Import 12mm Perforated Gypsum Board — Buy in wholesale FOB from Supplier in China

Zhangjiagang Wellyoung Material Co offers a 12mm perforated gypsum board designed on the Helmholtz resonance principle, where the perforations, board thickness and rear cavity form resonant chambers that absorb sound energy as air molecules pass through the holes. The board carries a sound absorption coefficient (aw) of 0.65 and an NRC of 0.70, with a perforation rate between 6.8% and 19.6% depending on the pattern selected. It is supplied in 1200 x 2400 mm sheets with square edges, and the perforation options include round, square, cross, rectangular, long-round, cellular, micro and irregular hole geometries coded as patterns H1 through H8.

The surface can be finished as plain paper, PVC lamination or latex paint, while the reverse side is backed with acoustic non-woven cloth in white or black. Board density is listed at 9.4 kg/m² and thermal conductivity (K-value) at 0.1 W/m·K, with a stated climate tolerance of 70% relative humidity. These figures place the product within standard ranges for acoustic gypsum panels used in commercial interiors, though buyers should verify humidity performance for projects in tropical or coastal climates where sustained moisture levels may exceed the stated threshold.

Typical applications include suspended ceilings and wall partitions in auditoriums, cinemas, offices, churches, hospitals and schools where controlled reverberation is needed. The supplier also lists compatible installation materials such as multipurpose interior putty, jointing compound, drywall screws, paper tape and glass-fibre mesh. Trade terms are not detailed on the listing, so MOQ, pricing, lead-time and shipping arrangements should be confirmed directly with Zhangjiagang Wellyoung Material Co before placing an order.

Zhangjiagang Wellyoung Material Co operates from A-15, Tixiang Plaza, Zhangjiagang, Jiangsu 215600, China. The company is listed under the platform's 'harbor' trust tier, which represents a basic verification level. The listing does not provide information on the company's establishment date, number of employees, production facilities or export destinations, so buyers should request these details as part of their supplier qualification process.

The platform shows a response rate of 0.00 and an average response time of 0 hours for this supplier, indicating no recorded enquiry history on the marketplace. This absence of data means buyers should send a direct test enquiry to assess the supplier's communication speed and the quality of technical information provided. Zhangjiagang's location in Jiangsu province places it within reasonable logistics reach of Shanghai and Ningbo ports, but specific shipping capabilities and export documentation should be verified before finalising terms.
