1.reinforcing steel mesh ground slabs made of low carbon steel wire rod, which undergo a cold-rolling and straightening process and arranged vertically in proper spacing in the welding machine at the line wires and cross wires, joint together by mean of electric resistance spot-welding, also directly welded with hot rolled wire rods
The reinforcing mesh has following merits:
Great hardness, good elasticity, uniformity spacing high welding strength, hard to deform by trample
