Perforated Aluminum Acoustic Sheet for Highway Noise Barrier and Buildings

Aluminum perforated panels are popularly used as highway sound barriers and architectural acoustical panels. Aluminum alloy panels have light weight and excellent property of anti-corrosion and alkaline resistance. Suitable for both indoor and outdoor uses. Fitted with fibers and foams, the sound reduction function of the metal panels works even better. Perforated in slots, louve, round hole, other patterns.
