3.1 wire rod
hot rolled steel delivered in coils, used for cold working treatments such as wire drawing
3.2 bare steel wire
product manufactured by cold working wire rod (3.1) that is in a suitable metallurgical condition for cold working
3.3 hot-dip zinc coated steel wire
hot-dip galvanized coated steel wire
steel wire that is coated with zinc in a bath of molten zinc
3.4 zinc-aluminium coated steel wire
steel wire that is coated with zinc-aluminium alloy in a bath of molten zinc-aluminium alloy
Note 1 to entry: In this document, “steel wire” or “wire” refers to zinc or zinc-aluminium coated steel wire, unless otherwise specified.
3.5 stabilized wire
steel wire that is given a final thermo-mechanical treatment
3.6 out-of-round
arithmetic difference between the maximum and minimum diameters of the steel wire at the same cross section
3.7 semi-parallel wire cable
specified number of steel wires bundled together with a maximum lay angle of 4°
Note 1 to entry: Semi-parallel wire cables are usually used for cable stayed bridge and suspenders for suspension and arch bridges.
3.8 unit of manufacture
coil of steel wire produced from one coil of wire rod (3.1)
3.9 unit of product
