In modern civil infrastructure, agricultural logistics, and industrial fencing systems, galvanized welded mesh serves as a critical structural component. The engineering community relies heavily on its mechanical stiffness, high weld-point shear strength, and protective zinc passivation layers. As a leading global wholesale galvanized welded mesh exporter, SINSUN Hardware operates at the intersection of metallurgy and industrial logistics, supplying complex commercial requirements with certified structural solutions.
We source high-grade carbon steel rod coils exclusively from XING TAI Steel, ensuring highly uniform chemical structures, predictable tensile strength, and minimal inclusions for perfect resistance welding outcomes.
Utilizing computer-controlled multi-point resistance welders from leading Taiwanese developers, we guarantee high-precision orthogonal joint alignment with optimal fusion depth and zero metal blowout.
SINSUN offers both Galvanized Before Weld (GBW) and Galvanized After Weld (GAW) options, featuring hot-dip zinc bath structures or high-efficiency electro-galvanizing to match varied application life expectancies.
Established in 2006, SINSUN Hardware operates from a modern, integrated 30,000 m² industrial facility. By blending German-imported multi-station cold heading machinery with Taiwanese precision tooling technology, we satisfy challenging global criteria across residential and heavy industrial projects.
Our manufacturing operations maintain robust vertical control, starting from raw material processing using four dedicated spheroidizing annealing furnaces to in-house precision wire drawing. This limits metallurgical deviation, achieving consistent mechanical characteristics: structural hardness ratings of HRC 28-32, dimensional deviations within a strict ±0.02mm window, and tensile strength ranges exceeding 1,000 MPa.
With active export configurations sending more than 8,500 shipping containers to key distribution pipelines annually across the Middle East, South America, Eastern Europe, and Southeast Asia, SINSUN is a trusted structural partner for international buyers.

Standard zinc coatings are being replaced by high-performance zinc-aluminum coatings (Zn-5%Al-MM or Zn-10%Al-MM). These formulations extend the structural life of welded mesh products in highly corrosive marine or industrial settings.
Commercial buyers insist on verifiable compliance. This includes documented mill test certificates and full compliance with international standards such as ASTM A641/A641M, BS EN 10223, and ISO 1461 for hot-dip coatings.
To control job site labor costs, engineers are specifying pre-cut, dimensional mesh panels over roll options. Prefabricated panels improve handling and speed up construction in wall cladding and perimeter security installations.
Our production methodology ensures consistent mechanical characteristics at every point of the mesh matrix. SINSUN Hardware operates an optimized process control system that runs from wire drawing to hot-dip galvanizing.
Understanding the distinction between GBW and GAW is vital for selecting the appropriate product for different environments. In GBW processing, the steel wire is galvanized before it enters the resistance welding machines. While cost-effective, the welding process can burn off the protective zinc layer at the intersection points, leaving small areas vulnerable to atmospheric oxidation.
In contrast, GAW involves welding the untreated bright wire first, then submerging the entire mesh grid into a chemical cleaning bath and a molten hot-dip zinc tank. This coats the entire assembly—including the weld joints—with a uniform zinc layer. This provides excellent corrosion protection, making it ideal for agricultural and industrial applications exposed to moisture and acidic environments.
Every production batch undergoes strict quality control checks to verify compliance. Our laboratory conducts three key tests:
| Property / Dimension | Standard Range Available | Tolerance / Specification | Common Applications |
|---|---|---|---|
| Wire Diameter | 0.5 mm to 8.0 mm | ±0.02 mm (Micro-controlled) | Industrial reinforcement to fine cage mesh |
| Mesh Opening Size | 6 mm × 6 mm to 200 mm × 200 mm | ±0.5 mm pitch consistency | Agricultural partitioning, stucco reinforcement |
| Zinc Coating Thickness | 12 g/m² (Electro) to 600 g/m² (Hot-Dip) | Complies with ASTM A641 & ISO 1461 | Coastal boundary fencing, heavy mining mesh |
| Tensile Strength | 350 MPa to 1100 MPa | Consistent across longitudinal wire paths | Concrete slab crack-control, high-security barriers |
| Shear Resistance | Exceeds 75% of parent wire tensile load | Tested per ASTM A1064 standards | Structural retaining walls and gabion boxes |
SINSUN has evolved from a regional fastener supplier into an integrated manufacturer serving global industrial markets.
SINSUN launched with a dedicated factory focused on high-speed self-tapping screws. This established the engineering foundation for our wire drawing and metallurgical processing operations.
We established our official export department, introducing our products to international markets. This expansion required aligning our production lines with global quality standards.
We installed four spheroidizing annealing furnaces and established in-house wire drawing lines. This allowed us to control material quality starting with the initial wire rods.
We modernized our production facilities by importing multi-station cold heading machinery from Germany and high-precision welding technology from Taiwan.
Production reached an annual output of 36,000 tons. SINSUN shipped over 1,100 export containers to international clients, demonstrating our ability to deliver at scale.
We built a 12,000 m² smart warehouse featuring dedicated spaces for quick-ship stock. This facility supports fast order fulfillment and buffer inventory management.
We added four advanced, continuous heat treatment lines. This in-house capability ensures consistent product temper and mechanical characteristics for all custom orders.
For global distributors and engineering firms, on-time delivery is critical. SINSUN operates an advanced logistics center with a 12,000 m² smart warehouse designed to hold over 18,000 pallets. This layout allows for quick packing, secure loading, and accurate tracking for all shipments.
Our facility handles all stages of prep, including custom packaging, barcode labeling, and moisture-resistant shrink wrapping. This ensures that galvanized welded mesh shipments arrive at the port of delivery in pristine condition, free of rust or handling damage.
By working with major shipping lines, we help protect our partners from fluctuating sea freight conditions. We manage all export documentation and customs compliance requirements directly to ensure a smooth delivery process.
Technical specifications and common questions for galvanized welded wire mesh procurement.
For coastal zones exposed to airborne sea spray, we recommend hot-dip galvanized after weld (GAW) mesh with a minimum zinc coating density of 240 g/m² (approximately 34 microns) or 360 g/m² (approximately 50 microns). This provides a sacrificial zinc barrier that significantly delays the onset of rust compared to standard electro-galvanized coatings.
Our Taiwanese resistance welding equipment uses automated sensors that monitor electrical current and pressure at each weld intersection. This feedback system keeps weld penetration within 15% to 25% of the wire diameter, preventing weak spots or wire thinning.
Yes. We offer customization for sheet sizes, mesh sizes, and borders. Our technical team works with clients to create detailed CAD drawings and structural prototypes. This ensures that the finished panels install correctly and fit the project site dimensions.
Every container shipment from SINSUN includes a complete quality assurance packet. This contains our Mill Test Certificate, compliance reports for ASTM or BS EN specifications, dimensional tolerance records, and zinc coating thickness measurements.
