Middle density fiber cement building boards are high-performance construction materials made from Portland cement, quartz sand, and wood fibers. These boards provide the perfect balance of strength and workability for various building applications.
Middle density fiber cement building boards are high-performance construction materials made from Portland cement, quartz sand, and wood fibers. These boards provide the perfect balance of strength and workability for various building applications.
Middle density fiber cement building boards offer exceptional advantages:
Optimal Density – 1.2-1.5g/cm³ for perfect strength-to-weight ratio
A1 Fireproof Rating – 240-minute fire resistance (GB8624-1997)
Moisture Resistant – ≤30% water content prevents warping
High Strength – ≥16MPa bending strength (GB/T7019-1997)
Frost Resistant – Withstands 25 freeze-thaw cycles
Sound Absorbing – 45dB noise reduction (GBJ75-84)
Our middle density fiber cement boards meet strict quality standards:
Available Sizes: 1200×2400mm to 1220×3000mm
Thickness Options: 5-30mm (custom sizes available)
Surface Finishes: Sanded smooth for easy finishing
Edge Types: Square or tapered edges available
Certifications: ISO 9001, multiple GB standards
Compared to traditional materials:
| Feature | Our Boards | Gypsum Board | Plywood |
|---|---|---|---|
| Fire Rating | 240 min | 60 min | Combustible |
| Moisture Resistance | Excellent | Poor | Moderate |
| Lifespan | 30+ years | 5-7 years | 10-15 years |
Middle density building boards are ideal for:
Exterior Wall Cladding – Weather-resistant protection
Interior Partitions – Fire-rated and soundproof
Suspended Ceilings – Lightweight yet durable
Each board undergoes:
High-pressure forming (9000T press)
24-hour autoclave curing
Precision thickness calibration
Rigorous quality testing
