Explore our range of heavy-duty concrete screws, razor barbed wires, high-durability wood screws, and specialized fastness systems manufactured under ISO 9001 compliance standards.
Sinsun Hardware, established in 2006, is a premier manufacturer and global supplier of high-quality fasteners and structural wire products. Operating from our expansive 30,000 sqm integrated facility in Northern China, we produce a extensive portfolio of structural nails, precision engineered screws, high-tensile wires, and heavy-duty rivets. Driven by our dual core competence in advanced German multi-station cold heading machinery and precision Taiwanese manufacturing techniques, Sinsun guarantees consistent tolerances, exceptional metallurgy, and outstanding physical integrity.
Our facility houses a state-of-the-art 12,000 sqm smart warehouse maintaining over 18,000 pallet capacity. This automated infrastructure facilitates the reliable distribution of more than 8,500 shipping containers annually across crucial world markets, including the Middle East, South America, Russia, and Southeast Asia.
Utilizing high-end cold heading equipment imported directly from Germany, Sinsun processes wire and fasteners with micro-dimensional accuracy (±0.02mm). We execute a minimum of 12 internal quality checks, confirming corrosion protection ratings (reaching 1,000+ hours in salt spray testing) and tensile properties.
Our raw structural feed is sourced exclusively from XING TAI Steel. By handling raw rod spheroidizing annealing and subsequent multi-stage wire drawing in-house using automated gas-fired heat treatment furnaces, we sustain a seamless control matrix over both the carbon microstructure and structural uniformity.
High-Tensile Galvanized Wire represents a milestone in structural steel engineering. In agricultural, fencing, construction, and power transmission sectors, high-tensile wire must withstand continuous load margins, seismic vibrations, and aggressive atmosphere challenges. Our raw wire rods, derived from specialized carbon steel (C60 to C85 grades), undergo a series of thermal treatments to establish a homogeneous pearlite microstructure. This microstructure allows the wire to endure deformation during cold drawing without developing micro-fissures.
The anti-corrosive characteristics of our galvanized wire rely on hot-dip galvanization chemistry. Passing steel wire through molten zinc (maintained at 450°C) initiates a diffusion process. This forms zinc-iron alloy phases (Gamma, Delta, Zeta) topped by a pure Zinc outer envelope (Eta layer). This alloy configuration provides barrier protection and sacrificial galvanic protection, resisting corrosion even if the wire surface is scratched.
Engineered to deliver tensile strengths ranging from 900 MPa up to 1,800 MPa, our high-tensile wires preserve their mechanical performance under stress. Despite this rigidity, the wire undergoes continuous reverse bend testing and torsion evaluations to verify that ductility limits are not compromised. Our wires remain flexible enough for vineyard installations and high-density security configurations without fracturing.
High-carbon steel wires are susceptible to hydrogen embrittlement during pickling. At Sinsun, we implement an acid cleaning cycle featuring proprietary pickling inhibitors, followed by controlled thermal degassing. This baking step drives out atomic hydrogen from the steel lattice, preventing sudden failures under sustained mechanical loads.
Global procurement teams in infrastructure, agriculture, and industrial security are shifting their focus from basic material cost to long-term lifecycle savings. High-tensile galvanized wire applications are transitioning toward more sustainable coatings and higher strength-to-weight ratios to optimize material usage and minimize freight costs.
The industry is rapidly adopting Zinc-Aluminum-Magnesium alloy coatings. Offering up to four times the corrosion protection of standard zinc coatings in C5-M marine environments, Zn-Al-Mg alloys allow for thinner protective layers, reducing zinc consumption while extending structural lifespan.
Large-scale projects demand guaranteed logistical reliability. With our 12,000 sqm automated warehouse, Sinsun maintains strategic buffers of high-demand sizes, shielding global distributors and agricultural cooperatives from supply chain disruptions.
Environmental regulations demand clean, eco-friendly metal processing. Our manufacturing plants implement closed-loop acid reclamation processes and zero-effluent wastewater treatments, keeping our production practices in line with global ESG requirements.
Our manufacturing integration allows Sinsun Hardware to deliver customized solutions for diverse structural demands across major industrial sectors.
High-tensile wire for vineyard trellising and modern crop support systems. Low-elongation properties minimize wire sag over time, reducing retensioning maintenance costs.
Used as core wires for razor wire production and structural mesh fences. Resists impact forces and manual cutting tools, securing utility hubs and national borders.
Provides critical mechanical armoring for subsea and underground power cables, shielding delicate conductors from pressure stresses and marine corrosion.
High-tensile structural wire configurations designed for pre-stressed concrete beams, reinforcing bridge spans and heavy building foundations.

Sinsun continues to invest in metallurgical research and process automation. Our engineering teams are working on next-generation coating options and automated manufacturing adjustments to meet evolving international requirements.
We are refining drawing parameters to produce high-tensile wires exceeding 2,000 MPa tensile strength, maintaining necessary ductility through localized thermo-mechanical treatments.
Integrating in-line electromagnetic sensors to scan wire structural uniformity during high-speed drawing, detecting internal micro-defects before final coating stages.
Transitioning toward cobalt-free and low-acid passivation lines, ensuring our manufacturing sites comply with the latest European chemical regulations (REACH).
Shipping raw wires and fasteners across long distances requires robust packaging and clear documentation. Sinsun protects products against marine salt corrosion, humidity shifts, and physical transit stresses through specialized packaging configurations.
Every wire coil and fastener container is wrapped in Volatile Corrosion Inhibitor (VCI) films, creating a molecular protective layer that prevents surface oxidation during ocean transport.
We offer customized coil weights (ranging from 50kg to 1000kg), custom payoff stands, and barcode labeling tailored for direct warehouse integration and automated inventory scanning.
Every shipment is accompanied by Mill Test Certificates (MTC) matching EN 10204 3.1 standards, providing trace details from raw steel melt to final tensile testing.
