Binding wires are made of galvanized, plastic coated annealed and stainless steel wire. It is softness, good ductility and high strength, and is easily bent and tied in a knot. Binding wire with heat treatment will have high strength and become softer. Cover the wire with zinc, its resistance to corrosion will be strength. Galvanized binding wire has a matte or shiny finish, and it is easy to oppose the negative effects of the environment. PVC coated binding wire has resistance to corrosion. Manufacturing technology of baling wire consists of two stages. In the first stage are made of steel billets, and burn it, and the second – passed under high pressure through a hole by drawing. It has a circular cross section. Binding wire without coating has a diameter of 0.16 mm – 2 mm, and coated diameter from 0.2 mm to 2 mm. The most common use diameter is 0.8 mm, 1 mm and 1.2 mm.
