Steel mesh steel mesh is reinforced by longitudinal and transverse cross made of welded mesh or by banding. Construction is one of the "2005 10 construction focused on the promotion of new technology" content. Steel mesh press materials can be divided into: cold-rolled ribbed steel mesh, drawing light round steel mesh, hot-rolled ribbed steel mesh, including cold-rolled ribbed steel mesh the most widely used. Reinforced by steel mesh grade, diameter, length and pitch into stereotypes and customized steel mesh steel mesh two kinds. Welded steel purposes: domestic and recognized as a new, efficient, high-quality steel and reinforced concrete structures widely used in industrial and civil buildings of the floor, roof, walls, floors, concrete pavement, bridge deck, airport runway, tunnel lining, concrete pipes, piles, culvert, dock floor, precast and other fields. Technical characteristics and advantages of the steel mesh steel mesh: 1, can significantly reduce the steel installation work, while more than 50% less labor lashing net --70%. 2, denser reinforcement spacing, longitudinal welded steel bars and horizontal bars from bonded together to form a network anchor role in helping to prevent the emergence and development of cracks in concrete, pavement, floor, floor welded mesh configuration can reduce concrete surface cracks around 75%. 3, especially for large-scale concrete works, welded mesh size is very regular, far more than in the manual banding nets, mesh stiffness, elasticity, reinforced concrete is not easy when watering local bending deformation and slip phenomenon, concrete cover thickness is easy to control, even, significantly improved the quality of reinforced concrete works. 4, welded mesh has good overall economic efficiency, the design strength of welded steel than I 50% of high-grade steel (smooth steel welded mesh) to 70% (ribbed steel welded mesh), even after considering some of the structural requirements save about 30% of steel, plus 12mm diameter steel processing fees following branches scattered about material costs 10% to 15%. Considering (compared with the I grade steel) can reduce the reinforcement project cost about 10%. 5, take the welded steel construction road is the trend of the world steel industry. 6, steel mesh reinforcement in the form of this new, especially for large-scale concrete works. 7, our ribbed steel cold drawn, hot rolled steel grade III widespread and rapid application to provide a good foundation for welded mesh material development. Welded mesh product standards and procedures for the use of official purposes, to improve product quality, accelerate application has played a positive role. 8, China's huge potential market demand for steel mesh. 9, steel mesh aesthetically pleasing. 10, China is the world of steel big country. 11, steel mesh in the country's development has had the soft and hard conditions. Welded steel mesh network using a dedicated GWC welding machines, welding procedures by computer control production, welded mesh uniform, good quality welding, mechanical properties of steel almost unchanged before and after welding. Steel mesh should adopt CRB550 grade cold-rolled ribbed steel or of HRB400 hot rolled ribbed steel production, may also CPB550 grade level cold drawn smooth steel production. Steel mesh
