raised flooring companies

In modern architectural design and intelligent space planning, raised access flooring has gradually become a standard facility in commercial buildings and data centers. As one of the first manufacturers of calcium sulphate flooring in China to obtain ISO 9001, ISO 14001, and OHSAS 18001 certifications, ZIli Floor has established a 15,000 m² smart factory in Changzhou since 1994, with an annual production capacity of 800,000 m² of high-performance flooring systems. ZIli is dedicated to providing high-quality calcium sulphate flooring solutions.

1. What is Calcium Sulphate Flooring?

Calcium sulphate flooring is a flooring material made primarily from calcium sulphate. It typically consists of a mixture of calcium sulphate cement, quartz sand, cellulose fibers, and other materials, processed through pressing, cutting, and surface treatment. This flooring is characterized by high strength, fire resistance, moisture resistance, and environmental friendliness, making it widely used in office buildings, data centers, clean rooms, and other settings.

2. Scientific Basis of Calcium Sulphate Flooring

Calcium sulphate (CaSO₄), as an inorganic compound, has crystal structure characteristics that make it an ideal core material for flooring. ZIli uses γ-anhydrite (CaSO₄·0.5H₂O) as the core raw material, implementing three technological innovations:

Hydration Control Technology: Precisely controls the 140℃ calcination process, achieving a water absorption rate of ≤0.3% (industry standard ≤1.2%).

Molecular Reconstruction Technology: Adds nano-silicates to form a zeolite-like structure, resulting in a compressive strength of 45 MPa (compared to 28 MPa for ordinary gypsum boards).

Fireproof Lattice Technology: Releases crystalline water (H₂O) when exposed to fire, slowing the temperature rise rate to 0.8℃/min (EN 1363-1 certified).

3. Five Core Advantages of Calcium Sulphate Flooring

1. Dynamic Load Capacity

Through finite element analysis (FEA), the structure is optimized, allowing single panels to bear loads of up to 1200 kg/m². A case study in a data center in Shanghai showed that ZIli flooring exhibited no structural cracks over a 10-year usage period.

2. Exceptional Fire Performance

In a 1000℃ flame test, the flooring maintained integrity for 120 minutes (GB 8624 A1 level). This is due to the heat-absorbing dehydration reaction of calcium sulphate:

This process absorbs 3.78 MJ/m³ of heat, significantly delaying the spread of fire.

3. Environmental Adaptability

Weather Resistance: Dimensional changes ≤0.15 mm/m in environments ranging from -30℃ to 80℃.

Moisture Resistance: In RH95% environments, weight gain after 48 hours is <0.5%.

Chemical Resistance: Passed ASTM G85 salt spray testing for 1000 hours.

4. Acoustic Optimization Design

Utilizing a sandwich structure (calcium sulphate core + polyurethane damping layer), impact sound pressure levels are reduced to ≤58 dB (ISO 10140 standard). Measurements in a concert hall in Tokyo showed a low-frequency noise reduction of 45 dB at 125 Hz.

5. Sustainable Manufacturing

During production, 32% of the raw materials are recycled gypsum powder, and the flooring is 100% recyclable. It has received dual certifications for LEED v4.1 and BREEAM, with carbon emissions reduced by 62% compared to traditional concrete panels.
