Low Carbon Black Annealed Iron Wire 0.4mm To 4mm For Building Binding Wire
Black annealed wire, which is made of low carbon steel or iron, is often applied for weaving, baling in home use and construction. For example, baling hay in agriculture area. Black annealed wire is mainly processed into coil wire, spool wire or big package wire. Or further straightened and cut into cut wire and U type wire. Compared with black iron wire, black annealed wire is more softer and has higher flexibility.Black annealed wire, which is made of low carbon steel or iron, is often applied for weaving, baling in home use and construction.

Black Annealed Iron Wire Production Process:
The Q195 wire rod drawing model into the black iron wire, through 1000° high temperature firing, black iron wire after annealing treatment, soft wire, can increase the wire tensile degrees.

Black Annealed Iron Wire Type:
According to the packaging, there are coil wire, U-shaped wire, loop tie, and cutting wire.
1. Wire coil. It is the most common packaging type of steel wire. The coil weight ranges from 10 kg to 1,000 kg, which is easy to transport. Also, you can cut it into the desired size during use.
2. U-shaped wire. This kind of wire is perfect for binding threaded steel bars in the construction industry. In addition, it often uses 20# or 21# wire and the popular length is 250 mm to 600 mm. It can not only save manpower but also reduce waste.
3. Loop wire ties. We offer double loop tie wire and single loop tie wire. The former has two preformed loops, while the latter has one preformed loop and one straight end. The wire ties can quickly and securely tie bags, cables, rebar, and pipes.
4. Cutting tie wire. It is cut to a fixed length after straightening, which can be customized according to the specific requirements of customers. And it is easy to transport and use.
