Company Introduction

Who We Are: A Source Factory for Acoustic Protection in China

Engineering-led manufacturing for contractors, consultants and distributors who need barriers that are measured, documented and delivered on schedule.

HANWEI Noise Barriers — legally Anping Hanwei Wire Mesh Manufacturing Co., Ltd. — is a Chinese manufacturer of sound barriers and acoustic control systems located in Anping County, Hengshui, Hebei Province, the country's wire-mesh and metal-fabrication centre. Since 2013 our business has been deliberately narrow: designing and producing noise control products that are verified by measurement rather than by brochure.

The product 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, available 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 full test documentation. Our acoustic laboratory verifies 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 on highways, railways and factory boundaries in China, and our export team supplies contractors and distributors across 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 2–3 working days.

Application Profiles

Typical Projects and How They Are Solved

Representative configurations we deliver regularly. Final numbers are project-specific and confirmed in the technical proposal.

Highway corridor

Absorptive noise wall along an expressway

Challenge: Residences 18 m from the carriageway exceeded the local daytime limit, and the client required a compliant absorptive wall with a 20-year service life.
Solution: 3 m absorptive post-and-panel barrier on Q235B posts sized to the local wind pressure, 85 μm hot-dip galvanizing, panels with 80 mm mineral wool core and perforated facing.
Outcome: Insertion loss in the 10–15 dB(A) band, delivered as modular panels for fast site assembly, with material and acoustic test reports for the authority.

Rail / metro

Metro depot boundary and equipment screening

Challenge: Depot ventilation and trackside equipment noise was audible in adjacent housing, with tight clearances and limited foundation depth.
Solution: Combination of shorter absorptive barriers, transparent PC sections where sight lines mattered, and a dedicated enclosure for the ventilation plant.
Outcome: Source and path treated together, so the boundary could stay low without losing the architectural intent.

Industrial plant

Cooling-tower and compressor noise control

Challenge: A plant needed to meet the boundary limit at night while its cooling-tower fans and compressors had to run at full load.
Solution: Matrix-type silencers on the tower discharge, an acoustic enclosure around the compressor set, and acoustic louvres on the building intakes — all sized together against the pressure-loss budget of the running fans.
Outcome: Noise reduced at source, which kept the barrier height and therefore the project cost down.

FAQ

Questions Overseas Buyers Ask Us Most

If your question is not here, send it to our engineers — we answer technical questions in writing.

How much noise reduction can I expect from your barriers?

It depends on height, length and build-up: typical insertion loss is 10–25 dB(A), with absorptive panels reaching NRC ≥ 0.85. We run an acoustic simulation for your site — barrier height, length, ground conditions and the receiver position — and confirm the expected reduction in the technical proposal before you commit.

Can you produce to my country's wind and seismic standards?

Yes. Our structural engineers design posts, base flanges and foundations to the code that applies on your site — we work to the national standard of the project country, and to your own specification where you supply one. Send the design code, wind pressure and seismic parameters with your inquiry and we confirm compliance in the proposal, with the calculation available on request.

What is the minimum order quantity?

There is no hard minimum for standard configurations — trial orders from 100 ㎡ are accepted, though unit pricing improves above 1,000 ㎡ because tooling and container space are shared. For fully engineered systems with custom drawing work, the practical minimum is one container load.

How long does production take?

Standard sections held in stock ship in about 7 days; typical project orders run 15–30 days from approved drawings, and custom-engineered items with acoustic simulation and shop drawings add 2–3 working days at the proposal stage. Larger programmes are delivered in stages so site work can start before the whole order is finished.

What testing and documentation do you provide?

Absorption coefficient, insertion loss and sound power are measured in our own laboratory, and each batch ships with its test report, material certificates, galvanizing thickness report, coating thickness record, dimensional inspection record and packing list. Documentation is issued in English.

How are the products packed and shipped?

Panels and posts are bundled on steel pallets with corner protection, tagged and strapped, and shipped in 20GP, 40HQ or 40OT containers with a loading plan so nothing is damaged in transit. We handle EXW, FOB, CIF and DAP, and provide the full export document set.

Do you supply installation support overseas?

Every order ships with English installation manuals, component drawings and hardware lists, and we provide remote video supervision while your own crew erects the barrier. We are a product manufacturer: the goods we supply are the barriers, panels, silencers and louvres themselves, and installation is carried out by your contractor or your own site team. Send us the drawing before you order and we will detail the post layout, fixings and panel sequence so your installer works from a complete package.

Do you accept factory audits and third-party inspection?

Yes. We welcome factory audits and third-party inspection (SGS, BV, TÜV and similar) at any stage, and can arrange pre-shipment inspection with the inspector of your choice. Audit access is a normal part of our export quality process, not an exception.

How do I get a quotation?

Send the project type, location, required quantity, and any drawings or noise data you have. Standard configurations are quoted within 24 hours; engineered proposals with acoustic simulation and CAD drawings take 2–3 working days. Phone and WhatsApp: +86 18831881133, answered by our export desk at any hour, 7 days a week.
