Hot Dipped Galvanised Iron Wire
Hot Dipped Galvanised Iron Wire ( simplified as HDG wire) with heavy zinc plating is used mainly for wire fences and wire meshes manufacture. Iron steel wire of thinner wire diameter requires less zn coating than thicker wires in the hot dip galvanizing process. The zinc coating quantity per square meter of the iron wire normally increases with the wire diameter to guarantee the galvanizing wire quality.
HDG Wire Quality
DIN 17140
BS1442/BS443
EN 10244-1, 10244-2, 10257-1
HDG Wire Properties
Common tensile strength range: 340 - 500 N/mm²
Wrapping test requirement:
Wrapping test around a mandrel for one complete turn. The mandrel shall have a diameter of 4d (d nominal wire diameter)- wires shall not break.
Elongation: 10% for all size, with exception of 0.87mm wire which should have minimum elongation at break of 7.5%.
Max resistivity: 138 Ohm.mm2/km at 20 0C.
