Steel mesh can play the role of steel bars, effectively reducing cracks and depressions on the ground, and is widely used in the hardening of highways and factory workshops. Mainly suitable for large-area concrete projects, the mesh size of the steel mesh is very regular, much larger than the mesh size of the manual binding net. The steel mesh has great rigidity and good elasticity. When pouring concrete, the steel bars are not easy to bend, deform and slide. In this case, the thickness of the concrete cover is easy to control and uniform, which greatly improves the construction quality of reinforced concrete.
