Steel mesh, also known as: welded steel mesh, steel welded mesh, steel welded mesh, welded steel mesh, steel mesh and so on. Is the vertical and horizontal steel reinforcement were arranged a certain distance and at right angles to each other, all cross-points are welded mesh together. About steel mesh steel mesh reinforced by vertical and horizontal cross banding or welding is made by the network. Ministry of Construction, "2005 focused on promoting construction of 10 new technology application," one of the elements. The theoretical weight of steel mesh formula: RC Networks, weight (KG) = length of steel mesh reinforcement used (M) * Wire Diameter (MM) * Wire Diameter (MM) * 0.00617 mesh reinforcement applications in industrial and civilian housing beam floor, roof, walls, concrete pavement, pavement, airport runway, tunnel lining, box culvert, the terminal floor, precast and other fields. 1, welded steel construction of the road is the world take the steel industry development trend. 2, steel mesh reinforcement of this new form, especially for large-scale concrete works. 3, of drawing ribbed steel bars, hot rolled steel grade III broad, rapid application development for the welded material to provide a good foundation. Welded mesh product standards and the use of order into effect, for improving product quality, accelerate the popularization and application to play a positive role. 4, China's market demand for steel mesh potential. 5, steel mesh aesthetically pleasing. 6, China is the world's steel, power. 7, the development of steel mesh in the country has had the soft and hard conditions. Welding technique using a dedicated GWC Welding Machine, welding procedure by the computer control production, welded mesh uniform, good welding quality, the mechanical properties of welded steel before and after little change. Steel mesh should adopt CRB550 class cold rolled ribbed bar or HRB400 grade hot-rolled ribbed steel bar production, but also can be cold drawn round steel CPB550 grade-level production. Classified by raw materials, steel mesh can be divided into: cold-rolled ribbed steel net, drawing a round of light steel mesh, hot-rolled ribbed steel mesh, cold rolled ribbed steel mesh of which the most widely used. Steel mesh steel grades according to diameter, length and pitch into shape, and custom steel mesh steel mesh the two. Project benefits significantly improve the quality of steel reinforced concrete construction speed significantly improved crack resistance with good overall economic efficiency
