Explore Sinsun Hardware's industry-leading product lines, crafted to precise metallurgical standards with global delivery excellence.
Sinsun Hardware, established in 2006, is a leading manufacturer and global supplier of high-quality fasteners and engineered metal systems. As Northern China's largest producer of high-grade Self-Tapping Screws and heavy-duty structural components, we operate from a gigantic 30,000 sqm integrated facility. This includes modern production zones, a 12,000 sqm smart warehouse with an 18,000+ pallet capacity, and multi-language customer support centers. Our annual output exceeds 8,500 containers, continuously servicing key global markets in the Middle East, Southeast Asia, South America, and Russia.
Expanding on our foundation of cold-forging, drawing, and precision stamping, Sinsun Hardware acts as a premier ODM and OEM manufacturer of Expanded Wire Mesh. Utilizing high-grade steel sourced directly from industry giant Xingtai Steel, we conduct in-house spheroidizing annealing, precision drawing, and custom stamping. This ensures optimal microstructure, flatness, and tensile strength (exceeding 1,000 MPa) for all expanded metal products.
Our journey of technical expansion, scale scaling, and digital integration over the past two decades.
Established Sinsun in Northern China, focusing on high-speed wire processing and premium fastener production.
Acquired direct export certifications, expanding operations to serve clients in South America, Southeast Asia, and Eastern Europe.
Introduced German-engineered multi-station cold heading machines and advanced automated metal expanding equipment.
Achieved an annual output of over 36,000 tons. Integrated four state-of-the-art continuous heat treatment lines and computerized warehouse dispatch systems.
How our advanced manufacturing translates raw metal coils into high-tolerance, functional expanded mesh panels.
Unlike woven wire mesh, expanded metal is slit and stretched in one continuous process, creating uniform diamond openings. This eliminates waste and maintains the structural integrity of the parent steel sheet.
Equipped with computerized high-speed press machinery, Sinsun guarantees a tolerance level of ±0.02mm on strand thickness and width, meeting strict military and architectural requirements.
Our raw material feedstock relies on premium carbon steel (Ansteel C1022A), high-strength stainless steel (SS304, SS316), and lightweight marine-grade aluminum alloys, processed to resist extreme physical stress.

|---|---|---|---|---|
| LWD | Long Way of Diamond | 3.0 mm – 300 mm | ± 0.05 mm | Structural / Architectural Façades |
| SWD | Short Way of Diamond | 1.5 mm – 120 mm | ± 0.03 mm | Ventilation / Custom Filters |
| Strand Thickness | Gauge of raw sheet metal | 0.3 mm – 8.0 mm | ± 0.02 mm | Heavy Machinery Walkways |
| Strand Width | Feed size of slit action | 0.5 mm – 10.0 mm | ± 0.02 mm | Perimeter Security Fencing |
| Open Area % | Permeability index | 15% – 85% Custom | ± 1.0% | HVAC / Soundproofing Systems |
From chemical filtration barriers to windproof highway shielding, our expanded wire mesh adapts to heavy industrial environments.
Modern commercial architecture utilizes aluminum expanded mesh for rainscreen facades and sunshades. Sinsun provides custom PVDF and anodized coatings, offering over 1,000 hours of salt spray and UV degradation resistance. This achieves a perfect balance between passive shading, natural ventilation, and aesthetics.
Designed to sustain high mechanical stress, our multi-layered stainless steel micro-mesh works as support baskets and core filtration media in refinery centrifuges, seawater desalination plants, and chemical processing facilities, showing superior corrosion resistance under high temperatures.
For railway grids, prison fences, and industrial walkways, Sinsun manufactures raised and flattened carbon steel mesh. Annealed in-house to achieve high hardness (HRC 28-32) and high tensile strength (1,000+ MPa), our mesh is highly resistant to cutting tools and heavy impact.
Precision hardened fasteners with drill points.
High strength threads for steel and wood connections.
Masonry anchoring screws with high torque capacity.
Hardened steel nails for heavy-duty structural anchoring.
Sinsun Hardware operates Northern China’s most reliable metal-working production lines. By controlling the supply chain from raw metal selection to wire drawing, annealing, slitting, expanding, and surface treatment, we eliminate dependencies that slow down standard manufacturers.
Our production prowess is driven by German-imported machinery, precision Taiwanese technology, and a dependable staff of trained specialists. We offer over 20,000 SKUs of nails, screws, wires, and rivets, alongside custom-engineered expanded metal products. Each batch undergoes 12+ stringent quality checks to assure outstanding polish (Ra ≤ 0.4μm), corrosion resistance (1,000+ hours salt spray test), dimensional accuracy (±0.02mm), high strength (1,000+ MPa), and consistent hardness (HRC 28-32).
With our integrated ERP warehouse system and 12,000 sqm physical storage capacity, we optimize dynamic inventory levels to guarantee stable lead times. Whether your project demands standard rolls or custom ODM panel sizes, we ensure consistent delivery schedules, with a global shipping capacity of over 8,500 containers annually.

Technical answers directly from Sinsun Hardware's metallurgical and design departments.
Raised Expanded Metal: As it comes off the machine, the strands are set at an angle to the plane of the sheet, providing an anti-slip texture that is ideal for walkways and security screens.
Flattened Expanded Metal: The raised mesh is passed through a cold-rolling flattening machine, aligning the strands into a single plane. This reduces thickness by up to 5% and creates a smooth surface suitable for structural shelves, architectural guards, and filtration panels.
During the expanding process, mechanical stresses accumulate within the metal sheet. Sinsun utilizes continuous, multi-roll leveling machines that apply precise pressure to neutralize internal stresses. This process ensures that panels remain flat within a deviation tolerance of ≤ 2mm per meter, avoiding bowing during installation.
Yes. Our ODM capabilities allow us to design custom molds for non-standard opening geometries, including hexagonal, square, round, and micro-mesh patterns down to 1.5mm SWD. These are ideal for high-precision petrochemical and HVAC filtration systems.
Lead time depends on part complexity, quantity, and finishing requirements. For standard items, it can be 4-6 weeks. By utilizing our integrated ERP-driven smart warehousing system and keeping an inventory of pre-drawn raw wire, we regularly achieve an on-time delivery rate exceeding 99%.
With every shipment, Sinsun provides comprehensive certification, including ISO 9001 quality compliance certificates, raw material chemical composition reports (MTRs), hardness verification reports (HRC), tensile strength logs, and coating thickness measurements (anodized or galvanized microns).
