Sinsun Hardware, established in 2006, is a leading manufacturer and global supplier of high-quality fasteners and perimeter systems. As Northern China's largest producer of Self-Tapping Screws, we operate from a gigantic 30,000 sqm integrated facility that includes modern production zones, a 12,000 sqm smart warehouse with an 18,000+ pallet capacity, and multi-language customer support centres. Our yearly supply of over 8,500 containers consistently services key global markets such as the Middle East, Southeast Asia, South America, and Europe.
We provide vertical supply chain superiority. By combining specialized fastener manufacturing with premium raw material processing, we ensure every structural mesh installation is supported by structural fasteners engineered for durability, shear strength, and extreme environmental resilience.
Welded mesh fencing systems have transitioned from passive security enclosures to dynamic infrastructure assets integrated with modern construction frameworks. In the global landscape, rapid urbanization and high-security facility updates dictate the demand for mesh fencing that combines extreme rigidity, anti-climb properties, and long-term corrosion resistance.
As a global industry-leading supplier, we analyze the application vectors across three macro-industry segments:
For nuclear plants, military parameters, and correctional facilities, we supply dense-mesh configuration fencing (358 mesh style). Designed to resist hand tools and heavy-duty wire-cutters, this system integrates with ground sensors and physical barriers to secure high-risk zone perimeters.
Expressways, mass transit railways, and regional airport boundaries require cost-efficient, high-tensile wire fencing. Our systems feature protective organic PVC coatings and hot-dip galvanization to withstand continuous weather exposure, cross-wind forces, and vibrations.
Internal factory segregation, logistics park boundaries, and urban community dividers rely on our flexible panels. They feature modular post systems and structural fixing anchors to support rapid installation and seamless layout modifications.
Our production capabilities are driven by German-imported multi-station cold heading machinery, precision Taiwanese technology, and a highly specialized technical workforce. We optimize structural component tolerances and chemical properties to support reliable construction integration.
Every single batch of our structural wire, fasteners, and welded mesh components undergoes 12+ stringent quality checks to guarantee the following operational parameters:
We specialize in providing unique fastening and perimeter structural designs tailored to custom industrial projects. Our engineering division collaborates directly with developers from layout concept to final delivery, ensuring that customized wire gauges, structural meshes, post designs, and surface finishes strictly adhere to targeted design metrics.
With automated machinery line-ups and vertical integration from spheroidizing annealing furnaces to wire-drawing divisions, Sinsun ensures continuous quality control at the source. This eliminates structural variability and shortens production lead times for large-scale international contracts.
Get a Quick QuoteExplore our journey of development since 2006: expanding export channels in 2012, implementing German cold-forming technology in 2018, and scaling output to over 36,000 tons with advanced heat treatment lines in 2025.
We began with a singular focus in 2006: to build a factory dedicated to self-tapping screws. This foundational specialization established our core expertise from the ground up, guaranteeing optimal support systems for wire, mesh, and structural assembly components.
The year 2012 marked a pivotal step for Sinsun. With the establishment of our dedicated Export Department, our specialized fasteners and metal systems began reaching civil construction and perimeter fencing projects across continents.
We expanded quality control by adding four spheroidizing furnaces for raw material processing and in-house wire drawing capabilities. This strategic upgrade allowed us to control every step of production starting from the raw rod phase.
Our production capability was enhanced in 2018 with new German multi-station cold heading machines. Concurrently, we expanded our product lines to include specialized drill tail screws, securing high-precision hardware matching our fencing and structural assemblies.
Sinsun achieved 36,000 tons in annual production, fulfilling international orders with over 1,100 export containers. This established our capability to sustain large volume orders for commercial and governmental contracts.
To support distribution networks, we established a 1,200-square-meter ready-stock warehouse. This facility supports fast shipping of standard specifications, helping project managers maintain strict build schedules.
The addition of four automated heat treatment lines significantly boosts our capacity. This directly translates to greater consistency in metal tempering, tensile performance, and mechanical reliability of our structural anchors and wire products.
In the US and Canadian markets, security fencing systems must conform to ASTM F2453 (Standard Specification for Welded Wire Mesh Fence Fabric) and ASTM F1043 (Strength and Protective Coatings on Steel Industrial Chain Link Fence Framework). Our manufacturing lines ensure galvanized-before-welding (GBW) and galvanized-after-welding (GAW) options meet Class 1 and Class 2 coating weights to prevent accelerated oxidation in coastal regions.
For European construction zones, compliance with EN 10223-4 (Steel Wire and Wire Products for Fences - Welded Mesh Fencing) is required. Our panels are engineered to meet strict dimensional tolerances on wire diameter, aperture spacings, and weld shear strength. We use certified organic coatings (powder coating & PVC coatings according to EN 10244-2) to ensure UV stability and environmental safety.
Industrial fencing deployed in GCC countries faces intense solar radiation and high temperatures. Sinsun utilizes high-density polyester powder coatings (electrostatic thermosetting coating) with customized UV blockers to prevent fading, cracking, and chalking, maintaining structural integrity in arid regions.
Coastal airports, dockyards, and port perimeters rely on marine-grade protection. Our products, including SS316 stainless steel lag screws, concrete anchors, and heavily galvanized wires, withstand salt spray exposure, reducing maintenance overhead in corrosive offshore environments.
We welcome clients for on-site factory visits, demonstrating our manufacturing scale and quality control systems. We participate in global industry exhibitions to showcase our latest fastening and fencing components.
The next generation of welded mesh fencing integrates physical barriers with electronic detection systems. At Sinsun, we are adapting our production lines to accommodate the shifting requirements of intelligent perimeter security.
Our future development centers on three main objectives:
Implementing dry powder coating lines that minimize chemical waste while maintaining resistance in salt-spray tests.
Deploying robot-assisted welding cells for customized mesh gates, post assemblies, and heavy-duty structural anchor plates.
Developing structural mesh lines with pre-engineered pathways for fiber-optic cabling and anti-climb sensor installations.
Hot-Dip Galvanized (HDG) welded mesh involves dipping raw steel panels in molten zinc, creating a thick, durable zinc-iron alloy layer (usually between 40-100 μm). This provides heavy-duty protection suited for outdoor and industrial use. Electro-galvanized mesh uses a thinner electroplated zinc layer (typically 5-15 μm), which has a smoother appearance but is best suited for dry, indoor settings or temporary sites.
Weld shear strength determines the structural integrity of the fencing panel when subjected to external impact, wind loads, or climbing forces. According to international standards, the weld joint must withstand a shear force equal to at least 50% of the wire's minimum tensile breaking strength. Sinsun uses automated spot welding to ensure consistent weld fusion, preventing joints from popping under mechanical stress.
We provide custom solutions from design to delivery. We produce custom wire gauges, panel dimensions, post profile layouts, and installation hardware. Additionally, our 12,000 sqm warehouse holds standard stocks to help maintain short delivery times for complex infrastructure projects.
Chemical composition and coating uniformity are key to durability. We use high-grade medium carbon steel rods sourced from Xingtai Steel, combined with automated heat treatment. Fasteners for outdoor structural mesh receive premium zinc coatings or are produced from marine-grade stainless steel (SS304/SS316) to resist corrosion from humidity, acid rain, and airborne salts.
