Galvanized Steel Wire for Optical Cable
Galvanized Steel Wire for Optical Cable is made to produce the optical cable. The specification is usually customer-made. The metallic zinc coatings applied by the galvanizing process are an effective way of combating corrosion in steel. Galvanized wire for general manufacturing purposes is available in an En 10264 Class B coating.

Galvanised Wire Working Specifications
Given that galvanized wire is classified according to the amount of zinc coating, the following table outlines the difference between tensile strength.

Diameter Properties
Standard Galvanized Wire is manufactured to comply with the following diameter tolerances:
Nominal Wire Diameter | Tolerance (mm) |
over 0.60mm up to and incl. 1.00mm over 1.00mm up to and incl. 1.80mm over 1.80mm up to and incl. 2.00mm | +/-0.015 +/-0.02 +/-0.025 |
Steel Chemistry
A combination of steel grades is used and heat treatment processes to manufacture soft, medium and hard tensile grades. The table below is indicative only of steel chemistries used.
Tensile Grade | % Carbon | % Phosphorus | % Manganese | % Silicon | % Sulphur |
Standard | 0.45~0.50 | 0.032 | 0.5 ~1.00 | 0.10~0.34 | 0.041 |
