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

Black annealed wire from Anping Yuanda Metal Products Factory is a low-carbon steel wire that has undergone thermal annealing in an oxygen-free environment to achieve exceptional ductility and a soft, workable finish. The factory produces wire ranging from gauge 5 to gauge 38, with coil weights spanning 5 kg to 500 kg bundles, and offers straight-cut, U-type, and custom-formatted variants to match specific binding requirements. The material begins as carbon steel wire or iron wire, then passes through wire-drawing, annealing, and optional fuel-oil injection to yield either standard black annealed wire or black oiled wire for added corrosion resistance during storage.

The annealing process eliminates internal stresses from cold drawing, reducing hardness and increasing elongation so the wire can be twisted and tied without fracturing. Typical tensile strength for fully annealed low-carbon wire of this class falls between 350 MPa and 500 MPa, though the supplier does not publish certified mechanical test reports. Surface finish is matte black from the oxide scale formed during annealing; the oiled variant receives a light petroleum-based coating to retard atmospheric rust. Wire diameter tolerances for general construction-grade annealed wire commonly conform to EN 10218-2 Class T2 or equivalent, but buyers should request a mill test certificate to confirm compliance.

Civil construction contractors use this wire for tying rebar cages and formwork, while agricultural operations deploy it for baling hay and securing silage. Parks-interest groups and hardware distributors also stock it for daily binding tasks. The factory states willingness to manufacture to customer orders, suggesting some flexibility in coil dimensions and cut lengths. Importers should verify whether Anping Yuanda produces the wire in-house or sources from sub-contractors in Hebei Province's dense wire-mesh cluster, as this affects consistency and certification availability.

Anping Yuanda Metal Products Factory is located at Zhuye High-Tech International on Changjiang Road in Shijiazhuang, Hebei Province, postal code 050000. The supplier is classified as an imported-tier vendor with a harbor trust tier, and its response rate stands at 0.00% with no recorded average response hours, indicating limited or unmonitored buyer engagement through the platform. The listing describes in-house manufacturing capability across annealing, wire-drawing, oil injection, and cutting processes, but no third-party factory audit, ISO certification, or quality system accreditation is mentioned.

The company's product scope centres on black annealed wire in multiple coil formats and weights, with explicit mention of custom manufacturing according to customer orders. No information is provided about annual output, number of production lines, export licence details, or key account clients. The dense concentration of wire and mesh producers in Anping County and greater Shijiazhuang suggests potential for both competitive sourcing and supply-chain complexity; buyers should conduct direct due diligence to confirm production ownership and quality control protocols.
