Product Overview
The Industry Standard for
High-Performance Spaces
Our Calcium Sulphate Core Panel is manufactured from 100% natural gypsum, encapsulated on all six sides with precision-formed galvanized steel sheets. The result is a panel of exceptional dimensional stability, superior fire resistance, and proven anti-static performance -- engineered to meet the most demanding requirements of modern raised floor installations.
Ideal for data centers, financial trading floors, office buildings, and cleanrooms where reliability, load capacity, and long-term performance are non-negotiable.

Why This Panel
Engineering Advantages
Every design decision is driven by real-world installation demands and long-term performance requirements.
100% Natural Gypsum Core
Sourced from premium natural gypsum deposits. No synthetic binders. The result is a dimensionally stable, non-combustible panel that will not warp, swell, or off-gas over its service life.
Six-Sided Steel Encapsulation
Precision-formed galvanized steel sheets on all six faces. Burr-free edges guaranteed. The closed construction prevents moisture ingress and delivers consistent load distribution across the entire panel surface.
Class A1 Fire Performance
Non-combustible classification under EN 13501-1. Gypsum's inherent fire resistance makes this panel the first choice for data centers, server rooms, and any space with stringent fire codes.
Anti-Static & ESD Control
With conductive or dissipative surface finishes, the system achieves surface resistance of 10⁶ - 10⁹ Ω. Critical for protecting sensitive electronic equipment in data centers and trading floors.
Precision Manufacturing Tolerance
Dimensional tolerance held to ± 0.2 mm. Consistent panel-to-panel flatness ensures seamless installation, minimal shimming, and a professional finish with tight grout lines.
Full Certification Package
CISCA, CE, and MOB test reports ready for project submission. Factory batch testing on every production run. Full documentation support for international project acceptance and customs clearance.
