Welded steel mesh for reinforced concrete is a welded steel mesh for reinforced concrete with reinforced concrete and cold rolled ribbed steel or cold rolled round steel. It is a good and efficient material for concrete distribution. Its emergence is of great significance to improve building con-
struction efficiency, structural quality and safety reliability, and to change traditional building construction methods.

Steel bar grating costs less time and labor in work. It saves about 50 to 70 percent work time compared with common binding wire mesh. The use of bar grating can also strengthen the concrete parts to reduce surface breaking ratio. Welded bar grating for reinforcement is especially suitable for big area concrete engineering. Using of welded bar reinforcement can save about 10 percent of the total cost of the project.
