Designed and manufactured under strict ISO guidelines for global infrastructure projects, heavy-duty applications, and custom manufacturing projects.
Why modern infrastructure demands the absolute protection of molten zinc alloy bonding on structural steel wire matrixes.
Hot-dip galvanized welded wire mesh represents the pinnacle of anti-corrosion wire processing technology. Unlike electro-galvanized meshes which carry a thin, superficial zinc coat, the Hot-dip Galvanizing (HDG) process integrates steel wire with molten zinc at approximately 450°C (842°F). This initiates a metallurgical reaction, producing several intermetallic zinc-iron alloy layers (Eta, Zeta, Delta, and Gamma phases) that provide an exceptional barrier against weathering and mechanical wear.
For global procurements, the key differentiator is the choice between Galvanized-After-Welding (GAW) and Galvanized-Before-Welding (GBW). The GAW process is universally recommended by structural engineers for harsh outdoor environments. By welding the raw carbon steel wire mesh structure first and subsequently immersing the complete frame into the molten zinc bath, all weld junctions—which are typically vulnerable points for oxidation—are sealed under a uniform layer of protective zinc. This eliminates the hazard of burn-off spots where rust can take hold, providing three to five times the lifespan of standard GBW meshes.

Get a Quick QuoteExplore our journey of expansion, from establishing exports in 2012 and integrating German technology in 2018, to achieving a 36,000-ton annual output and adding advanced heat treatment lines by 2025.
Sinsun began with a singular focus: to build a factory dedicated to self-tapping screws. This foundational specialization established our core expertise from the ground up.
The year 2012 marked a pivotal step for Sinsun. Our specialized products began reaching customers across the world, expanding our mission beyond borders.
Added four spheroidizing furnaces for raw material processing and in-house wire drawing capabilities, ensuring control from the raw material stage.
Enhanced production with new German multi-station cold heading machines and grew our product line to include structured drill tail screws.
Defined by two metrics: reaching 36,000 tons in annual production and fulfilling international orders with over 1,100 export containers.
Operate a dedicated ready-stock warehouse to ensure timely delivery for our clients and meet routine supply needs efficiently.
Significantly boosts our production capacity, translating to greater consistency in product quality and stronger guarantees for on-schedule delivery.
How macro-economic changes, automation, and strict environmental standards shape the future of Hot-dip Galvanized Welded Wire Mesh.
Modern engineering relies on high-speed multi-station mesh welding machinery. Electronic control systems adjust the pressure and weld time per millisecond, ensuring no wire necking occurs. This preserves the wire's raw tensile strength (exceeding 550 MPa) at every joint intersection.
Infusing trace quantities of Aluminum, Magnesium, and Nickel into the galvanizing bath creates an advanced zinc-alloy layer. This significantly improves corrosion resistance, achieving up to 1,500 hours of continuous salt spray test resistance with a thinner, lighter coating.
Global standards, including RoHS and REACH, are driving manufacturers to implement lead-free hot-dip galvanizing lines. By keeping lead concentrations below 0.1%, we guarantee that our structural and agricultural wire meshes are completely safe for sensitive ecological soils and water systems.
Our high-durability hot-dip galvanized welded wire mesh products serve critical roles across primary industrial sectors globally. Sinsun's engineering grade solutions address environmental and structural challenges in the following fields:
We ensure that Sinsun products meet local national standards in importing regions. From ASTM standards in North America to EN regulations in Europe and GOST in Russia, our products carry official quality certifications.
Our regional warehouse and multi-lingual logistics support team manage custom clearance, duty calculations, and intermodal transport schedules, ensuring seamless port-to-door delivery.
At SINSUN, our quality control begins at the source. We start with premium raw materials from XING TAI Steel, then perform in-house spheroidizing annealing and precision wire drawing in our own plant.

Hot-dip galvanizing involves immersing the mesh in molten zinc, creating a thick (over 244 g/m²) zinc-iron alloy layer that chemically bonds with the steel. This provides physical protection and prevents corrosion. In contrast, electro-galvanization applies a thin (under 45 g/m²) layer of zinc that can easily scratch off, making it suitable only for dry indoor environments.
During the welding process, temperatures exceed 1200°C. If you weld pre-galvanized wires (GBW), the protective zinc coating at the weld joint burns off, leaving the steel exposed to moisture and oxygen. With GAW, the entire mesh grid is welded first, and then the complete assembly is hot-dip galvanized. This seals every weld point under a layer of protective zinc.
We source our steel coils directly from Xingtai Steel, a leading manufacturer of high-tensile wire rod. In our own production facilities, we perform in-house spheroidizing annealing and multi-stage precision wire drawing. This control over the raw material ensures high ductility, structural uniformity, and tensile strength across all our wire mesh products.
Sinsun operates a 30,000 sqm production facility equipped with advanced manufacturing machinery and our own heat treatment lines. Coupled with our 12,000 sqm smart warehouse, we maintain raw material and standard component inventories to support reliable scheduling, consistent lead times, and fast shipping logistics for bulk orders.
