Noise Barrier & Sound Barrier

Applicable project types:

• Road/urban highway sound barriers
• Expressways & elevated roads
• Railway & metro/rail transit noise barriers
• Metro line section works

Typical solutions/forms: fully enclosed, semi-enclosed, vertical, U-trough, portal/steel-frame systems, transparent panels/roof components.

International standards (by application):

• Road noise barriers: EN1793, EN1794
• Railway noise barriers: EN16272, EN16727

Covered categories (structure types):

• Upright sound barriers
• Semi-enclosed sound barriers
• Fully enclosed sound barriers
• Folding-arm / portal-type enclosed structures

Product components (typical offerings):

• Metal sound-absorbing panel (concave-convex absorbing elements)
• Steel columns / steel frame structure
• Transparent boards/roof components (transparent PC / acrylic / laminated glass options)
• Composite pinhole sound-absorbing panels (e.g., filled with foam aluminum)

Strong and extensive sound barrier project achievements, covering highway and rail/urban rail/high speed railway noise barrier applications; includes upright, semi-enclosed, fully enclosed, U-trough, folding-arm/portal enclosed systems, and transparent/roof solutions.
