Rebar mesh can act as steel bars, effectively reducing cracks and depressions on the ground, and is widely used for hardening on 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 hand-tied mesh. The steel mesh has high 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 protective layer is easy to control and uniform, thereby greatly improving the construction quality of reinforced concrete.
