humidity.

Frequently Asked Questions?

A raised access floor is a modular flooring system elevated above the structural slab using steel pedestals and stringers, creating an underfloor plenum.
It is widely used in data centers, offices, control rooms, and electrical rooms to support cable management, air circulation, heat dissipation, anti-static protection, and equipment vibration control, while allowing flexible layout changes and convenient maintenance.

Raised access flooring is mainly classified into two categories based on function and application:
•Anti-static raised access floor – designed for data centers, server rooms, and electronic equipment areas
•Network raised access floor – used in office spaces for structured cabling and weak-current systems
Each type can be combined with different surface finishes such as HPL, PVC, ceramic, or carpet.

The height of a raised floor depends on application requirements:
•Office areas: 100–300 mm
•Data centers / equipment rooms: 300–800 mm
•Special projects: Custom heights above 1000 mm available for high-density cabling or airflow requirements

To ensure effective ESD protection, anti-static raised floors must comply with the following:
•Surface resistance: 1 × 10⁶ – 1 × 10¹¹ Ω
•System resistance (panel–pedestal–ground): 1 × 10⁴ – 1 × 10⁹ Ω
These values meet international requirements for protecting sensitive electronic equipment.

For long-term performance and safety:
•Avoid impacts from sharp or heavy objects to prevent surface damage
•Use professional suction lifters when removing panels—never pry forcibly
•Regularly inspect the grounding system to ensure compliance
•Keep underfloor cables organized to avoid excessive load on pedestals
•Replace damaged anti-static finishes promptly to prevent ESD failure

Material & Durability
•HPL: High hardness, excellent wear, scratch, and impact resistance, long service life
•PVC: Softer material, lower wear resistance, more prone to scratches
Anti-static Stability
•HPL: Integrated anti-static layer formed during lamination, stable and long-lasting
•PVC: Surface-coated anti-static layer, performance may degrade over time
Environmental Resistance
•HPL: Resistant to moisture, heat, chemicals, and easy to clean
•PVC: Lower heat and chemical resistance, water exposure may cause edge lifting
Installation & Applications
•HPL: Ideal for data centers and power rooms with long-term fixed layouts
•PVC: Seamless installation option, suitable for areas requiring flexibility or slight subfloor tolerance

Common causes include:
•Improperly installed or uneven pedestals and stringers
•Incomplete contact between pedestal bases and subfloor
•Excessive gaps between floor panels causing friction
Solutions:
•Re-adjust pedestals for vertical alignment and firm fixing
•Add metal shims under pedestal bases
•Replace damaged components and control panel gaps within ≤ 0.5 mm
