Unlike gypsum ceilings that absorb moisture and crack, it resists humidity (90% RH) and fire (fire rating Class A, ASTM E84), with service life up to 15-20 years. Customizable in size (max 1220×2440mm) and pattern (perforated, solid, linear), it is widely used in offices, hospitals, and transportation hubs.
Acoustic Performance: Perforated variants with mineral wool backing achieve NRC (Noise Reduction Coefficient) ≥ 0.65, reducing reverberation time by 50% in large spaces. A 200m² office with 0.8 NRC plates reduced noise levels from 75dB to 50dB.
Fire & Humidity Resistance: Class A fire rating (flame spread index ≤25, smoke developed index ≤450 per ASTM E84), withstanding 800°C for 30 minutes. Resists 90% RH humidity with no warping (tested for 1000 hours), suitable for swimming pools and bathrooms.
Lightweight & High Strength: Aluminum alloy plates (thickness 0.5-1.5mm) weigh 1.5-3kg/m² yet withstand 500Pa static load without deformation. Galvanized steel plates (thickness 0.8-2.0mm) handle 1000Pa load, ideal for industrial ceilings.
Easy Maintenance & Replacement: Smooth powder-coated surface (Ra < 1.0μm) resists dust accumulation—cleaning with a damp cloth restores brightness in 2 minutes. Modular design allows single-panel replacement (10 minutes/panel) vs. full ceiling replacement for gypsum.
Office Buildings: Acoustic ceilings for open-plan offices. A New York open office used perforated aluminum plates (NRC 0.75), reducing noise by 25dB and increasing employee productivity by 15% (survey data). The white finish enhanced natural light reflection (70% reflectivity).
Hospitals & Healthcare Facilities: Hygienic ceilings for operating rooms. A German hospital adopted 316L stainless steel plates, complying with ISO 14644-1 Class 5 cleanliness and resisting disinfectant corrosion—cleaning time reduced by 30% vs. gypsum ceilings.
Transportation Hubs: Durable ceilings for airports and subway stations. A Tokyo subway station used galvanized steel plates, withstanding 1000Pa crowd load and humidity (85% RH) without damage—maintenance costs cut by 60% vs. traditional ceilings.
Q: Which material fits humid environments (e.g., swimming pools)?
A: 304 stainless steel (corrosion rate <0.01mm/year) or marine-grade aluminum alloy (anodized finish). Both resist 90% RH humidity and chlorine corrosion. Avoid galvanized steel (rusts in 6-12 months in chlorinated environments).
Q: How to improve acoustic performance?
A: Choose perforated plates with ≥20% open area and pair with 50mm mineral wool backing—this increases NRC by 0.3 vs. solid plates. For recording studios, use micro-perforated plates (hole size 0.5mm) with NRC ≥0.9.
Q: What’s the maximum panel size for ceilings?
A: Standard max size is 1220mm × 2440mm (aluminum); galvanized steel maxes at 1220×1220mm (to avoid warping). Larger sizes (up to 2000×3000mm) require additional supports (every 500mm) to prevent sagging.
Q: Can ceiling metal plates be painted on-site?
A: No, on-site painting leads to uneven finishes and poor adhesion. Choose factory-applied powder coating (200+ colors) with 30μm thickness—this ensures 10-year color retention. Touch-up with matching spray paint for small scratches.
