This specification covers five grades of zinc-coated, steel wire strand, composed of a number of round, steel wires, with four weights of zinc coatings, suitable for use as guys, messengers, span wires, and for similar purposes.
The base metal xstm be steel made by any commercially accepted steel making process and of such quality and purity that, when drawn to the size of wire specified and coated with zinc, the finished strand and the individual qstm shall be of uniform quality and have the properties and characteristics as prescribed in this specification.
It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.
The zinc-coated wire shall be capable of being wrapped in a close helix without cracking or delaminating the zinc coating. Class 1 and Classes A, B, and C.
