The wires we manufacture can generally be divided into four groups: bright wires, annealed wires, coated wires, and stainless wires.
Bright iron wire is wire drawn hard with dry lubricants. On its surface there is a thin lubricant layer, which prevents rusting to some extent.
Annealed iron wire is heat-treated after drawing. It is softer, more flexible, and tougher than bright wire.
Coated iron wires are wires treated with different galvanizing methods. After drawing, the wire passes through molten zinc, causing a zinc layer to adhere to the surface of the wire. The wire can then be either light galvanized (40–120 grams of zinc per square meter) or heavy galvanized (180–350 grams of zinc per square meter). This hot-dip galvanizing process provides iron wire with effective protection against rusting.
Iron wire can also be electro-galvanized or copper-coated, in which case the wire surface is beautifully shiny, smooth, and clean. However, such a coating does not protect the wire from rusting as effectively as hot-dip galvanizing.
Plastic-coated wire is made by pressing a PVC plastic layer onto the wire surface with a plastic-coating machine.
