Yukings reflective noise barriers use heavy rigid panels (galvanized steel, aluminum alloy or pre-cast concrete) that reflect sound waves back toward the source via the mass law, ideal for highways, railways and industrial sites where maximum sound insulation at mid-high frequencies is required. CE, EN 1794 and ISO certified with a 25-year design service life.
Reflective noise barriers deflect sound energy back toward the source rather than absorbing it, making them particularly effective at mid-high frequencies where dense rigid surfaces naturally provide high transmission loss. Yukings reflective panels are fabricated from solid galvanized steel, aluminum alloy or pre-cast concrete and mount on standard hot-dip galvanized H-beam posts with a non-perforated, maintenance-free face.

Heavy-duty reflective panel construction using the mass law principle, with quality and structural testing to EN 1793-3 and EN 1794 standards.
Solid rigid panels follow the mass law: every doubling of surface weight adds approximately 6 dB of transmission loss for better insulation.
Solid galvanized steel face, EN AW-5754 aluminum alloy or 50-120 mm pre-cast concrete panels depending on the project requirements.
Panel depths tuned to the required insertion loss target, with stiffer heavier sections providing higher transmission loss values.
Solid non-perforated face panel - no exposed absorptive infill material - delivering a clean low-maintenance reflective surface.
Structural design life of 25 years with a 15-year structural warranty on Yukings-manufactured posts, panels and fasteners.
Full structural testing to EN 1794 with wind load rating of 1.2 kN/m2 - suitable for most global highway infrastructure conditions.
CE marked factory with ISO 9001 quality management and full EN 1793-3 sound performance dossier for every barrier type.
20 ft / 40 ft HC / 40 ft OOG containerized shipping with full shipping documents delivered with every global project shipment.

Explore Highway Barriers →Reflective barriers use heavy rigid panels that reflect sound energy back toward the source following the mass law principle - they are most effective at mid-high frequencies. Absorptive barriers use porous mineral-wool infill behind perforated or louvered faces to convert sound energy into heat, providing broadband absorption. Yukings offers both types and hybrid combinations.
A properly designed Yukings reflective barrier provides 30 to 42 dB of insertion loss (DL) measured to EN 1793-3 depending on panel depth and construction. The actual on-site noise reduction depends on barrier height, proximity to receivers and ground reflection - our engineering team provides full project-specific acoustic calculations.
Yes. Reflective panels can be interspersed with 8/10/12 mm UV-stabilized polycarbonate or acrylic transparent window sections for driver visibility, especially on curved highway sections and bridge parapet installations. All window modules are fully CE tested to the same acoustic standards as the main panels.
Yukings reflective noise barriers are designed for a 25-year service life with a 15-year structural warranty on all manufacturer-supplied structural elements. Corrosion protection is provided by hot-dip galvanizing to ISO 12944 C3-M or C4-H depending on exposure, with optional RAL powder coating for aesthetic projects.
