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

Supire Steel Wire Company produces annealed tie wire in both black and bright finishes for industrial and agricultural use. The wire is made from carbon steel and undergoes thermal annealing to restore ductility lost during drawing. Available diameters range from 0.71 mm to 4.5 mm, corresponding to gauges 7 through 22. Tensile strength is specified between 30 kg/mm² and 50 kg/mm². Coils are packed from 10 kg to 200 kg, each wrapped in a plastic bag and encased in a hessian or woven cloth sleeve.

The black variant offers high flexibility and elongation, while the bright variant provides a smooth, reflective surface suitable for visible tie work. In the industry, annealed tie wire commonly conforms to ASTM A108 carbon steel grade, which gives good weldability and corrosion resistance when oil‑painted. Standard practice for electro‑galvanised versions applies a zinc coating of 8 - 25 g/m², although this coating is not listed for Supire’s black wire. Annealing temperatures typically lie between 650 °C and 750 °C, producing an elongation of about 30 % in standard tests.

Primary customers include construction firms for rebar bundling, farmers for hay baling, and fabricators of wire mesh or crafts. The wire can be further processed into straight cut lengths or U‑shaped ties according to buyer specifications. Buyers should confirm minimum order quantity, incoterms and payment conditions directly with Supire, as these details are not disclosed in the listing.
