Target reduction (e.g. Rw≥25dB), panel material (galvanised steel / aluminium), infill thickness, size and whether an acoustic door / access is included decide the unit price.
Galvanised-steel composite ~800–1400 CNY/m²; aluminium composite slightly higher ~1000–1600 CNY/m² (lighter, better weather resistance). Higher reduction needs more layers and mass, raising price.
Acoustic doors (≥30dB) and access openings are standard, usually priced per door (~4500 CNY/door reference); A-class non-combustible and fluorocarbon outdoor finish add a little but last longer.
Set a realistic reduction target; ask for a turnkey quote covering framing, install and acceptance; require fire/non-combustible certs.
Send equipment size, noise spectrum and site; ASPER issues a three-sheet quote within 24h covering panel, door, accessories and install.
Common Rw≥25dB; set by measured noise, don't over-build.
Galvanised for budget; aluminium for light/weather, slightly higher.
Door usually per-door; it is the standard enclosure access.
Odd shapes, extra height, demountable panels raise labour.
