Aluminum Grid Ceiling Panels for Large Public Buildings
Aluminum grid ceiling panels are open ceiling systems made from AA3005 aluminum alloy, formed by roll forming and electrostatic spraying. Composed of interlocking horizontal and vertical bars forming square or diamond grids, they offer ventilation, sound absorption and decoration. With a three-dimensional grid appearance and free air flow, they are widely used in shopping malls, supermarkets, office buildings, stations and other public spaces.

Production Process
01
Roll Forming
Aluminum coils are uncoiled, leveled, and continuously roll-formed into grid bar sections with high straightness and dimensional accuracy.
02
Cutting
Precision cut to design lengths with clean, burr-free ends to fit grid sizes.
03
Pretreatment
Degreasing, descaling and chromate conversion to form a stable oxide film and enhance coating adhesion.
04
Coating
Polyester pre-coating for a uniform, stain-resistant, moisture-proof and colorfast finish.
05
Assembly & Inspection
Grid bars are interlocked, with splicing accuracy, flatness and stability checked before packaging.
Installation Structure (Refer to Diagram)
Keel System
Composed of main keel, sub keel and trim frame, with spring hangers for stable suspension.
Installation Method
Grid bars are interlocked in a clip-on system, forming continuous grids quickly, with individual units removable.
Visual Effect
Three-dimensional square grid visually extends space and creates an open, transparent feel, while concealing utilities above.
Application scenario
Shopping malls, supermarkets, specialty stores, corridors.
Office building lobby, public areas, and open-plan office areas.
Large public buildings such as train stations, airports, convention centers, and stadiums.
Underground parking garages, industrial plants, and warehouse spaces.

FAQ
1
Q: How is the ventilation effect?
A: The open grid structure allows free air flow, providing excellent ventilation and heat dissipation for large public spaces.
2
Q: Can it absorb sound?
A: The divided grid structure disperses sound sources to reduce echo resonance; adding acoustic backing improves performance.
3
Q: Is maintenance easy?
A: Individual grid bars can be removed directly for easy access to utilities and lighting fixtures.
