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.

Aluminum Perforated Plates for Highway Noise Barrier

Typical Specification for Noise Barrier with Perforated Alu Materials:

1.Material Type: Aluminum –perforated, with fiber weathered proof
2.Durability: 20 years
3.Acoustic properties: minimum noise reduction coefficient of 0.35-0.6
4.Sound Reduction: 30-35 db.
5.Thickness: 10 cm , Height : 12 ft
6.Barrier Mounting Requirements: Structure mounted barrier.
7.Drainage Requirements: Weep holes should be provided in panels, where necessary, to facilitate proper drainage. Drainage design should not create noise leaks.

Installation of Zn/Al noise barriers usually resulted with 30-35 sound reduction. Warranty period should be at least 10 years.

Architectural Perforated Aluminum Acoustic Panels
When used as acoustical panels for architectures or buildings, the perforated aluminum sheets are made to custom sizes square tiles punching into round or slotted uniform patterns. The punched metal sheets are used as interior ceiling panels and wall panels for decoration and sound insulation. Very popular high grade building materials for modern halls and buildings.
