Black Iron Wire -
We provide two types of black iron wire: black brushed wire and soft black annealed iron wire. Black brushed steel wire is a hard drawn carbon steel wire suitable for mesh weaving, fence, iron nail, galvanized or lashing applications. Black annealed wireis mainly used as a bonding material in construction or daily use.
Material: high-quality low-carbon steel wire or iron wire.
Features: coated with anti-rust oil, low cost and economical.
Weaving method: black wire drawing: wire drawing-coiling or cutting-anti-rust spray
Annealed wire: wire drawing-annealing-coiling or cutting-anti-rust spray
Others: coiled wire, large package, cuttable and U-shaped wire.
Black annealing line for civil construction:
The annealing of bare wires (simple drawn wires) can be done in batches (bell furnace) or on-line (on-line furnace).
The purpose of annealing is to restore the ductility of the wire that it lost during the stretching process.
Annealed wire is stored in coils or spools of different weights and sizes, depending on its use and customer needs. We offer two types of annealing lines, bright annealing lines and black annealing lines. The black annealed wire is named for its pure black color. The soft annealed wire provides excellent flexibility and softness through an oxygen-free annealing process.
