They offer a combination of strength, rigidity, and flatness, along with enhanced thermal and acoustic insulation properties. ACPs are widely used in curtain wall systems, facades, and interior partitions.
3. Perforated Aluminum Panels: These panels feature a pattern of holes or perforations, allowing for ventilation, light filtration, and acoustic control. They are commonly used in facades, screens, ceilings, and other architectural elements.
4. Honeycomb Aluminum Panels: These panels have a honeycomb core structure sandwiched between two aluminum sheets. The honeycomb core provides exceptional strength and rigidity while maintaining a lightweight profile. Honeycomb aluminum panels are used in aerospace, marine, and transportation applications where high strength-to-weight ratio is crucial.
5. Corrugated Aluminum Panels: These panels have a wavy or corrugated profile, providing additional strength and stiffness. They are often used in roofing, siding, and other applications requiring structural support and weather resistance.
6. Aluminum Tread Plates: These panels have a raised pattern or texture on their surface, providing slip resistance. They are commonly used in flooring, walkways, and other areas where safety is a concern.
