  • Q: Will the sound absorption effect of the soundproof and fireproof panels decrease after 3 years of use?
    A: 
    A gradient pore size sound absorption structure is used. It is AGBB certified, and the sound absorption coefficient decreases by ≤5% over a 10-year service life. Annual acoustic testing and cleaning maintenance services are provided to ensure continuous noise reduction.
  • Q: How are the steel structure materials for the terminal building protected against corrosion in the high salt spray environment of a cross-sea airport?
    A: 
    A three-layer composite galvanizing + weathering steel process is used. It withstands 5000 hours of salt spray testing without red rust. On-site welding process guidance and a 20-year corrosion protection warranty are provided to ensure structural safety.
  • Q: How are the special building materials for aviation signage maintained in smoggy weather?
    A: 
    The fluorescent ceramic particles use double-layer reflective technology. The visibility distance remains ≥600 meters even in smoggy weather. Quarterly cleaning and maintenance services and reflective performance testing are provided to ensure that navigation signs are clearly identifiable around the clock.
