A Source Factory for Acoustic Products, Not a Reseller
Sound Barriers, Built to Block Noise.
Anping Hanwei Wire Mesh Manufacturing Co., Ltd. has manufactured acoustic products since 2013 from a 10,000+ ㎡ plant in Anping County, Hebei — the centre of China's wire-mesh and metal fabrication industry. We build highway and railway barriers, absorptive panels, transparent PC panels, ventilation silencers and acoustic louvres, and we ship them to contractors and distributors worldwide with full test documentation.
Overseas business is product supply. We manufacture the acoustic products and provide English shop drawings, component drawings and batch test reports; installation is carried out by the buyer's own contractor. We do not send installation crews or run turnkey noise control works abroad.

Engineering-Led Manufacturing, Verified by Measurement
We deliberately kept the business narrow: noise control products that are proven by test data rather than by brochure claims.
Our scope covers the full noise-control chain. Barrier systems — galvanized post-and-panel highway and urban road barriers, high-speed rail and metro sound walls, transparent PC panel combinations, community barriers for residential and school zones, and mobile temporary barriers for construction and maintenance works. Acoustic materials — perforated metal acoustic panels and custom absorptive panels with NRC ≥ 0.85, supplied with mineral wool, polyester or PET cores to your specification. Source-level equipment — industrial acoustic enclosures for fans, compressors and pumps, HVAC and cooling-tower silencers, acoustic louvres, anechoic test chambers, soundproof doors and sound-absorbing wedges. Accessories — H-section steel posts, base flanges and anchor sets, produced in the same plant so posts and panels always match.
Everything is made in-house: coil slitting, CNC punching and roll forming, hot-dip galvanizing, powder coating, panel assembly and mounting hardware. That vertical integration is why we can quote factory prices on project quantities while still shipping a complete test and material documentation set. Our acoustic laboratory measures absorption coefficient, insertion loss and sound power, and our structural team checks posts, foundations and connections against the wind and seismic codes that apply on your site.
Domestic experience is what we export. Barriers from this plant protect communities along highways, railways and factory boundaries across China, and our export team supplies contractors and distributors in Southeast Asia, the Middle East and Africa with English drawings, material certificates, test reports, sea-worthy packing and container loading plans. Standard configurations are quoted within 24 hours; engineered projects with acoustic simulation and shop drawings typically take 2 to 3 working days.

What We Do In-House, and How It Is Verified
Every claim below is backed by equipment you can see or documentation you can audit during the order process. Production follows the Chinese GB series; export projects are built to the standard you nominate, and we document to that code rather than to a certificate we do not hold.
| Capability | In-house equipment or process | How it is verified |
|---|---|---|
| Coil slitting & roll forming | Slitting line, CNC roll forming, H-section and C-post tooling | Section dimension and thickness check per batch |
| CNC perforated panel punching | Turret punch and CNC perforating lines; round, slot and square hole patterns | Hole pattern and open-area sample on the first panel |
| Hot-dip galvanizing | 85 μm zinc coating as our default, heavier coating to your specification | Zinc thickness reading and bath analysis report per batch |
| Powder coating | Electrostatic line, 60–80 μm cured film as standard, film thickness and RAL colour to your specification | Film thickness reading and colour check against the approved sample |
| Acoustic laboratory | Absorption coefficient, insertion loss and sound power measurement | Laboratory report issued for the batch you receive |
| Absorptive panel assembly | 80 mm centrifugal glass wool core, 48 kg/m³ density, perforated facing | NRC ≥ 0.85, confirmed by laboratory test |
| Structural engineering | Post and foundation calculation for local wind pressure and seismic zone | Calculation note issued for approval before production |
| Barrier acceptance design | Insertion loss calculated on your actual height, spacing and post spacing | Acoustic simulation report in the technical proposal |
| Export packing & loading | Sea-worthy packing, container loading plan, export documentation | Packing list and loading photos before container sealing |
In-house production
Slitting, punching, roll forming, galvanizing, powder coating and panel assembly under one roof. Full material traceability from coil to finished panel, and no trading-company markup in the price.
Acoustic testing
Every absorptive panel batch is laboratory-tested. NRC, insertion loss and sound power reports ship with your delivery; third-party verification is available on request.
Engineering team
Structural and acoustic engineers size posts to your wind load and seismic code, and issue CAD drawings for approval before any steel is cut.
Export logistics
Sea-worthy packing, container loading plans, and the full export document set handled in-house, so customs and site clearance do not stall your schedule.
Quality control
Galvanizing thickness, coating film, panel dimensions and hole patterns are checked and recorded for every production batch, and the readings ship with the delivery. Third-party inspection is welcome at any stage.
Installation support
English manuals, component drawings and hardware lists, plus remote video supervision for your installation team.
How the Business Developed
From a local wire-mesh workshop to an export-capable acoustic manufacturer.
Founded in Anping
Started manufacturing wire-mesh acoustic products for industrial clients in Hebei, with coil slitting and basic panel assembly.
Entered highway projects
Started supplying expressway noise barriers; cumulative barrier length passed 100 km across provincial projects.
Railway and metro
Barrier systems deployed on high-speed rail and metro lines; capacity expanded and galvanizing line brought fully in-house.
Dedicated export team
Established a dedicated export department; first overseas projects delivered to Southeast Asia and the Middle East.
Acoustic laboratory
In-house laboratory commissioned for absorption, insertion loss and sound power measurement, so acoustic data no longer depends on outside test houses.
Full acoustic product range
Enclosures, ventilation silencers, acoustic louvres, anechoic chambers and soundproof doors added, covering the complete noise-control chain.
Questions Buyers Ask Before the First Order
Straight answers on MOQ, documentation, lead time and installation support.
Are you a manufacturer or a trading company?
We are the manufacturer. Anping Hanwei Wire Mesh Manufacturing Co., Ltd. owns the plant in Anping County, Hebei — coil slitting, CNC punching, roll forming, hot-dip galvanizing, powder coating and panel assembly all happen in-house. You deal with the factory that builds your order, not an intermediary who resells it.
What is your minimum order quantity?
There is no fixed MOQ for standard configurations — we quote per project. As a practical reference, a full container load typically starts around 100 linear metres of barrier, and mixed containers with different sections are acceptable for trial orders.
Do you provide acoustic performance data with the delivery?
Yes. Absorptive panels ship with NRC test reports from our in-house laboratory, and barrier systems are supplied with material certificates and insertion-loss data calculated on your actual height, length and post spacing. Third-party verification is available on request.
Which standards do your products follow?
We build to the standard that applies on your project. Domestic work follows the Chinese GB series; export projects are designed and produced to the standard or specification you nominate, or to the standard used in the project country. Tell us the code in your tender document and we will design, produce and document to it — nothing is held to a standard we have not actually tested against.
How long does production take?
Standard configurations on stocked tooling ship in 7 to 15 days. Engineered projects that need acoustic simulation, shop drawings and structural calculation typically take 2 to 3 working days for the proposal, with production scheduled after drawing approval.
Do you support installation outside China?
Yes, as a product supplier. Every order ships with English installation manuals, component drawings and hardware lists, and our engineers can join by video call to walk your installer through the post layout and panel sequence. Installation itself is carried out by your own contractor — we manufacture and supply the barrier, panel and acoustic equipment, we do not send crews abroad.
