Perforated Metal Sound Absorbing Wall Panels

We supply aluminum, galvanized steel and SUS 304 punch plate panels used for construction sites, projects and highways to control noises and sound pollution. Unlike acoustic screens mainly for indoor decoration and sound absorbing, this noise barrier is mainly used for outdoor noise control and safety uses.

Two types according to panel forms: Shutter type checkered plate barrier and flat sheet perforated panel. They can be composed with filling materials.

Three types according to materials: Aluminum, Steel Galvanized or Hot Dipped, Corrosive Resistant Stainless Steel SUS304 or 316 Grade.

Temporary Sound Control Panels

We supply temporary noise barriers / attenuators for various commercial buildings, construction projects and installation projects. The metal panels can be used around the sites to suppress the construction noise and bring it down to acceptable levels.

Our perforated aluminum and steel panels are used for drilling trucks in air conditioning projects, based in urban or residential areas where noise coming from the drilling rig can be a major cause of sound pollution.

Perforated Metal Sound Insulation Noise Barrier for Public and Civil City Construction Projects

Perforated noise panels of metal sheets for European market have a standard height of 2000 mm, sheet thickness of 120 mm and the absorption can reach 28dB (B3).

Sound barrier metal walls have following popular sizes:
Length: 2000mm-4000mm
Width: 500mm-1000mm
Thickness:  70mm-100mm
Inner material: sponge or glass fiber

Features:
1) High light transmission: Up to 88% that of same thickness of general glass.
2) Excellent impact resistance: 80 times that of glass.
3) Weather and UV resistant: Temperature resistance range is -40º C ~ +120º C, with an ultraviolet coextruded film on the sheet surface. It can prevent the resin fatigue or yellowing caused by the ultraviolet.
4) Light weight: Only 1/12 of the weight of glass of the same thickness. It can be easily cold bent as well as thermal shaping.
5) Flame resistance: High fire performance rating is class B1.
6) Sound and heat insulation: Superb sound insulation and super thermal insulation.
7) Outstanding physical, mechanical, electrical and heat capabilities.

Uses: Building industry, construction projects and machinery industries, sky light system, safety panels.
