Welded wire mesh for cold-rolled ribbed reinforcement The machine arranges the longitudinal and transverse cold-rolled ribbed steel bars of the same or different diameters at vertical intervals, and all the crossing points are rebar meshes welded together by resistance spot welding. As a new building material, cold-rolled ribbed steel bars and welded steel meshes are listed by the Ministry of Construction as one of the 10 new technologies that are important to promote the application of building materials and the construction industry. This technology will replace the traditional manual banding of steel bars in building construction, has the superior performance of improving construction speed, ensuring project quality, reducing material consumption, and can promote the industrialization level of building material production. Reinforced welded wire mesh makes the reinforcement engineering take the factory road, which is the trend of the world's architectural development. It is not only a new type, high-performance structural material, but also a highly efficient construction technology. It is the fundamental transformation of rebar engineering from manual operation to factory and commercialization. Developed in the world * has been widely adopted, and China has developed rapidly in recent years.
