Established in 2006, Sinsun Hardware has evolved from a targeted regional factory into a globally recognized benchmark for fastener, mesh, and wire design. Operating from Northern China, our state-of-the-art production hub represents the absolute zenith of precision metallurgy.
By integrating German-imported multi-station cold heading machinery with advanced Taiwanese design blueprints, our production capability yields unmatched dimensional accuracy (±0.02mm) and structural consistency.
All critical components and fencing elements are engineered to resist heavy environmental degradation. Our solutions withstand over 1,000 hours of continuous salt spray testing while retaining structural integrity (tensile strength ≥ 1,000 MPa).
Starting with high-grade carbon and alloyed steel sourced directly from XING TAI Steel, our facility handles in-house spheroidizing annealing, wire drawing, cold-forming, heat treatment, and surface coating processes.
Expanded metal mesh fencing is not simply "cut wire." It is formed by shearing and stretching a single solid sheet of steel or aluminum on a heavy-duty press. This precise mechanical process splits and stretches the raw plate into diamond-shaped openings while maintaining a continuous structure. Because there are no welds, joints, or woven points, the panel possesses inherent resistance to unraveling, cutting, and climbing. It represents a quantum leap in physical barrier security over traditional chain link or welded wire mesh configurations.
Unlike welded wire fence where welds can break under fatigue or stress, expanded metal panels form a unified monolithic piece. A cut made at any single strand will not result in unraveling, isolating local damage while maintaining complete perimeter containment.
The diamond geometry is designed with extremely tight Short Way of Design (SWD) openings, eliminating footholds for human trespassers. Furthermore, standard manual bolt cutters fail to gain adequate leverage on the 3D-angled strands.
The slanted angle of the strands facilitates excellent airflow, reducing aerodynamic drag on post support structures. It simultaneously provides optimal diagonal visual blocking for privacy, yet remains open when viewed straight-on for surveillance monitoring.

Sinsun Hardware controls the production process from raw wire rod and sheet coils to the final containerized shipment. We source our base raw structural steel from XING TAI Steel, a globally renowned steel mill with ultra-consistent metallurgical baselines.
Once inside our 30,000 square meter facility, the materials undergo specialized spheroidizing annealing inside computer-controlled, gas-fired furnaces. This critical thermal process reorganizes the carbon structure of the steel, optimizing it for cold stretching and preventing micro-fractures in the diamond intersections. The drawing processes are completed in-house on high-efficiency continuous drawing lines, guaranteeing that diameter and thickness measurements maintain a tolerance profile under ±0.02mm.
To secure extreme durability on high-carbon products and specialized self-tapping screws, we integrated four new high-capacity heat treatment lines in 2025. This modernization project ensures rapid turnaround, structural hardening consistency (HRC 28-32), and zero supply-chain delays for high-volume international procurement contracts.
Trace our mechanical and technological modernization roadmaps. We have systematically scaled up our hardware and mesh capabilities to service mission-critical infrastructure projects globally.
Architects, security directors, and civil engineering firms leverage expanded metal mesh systems due to their adaptive physical profile.
For high-security areas (prisons, borders, sensitive military hardware storage), we supply heavy-gauge steel panels coupled with anti-ram structures. These systems integrate seamlessly with perimeter detection cables, surveillance arrays, and razor tape top coils.
Electrical substations, chemical storage areas, and telecommunications towers require fencing that prevents access while providing venting properties. The diamond mesh layout facilitates constant airflow while keeping personnel safe.
Our highway expanded metal barriers prevent animal crossings, reduce high-beam glare from oncoming traffic, and secure pedestrian overhead bridges. They feature structural resilience under vibration stresses.
Modern commercial structures use expanded aluminum mesh for rain-screen facades and parking garage ventilation panels. It delivers unique shadows, shields interior spaces from direct solar gain, and offers structural longevity.
Different environments demand specific raw chemical matrices. At Sinsun Hardware, we configure fencing with three core metal profiles:
Our raw metal undergoes multi-tier chemical protection systems. We employ high-thickness hot-dip galvanization conformant to ASTM A123 / EN ISO 1461 parameters, yielding average zinc weights exceeding 505 g/m² for deep geological deployment.
For architectural styling and coastal protection, we apply electrostatic polyester powder coatings or PVDF (Fluoropolymer) coatings. The metal surface receives a multi-stage wash, an iron-phosphate pretreatment wash, and is oven-cured at 200°C to lock the cross-linked polymer matrix. This guarantees the mesh remains free of chalking, peeling, and under-film corrosion for over a decade.
Our manufacturing processes conform to internationally recognized benchmarks including ASTM F2548 (Standard Specification for Expanded Metal Fence Systems) and BS EN 10223. This alignment ensures seamless approval loops by local regulatory and engineering departments.
We supply engineers and procurement teams with 3D design files, structural wind calculation reports, and finite element analyses (FEA) to confirm wind and physical impact resistance before fabrication.
Due to the sharp, structural nature of expanded metal panels, transit damage can occur. We utilize custom heavy-duty wood framing and steel bands with protective corner guards to guarantee mesh remains flat, unbent, and ready for immediate job-site installation.
Raised expanded metal is the standard form direct from the shearing press, where the strands sit at an angle to the flat plane of the sheet, providing a 3D texture that makes climbing exceptionally difficult. Flattened expanded metal is run through a cold-reduction mill to flatten the strands, making the panel surface flat and thinner, though slightly decreasing overall structural rigidity.
Welded mesh relies on spot welds that can be cut with manual wire cutters or broken under repetitive localized vibration. Expanded metal has no welds; it is a single continuous sheet. If an intruder cuts one strand, the remaining geometry holds, preventing simple entry.
Yes, our precision tool shop develops custom dies to meet specific structural and privacy demands. We modify SWD, LWD, strand width, and plate gauge parameters to comply with high-security projects (e.g., prison or data center parameters).
For marine areas, we recommend Stainless Steel 316 base panels or Carbon Steel that has been heavily hot-dip galvanized and finished with an architectural-grade PVDF (polyvinylidene fluoride) powder coat. This treatment provides robust protection against chloride ions and high humidity.
Our 2025 heat treatment lines allow us to modify the mechanical properties of carbon steel products. This process enhances structural hardness to HRC 28-32 and raises tensile strength profiles, optimizing the panels to withstand high-impact loads.
We wrap our panel bundles in protective plastic film and secure them on reinforced steel or wooden pallets. Edge protections prevent damage during handling. Each unit includes detailed tags containing tracking information and chemical test results.
