Black annealed wire is also called black iron wire，soft annealed wire and annealed iron wire.It includes annealed wire and black oiled wire.Annealed wire is obtained by means of thermalannealing. It’s made of carbon steel wire. Annealed wire offers excellent flexibility and softness through the process of oxygen free annealing. And the black oiled wire is formed via the process of wire-drawing, anneal, and fuel oil injection. We can do it into straight cutting wire and also do according to customers' special requirement.

Common diameter range: 0.5mm - 12mm, common specifications such as 1.0mm, 1.2mm, 1.6mm, 2.0mm, 3.0mm, 4.0mm, etc. Special specifications can be customized according to needs.
Product Details
Black iron wire is a product that is not annealed (or only lightly surface treated) after hot-rolled wire drawing. The surface is naturally black oxide, so it is named "black iron wire".
Mainly low-carbon steel, common grades such as Q195, Q215, Q235, etc., with low carbon content (generally ≤0.25%), ensuring a certain plasticity and toughness, suitable for drawing processing.
Common diameter range: 0.5mm - 12mm, common specifications such as 1.0mm, 1.2mm, 1.6mm, 2.0mm, 3.0mm, 4.0mm, etc., special specifications can be customized according to needs.
Bundling and fixing: such as bundling steel bars and wood in construction, bundling straw and branches in agriculture, bundling cartons and pallets in the packaging industry, etc.
Simple processing: making the skeleton of protective nets and isolation fences, the basic materials of handicrafts (such as woven baskets, wire racks), and temporary support structures, etc.
Production Process
Steel rod coil -- Wire Drawing -- Wire Annealing--Rust Removing--Acid Washing-- Boiling-- Drying-- Zinc Feeding-- Wire Coiling.
Product Quality Inspection
In order to ensure product quality, we will arrange professional personnel to check product quality, packaging, weight, hardness, etc., according to customer requirements of product specifications, looking for high-quality and cheap cooperative factories in China, to provide customers with one-stop procurement services and quality assurance.
Packing Shipping
Excellent packaging: waterproof paper and plastic film + iron cover + at least three strapping straps + strapping straps fixed on iron or wood pallets can effectively protect products from corrosion and various climate changes during transportation. Generally speaking, we ship from Shanghai, Tianjin, Qingdao and Ningbo ports. We have worked with many experienced shipping companies for a long time to find the most suitable mode of transportation for you.
