Steel reinforcing mesh is a kind of reinforced products ,respectively by lateral and longitudinal reinforcement spacing must be arranged and mutual at right angles, all with strong resistance pressure are crossing the steel welding together piece. Steel reinforcing mesh is a new, efficient, high-quality steel reinforced concrete structures of application in industrial and civil building roof, the floor, walls, floors, concrete road and bridge deck pavement, airport runway, tunnel lining, concrete pipe, pile, etc. With welding steel reinforced concrete of the technical performance and advantages: 1, could be massively reduce reinforced installation hours, less than 50% labor locally nets when - 70%. 2, with a dense network of reinforcement spacing, welding dyc and longitudinal reinforcement grid formation structure reinforced joint up bond anchorage action to prevent concrete crack generation and development, pavement, floor, floor configuration welding nets can reduce the concrete surface cracking 75%. 3, especially suitable for large area concrete engineering, the holes of the welding nets very neat, far above manual binding nets, mesh stiffness big, good flexibility, reinforced concrete was not pour out local bend, deformation and produce sliding phenomenon, concrete cover depth easy control, even, obviously improved reinforced concrete engineering quality. 4, welding nets has good overall economic efficiency, welding nets reinforced design strength reinforced 50% higher than the level I smooth steel welding (network) ~ 70% (ribbed steel welding nets), consider some structural requirements still can save 30%, combined with steel under 12mm scattered teams in diameter is about cost of reinforced processing 10% ~ 15%. Considering (compared with level I steel reinforcement engineering cost) can reduce around 10%.
