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

Black annealed wire from Anping Hongchaoda Wire Mesh Co., Ltd. is a low-carbon steel wire that has undergone controlled heat treatment to achieve maximum ductility and a uniform dark oxide surface. The annealing process, conducted at temperatures typically between 700 degrees Celsius and 750 degrees Celsius, reduces internal stresses and increases the wire's malleability for cold forming and tying operations. This product is drawn to precise gauge dimensions and supplied in coils or spools for construction contractor and industrial manufacturing use across Hebei Province and international markets.

The material starts as Q195 or Q235 low-carbon steel rod, with carbon content typically below 0.25% to ensure the softness required for hand tying and machine binding without fracture. During production, the wire is drawn through successive dies to achieve target diameters, then annealed in a controlled atmosphere to prevent decarburisation and maintain a consistent black oxide layer that offers limited corrosion protection. Standard gauges range from BWG8 to BWG22, with tensile strength after annealing typically falling between 350 MPa and 500 MPa depending on final diameter and processing parameters. Surface finish is smooth and free from excessive scale, though slight oil residue from the drawing lubricant may be present.

Buyers in construction, agriculture, and packaging sectors use this wire for reinforcing bar tying, vineyard and orchard trellis installation, bale binding, and general fabrication where ease of bending and knotting outweighs the need for high tensile strength. The wire responds well to manual twisting and mechanical fastening, and its softness reduces worker fatigue during extended tying operations. When sourcing from Anping Hongchaoda Wire Mesh Co., Ltd., located in Yantuan Industrial Zone, Hengshui, Hebei, importers should confirm coil weights, inner diameters, and packaging specifications directly with the supplier, as these details are not specified in the available listing data.

Anping Hongchaoda Wire Mesh Co., Ltd. operates from Yantuan Industrial Zone in Hengshui, Hebei Province, a region with established concentration in wire mesh and metal product manufacturing. The supplier is classified under an imported tier and holds a harbor trust designation, indicating a verified business registration with platform-level documentation rather than full third-party audit coverage. The listing shows a response rate of 0.00% with zero average response hours recorded, which suggests either a new account, limited engagement with inbound enquiries through this channel, or data capture issues that buyers should investigate before relying on this supplier for time-sensitive procurement.

The company profile does not disclose production capacity, workforce size, annual revenue, export history, or specific quality management certifications held. No ISO, SGS, or other third-party certification details are confirmed in the sourced data, despite generic references in marketing material. Buyers should request copies of current mill test certificates, quality management system documentation, and export licence verification directly from Anping Hongchaoda Wire Mesh Co., Ltd. The address places the manufacturer within the broader Anping County wire product cluster, which provides access to raw material supply chains and established logistics corridors to Tianjin Port for seaf exporting.
