Quantity:

Galvanized steel wire strand refers to any steel wire product which is subjected to a galvanizing  process to improve its resistance to corrosion.

This process typically involves dipping the finished wire product into a bath of heated zinc compound to form a scratch and corrosion resistant coating across the entire surface of the wire.

 

APPLICATION:

The galvanized steel wire strand is used for overhead ground lines or electrical power transmission lines. Stay wire or guy wire strands are produced for use with poles, towers, or any other form of guying.

 Its low cost and ease of production makes galvanized steel wire ideal for mass produced corrosion resistant wire products,which is indispensable in industrial, agricultural.


CONSTRUCTION:

Concentrically stranded Galvanized steel wire strand available in class "A", "B" and "C" galvanizing, "A" being the least heavy and "C" being the most heavy. Manufactured without welds per ASTM A-363 or with welds per ASTM A-475. Strands are formed to remain substantially in place when severed.


Zinc-coated grade of steel strand wire /guy wire : Class A ,Class B and class C.


STANDARDS:

ASTM A475, BS183:1972.
