Tianjin Guoyu Steel Co., Ltd. specializes in high-precision hot-dipped galvanized flat steel wire, engineered with refined cold-rolling and flattening processes. Our products deliver superior zinc-bond strength and long-term corrosion resistance, ensuring seamless performance in high-speed industrial stitching, heavy-duty binding, and demanding construction environments.
Product Overview:
Our Galvanized Flat Steel Wire is engineered for high-performance industrial applications. Combining the strength of premium low-carbon steel with advanced galvanizing technology, it offers exceptional dimensional stability and corrosion resistance. Whether for high-speed carton stitching or intricate metal crafts, our wire ensures smooth operation and a professional finish.
Dimensions:
Thickness: 0.30mm – 1.50mm (Precision Tolerance: ±0.02mm)
Width: 1.00mm – 5.00mm
Material: High-quality Q195 / Q235 Low Carbon Steel or as required
Zinc Coating Options:
Electro-Galvanized: 15-25g/m² (Mirror-bright surface, ideal for display products)
Hot-Dipped Galvanized: 40-200g/m² (Superior rust protection for outdoor use)
Mechanical Properties: Tensile Strength: 350-950 N/mm² (Customizable temper from soft to hard)
Burr-Free Smooth Edges: Our precision rolling process ensures rounded, smooth edges that won't damage your machinery or scratch operators.
Anti-Flaking Coating: The zinc layer is tightly bonded to the steel core, preventing peeling even under extreme 180° bending or high-speed forming.
Perfect Consistency: Zero variations in width and thickness across the entire coil, reducing downtime caused by wire jams in automated production lines.
Excellent Ductility: Easy to weld, bend, and shape without compromising structural integrity.

Packaging Industry: Heavy-duty stitching wire for corrugated boxes, books, and wooden cases.
Hardware & Home: High-quality clothes hangers, storage racks, and gardening tools.
Construction: Flexible connectors, reinforcement mesh, and binding systems.
Filtration: Support frames for industrial filters and oil strainers.
