Through the comprehensive control of long and short cycle costs, the overall cost-effectiveness of the project is maximized under the premise of quality standards.

Common Mistakes to Avoid When Choosing Airport Ceiling Systems

Emphasis on Appearance Design, Light on Practical Performance

Many projects focus on pursuing the aesthetic effect of ceiling shapes and ignore the core requirements of fire protection, noise reduction and operation and maintenance in airports. High-value ceiling with insufficient performance will lead to noisy space, high energy consumption and frequent renovation in the later stage, resulting in a waste of resources.
Selection needs to adhere to the performance priority, face value as a supplement, choose linear, perforated and other balance between aesthetic and practical aluminum ceiling, to achieve a balance between design and function.

Neglecting International Aviation Safety Codes

Part of the project only meets the fire safety standards of ordinary buildings, and does not adapt to the exclusive aviation codes such as ICAO and NFPA, which involves the risks of failure of acceptance, safety hazards, and insurance failures.
It is necessary to strictly lock the A1/A2 non-combustible aluminum ceiling and verify the aviation inspection report of the product to ensure that it fully meets the highest airport safety standards.

Neglecting Space Acoustic Noise Reduction Needs

Choosing ordinary ceiling without sound-absorbing structure in noisy areas such as waiting halls and lobbies will lead to serious space reverberation and fuzzy broadcasting, which will lead to complaints from passengers and degradation of traveling experience.
Core passenger areas must use perforated aluminum panels with sound-absorbing backing and drop sheet ceilings to ensure acoustic comfort in the space.

Focusing Only on Initial Procurement Costs

Blindly selecting low-priced, low-quality ceiling products reduces the initial budget, but the material is easy to corrode, breakage, short service life, later operation and maintenance, renovation costs are extremely high, and the overall cost-effectiveness is extremely low.
Need to account for the full life cycle cost, give priority to high-quality aviation-grade aluminum ceiling, in order to reduce the long-term stability of long-term operational losses.

Neglecting Green Selection Criteria

Neglecting the recycled content, VOC emission, recyclability and other environmental indicators of ceiling products will result in airports not being able to achieve green building certification, which is not in line with the low-carbon development trend of the industry.
The full selection of highly regenerative and recyclable aerospace aluminum ceiling helps airports to complete green rating and low carbon indicators.

Blindly Choosing Low-priced and Unqualified Suppliers

Choosing suppliers based on low price and neglecting product qualification and aviation project construction experience will easily lead to problems such as substandard product quality, delayed construction period and no after-sale protection, which will affect the landing of the project.
Priority should be given to professional manufacturers who are deeply engaged in the aviation field, checking product testing reports, BIM supporting services and project cases to ensure quality.

Underestimate the Loss of Special Environment in the Airport

Choosing ordinary aluminum finishes can't adapt to the high humidity, frequent chemical disinfection, temperature fluctuations in the airport environment, and long-term use is prone to discoloration, corrosion, paint loss and other problems, which affects the aesthetics and safety.
It is necessary to use aviation-grade aluminum alloy with high-quality anodic oxidation and powder coating technology to match the complex environment of airports.
