Messenger Wire
Galvanized Wire is made to ASTM B498; ASTM A 475; BS 183 etc. The metallic zinc coatings applied by the galvanizing process are an effective way of combating corrosion in steel. Galvanized wire for cable application is available in a Class A coating; Class B coating and Class C coating.
Class A coatings are smoother, however less corrosion resistant than heavy galvanized coatings and are often used in normal wire working applications. Some typical end users include cages, bucket handles, coat hangers and baskets.
Class B and Class C coatings are used in conditions where atmospheric corrosion is severe. End users include crop support wires where chemicals are used, pool fencing or chain mesh in coastal areas.

Galvanised Wire Working Specifications
Given that galvanized wire is classified according to the amount of zinc coating, the following table outlines the difference between standard, heavy galvanized and extra-high galvanized wire.
