Galvanized Steel Wire for Messengers

Construction

1. Unless otherwise specified,strand shall have a left lay.All wires shall be stranded with uniform tension.

2. Stranding shall be sufficiently close to ensure no appreciable reduction in diameter when stressed to 10% 

of the specified strength.

3. Stranding wire:1*3,1*7,1*19,1*37.

4. All wires in the strand shall lie naturally in their true positions in the completed strand and,when the strand is cut,

the ends shall remain in positions or be readily replaced by hand and then remain in position.This may be 

accomplished by any means or process,such as preforming,post forming or form-setting.

5. The zinc-coated wire shall be free fo imperfections not consistent with good commercial practice.

The zinc-coating shall be continuous and of reasonably uniform thickness.
