Welded Steel Nets are used after a cold-rolled low-carbon wire rod, straightening after welding equipment will be vertically and horizontally to the Net reinforced separately with a certain pitch, all cross-points together with resistance spot welding (also can be directly hot-rolled wire rod thread welding) formed steel mesh. Net use of reinforced welded steel banding compared with the ordinary has significant advantages: one, the protection of reinforced the quality of the project: Large mesh stiffness, good elasticity, spaced evenly, welding Net high and difficult to stampede deformation, protective layer of concrete and easily manipulated. 2, improve construction efficiency: saving more than 50% of labor, saving 50-70% of working hours. 3, enhance concrete crack
