Import Black Iron Wire — Buy in Bulk from Supplier in China

Black iron wire, also called annealed steel wire, is a low-carbon steel product that undergoes heat treatment to achieve a soft, ductile state suitable for bending and tying operations. Hebei Hengyang Stainless Steel Products Co.Ltd supplies this material from their facility in Anping, Hebei Province, a region with established wire-manufacturing infrastructure. The wire is drawn to gauge from mild steel rod and then annealed in controlled atmosphere furnaces to relieve internal stresses and produce the characteristic black oxide surface finish. Available gauges span from fine binding wire up to heavier construction grades, with exact diameter tolerances to be confirmed with the supplier for each order.

The annealing process gives black iron wire its distinctive dark surface, a layer of iron oxide that provides moderate corrosion protection in dry environments though additional coating may be needed for outdoor exposure. The material grade is typically Q195 or Q235 low-carbon steel (typical carbon content 0.06-0.22%), offering yield strength around 195-235 MPa in the as-supplied soft condition. Hebei Hengyang's wire is supplied in coiled form, with standard coil weights and inner diameters that vary by gauge. The softness rating, measured by reverse bend tests or elongation percentage, determines suitability for machine tying versus hand application. Annealed wire differs from galvanized or PVC-coated alternatives in its lower cost and greater flexibility, though it sacrifices long-term weather resistance.

Primary buyers include construction contractors for rebar tying and formwork fastening, agricultural operations for fence assembly and vineyard trellising, and manufacturers of wire products such as hangers, baskets, and mesh. The wire can be further processed by point grinding, cutting to length, or straightening for specific end uses. Importers should verify whether Hebei Hengyang offers cut-and-bent bundles, plastic spool winding, or bulk coil packaging to match their handling equipment. Payment terms, Incoterms, and minimum order quantities are not stated in the listing data and must be negotiated directly with the supplier.

Hebei Hengyang Stainless Steel Products Co.Ltd operates from the Development Zone in Anping County, Hengshui, Hebei Province, China. Anping is recognised as China's principal wire mesh and wire products manufacturing cluster, with decades of accumulated supplier density and logistics infrastructure. The company is classified as an imported supplier tier with harbor trust tier status on the platform. The listing shows zero response rate and zero average response hours, indicating no tracked inquiry activity or that response data has not been populated. No workforce size, annual revenue, year of establishment, or specific factory certifications are stated in the source profile.

The supplier's registered address places them within Anping's industrial zone, though the listing does not specify whether they own production facilities or operate as a trading intermediary. Their product focus covers stainless steel and carbon steel wire products. Buyers should request factory audit reports, ISO 9001 certificate validity dates, and production capacity figures directly. The lack of response metrics suggests either a new listing or limited platform engagement, so direct communication channels and third-party verification become essential due-diligence steps.
