Introduction
Black Annealed Iron Wire is produced by drawing low‑carbon steel rod through a series of dies, followed by an annealing process that softens the wire and imparts a uniform black oxide finish. The annealing treatment enhances ductility, making the wire easy to bend, twist, and tie without cracking. Widely valued for its flexibility and surface friction, Black Annealed Iron Wire is a cost‑effective solution for binding, packaging, and general‑purpose fastening applications in construction, agriculture, and manufacturing sectors.

Features & Advantages
Enhanced Ductility: Annealing reduces hardness and increases elongation, allowing easy bending and forming on site.
Uniform Surface: Black oxide finish prevents rust during storage and gives the wire a non‑slip grip, ideal for secure tying.
Cost‑Effective: Lower material cost compared to galvanized or stainless alternatives, with excellent performance in dry indoor environments.
Excellent Workability: Smooth drawing and consistent diameter ensure reliable feeding in binding machines and manual winding.
Good Weldability: Suitable for spot welding and tack welding when required.
Applications
Black Annealed Iron Wire is commonly used in:
Construction: Rebar tying, brick‑tie, and scaffold binding.
Agriculture: Bale binding, trellis wiring, and greenhouse frame assembly.
Packaging: Carton strapping, palletizing, and bundling of pipes or lumber.
Manufacturing: Wire forming, spring cores, and chassis harness ties.
Crafts & DIY: Fencing repair, art installations, and floral arrangements.
Packaging & Delivery
Packaging:
Coils: Wrapped in moisture‑resistant kraft paper or plastic film, banded with steel straps.
Spools: Mounted on wooden or plastic reels with cardboard flanges.
Cut‑to‑Length: Bundled and shrink‑wrapped or banded for easy handling.
Delivery Lead Time: Standard production and shipment within 10–20 days after order confirmation; expedited service available for urgent orders.
