80x100mm High strength double twist steel wire mesh used as
Rockfall protection netting,consists of galfan coated steel wire or pvc coated hot dipped galvanized steel wire.
The steel wire used in the manufacture of
double twist steel wire mesh is heavily galvanized with Galfan, a Zn-5%Al-mischmetal alloy coating low carbon steel wire.
Due to the characteristics of the double twist, the
steel wire mesh can withstand the force of falling rocks without unraveling in the event of wire breakage.
