Main Damages of High-Humidity Environments to T-Grid
Long-term erosion by condensed water and moisture causes rust, corrosion, coating peeling and powdering.
Deformation and sagging of the grid lead to uneven ceiling, enlarged gaps and abnormal noises.
Rust diffusion after coating damage contaminates ceiling panels and shortens service life.
Coastal salt spray and chemical acid-base environments accelerate corrosion failure.
Core Moisture-Proof and Anti-Corrosion Technical Solutions
- Hot-dip galvanized steel strip
Adopts high-zinc-layer galvanized substrate with uniform and dense zinc coating, blocking contact between water vapor and oxygen.
- Aluminum alloy T-grid
Aluminum features natural corrosion resistance, ideal for bathrooms, kitchens, basements, coastal and other high-humidity & high-salt environments.
- Thickened / high-strength structure
Thickened T-grid is preferred in high-humidity environments to improve rigidity and reduce moisture-induced deformation.
- Double-sided electrostatic powder coating
Strong coating adhesion, water-resistant, alkali-resistant and mildew-proof, effectively isolating water vapor penetration.
- Passivation / chromate treatment
Enhances metal surface stability and improves corrosion resistance.
- Weather-resistant and antibacterial coating
Suitable for clean, humid and mildew-prone areas to inhibit mold growth.
- Fully enclosed section structure
Prevents water vapor from entering the grid interior and causing internal corrosion.
- Integrated anti-corrosion for accessories
Hangers, connectors and angles adopt the same grade anti-corrosion material to eliminate electrochemical corrosion.
- Sealing at splicing joints
Reduces water ingress, condensation and rusting at gaps.
- Ensure ventilation, air exhaust and dehumidification inside the ceiling to reduce condensed water formation.
- Provide insulation against condensation for pipelines and equipment.
- Properly reduce hanger spacing in humid areas to improve overall stability.
- Seal joints between corners and walls with mildew-proof sealant.
