From standard agricultural wire to application-specific requirements, WANLIN METAL provides flexible steel wire solutions based on your required material, diameter, surface treatment and specifications.
Factory Advantages
Through multi-pass cold drawing and controlled processing, we maintain precise wire diameters and consistent dimensional tolerances for reliable downstream processing.
Controlled drawing, lubrication and heat-treatment processes help achieve consistent mechanical properties, with a balanced combination of tensile strength and ductility.
Saponification, rinsing and controlled drying processes help deliver a clean, smooth and uniform wire surface, reducing surface defects and supporting reliable subsequent processing.
From raw material sorting and re-inspection to finished product inspection, quality is controlled at multiple stages to ensure stable and consistent product quality.
With controlled cold drawing, straightening, shaping and wire coiling processes, we can produce steel wire according to different diameter, mechanical and processing requirements.
Wastewater collection, neutralization, sedimentation and recycling are integrated into the production process, supporting responsible and controlled manufacturing.
Steel Wire Manufacturing & Supply
We are a direct steel wire manufacturer and export supplier, with our own production facility in China. Our manufacturing team manages key processes including raw material control, wire drawing, surface treatment and quality inspection, allowing us to provide stable factory-direct supply and customized production for global customers.
To provide an accurate quotation, please send us the wire material/grade, diameter, tolerance, tensile strength, surface treatment, coil weight, quantity, packaging requirements and destination port. Drawings, technical specifications or product samples are also helpful if available.
We supply a range of carbon steel and spring steel wires for industrial applications. Common grades include 65#, 70#, 65Mn, 72A, 72B, 77B, 82A and 82B. Material selection can be confirmed according to the customer’s application and performance requirements.
Our precision wire drawing process allows standard diameter tolerance to be controlled to approximately ±0.02 mm, depending on the material, diameter and production requirements. Tighter tolerances can be discussed for specific applications.
Yes. We can provide small-coil samples for customers to evaluate wire dimensions, surface condition and mechanical performance, as well as conduct actual machine or production-line testing before placing a bulk order.
Yes. We support customized production based on customer requirements, including wire diameter, tensile strength, tolerance, coil weight, surface treatment and packaging.
Depending on the product and customer requirements, we can provide relevant inspection records, material information and quality documentation. Batch information can also be retained to support product traceability.
MOQ and lead time depend on the material, diameter, tolerance, surface treatment, quantity, packaging and customization requirements. We support sample testing, trial orders and regular production according to customer needs.
