Coal mine network USES:

Coal mine roadway network security protection, coal mine special bilateral weave, connection and firm, not variant, strong protection, easy construction, safety performance is high, was our country coal mine safety department as the coal mine roadway protection private networks.
Steel bar welded mesh has been widely used in architecture, except for prefabricated reinforced concrete is made more is used in the cast-in-place concrete structures, the construction industry: Multi-storey and high-rise industrial and civil building construction (foundation, floor, floor, roof, wall, etc. ); Transportation: Highway, highway concrete pavement and bridge deck pavement layer of soft ground, ground surface crack, toll plaza concrete piers, concrete ground, railway station, station square and cargo airport runway, freight yard and the square concrete ground, tunnel lining, terminals, ports, etc.; Municipal construction: Elevated overpass ground surface pavement, square concrete, concrete pipe, fence, slope protection, etc.; Hydraulic power coal, water conservancy facilities, electric power dam foundation, fence, etc.; Other: Flood control facilities collapse and slope reinforcement and protection, husbandry, animal husbandry, etc.

Reinforced concrete with welded steel fabric in the technical performance and advantages:
1, reinforcement fabric reinforced installation can dramatically reduce working hours, labor 50% - 50% less than binding network.
2, steel mesh at a relatively dense bar spacing, the welding net of longitudinal reinforcement and transverse reinforcement form reticular structure joint bond anchorage effect, is beneficial to prevent the cracks of concrete and the development, road surface, floor, floor configuration welding net can reduce concrete surface crack is about 75%.
3, steel mesh especially suitable for large area concrete engineering, welding net mesh size is very neat, far beyond the manual binding network, mesh stiffness, good elasticity, pouring concrete reinforcing steel bar is not easy to local bending, deformation and sliding phenomenon, thickness of concrete cover is easy to control, uniform, significantly improve the quality of reinforced concrete engineering.
4, reinforcing mesh welding wire mesh has good comprehensive economic benefits, the design of the welded mesh steel bar intensity is higher than class I reinforced by 50% ~ 70% (smooth steel welding net) (ribbed steel bar welded mesh), still can save steel after considering some structure to ask about 30%, below with 12 mm diameter scattered the reinforced processing fee of about 10% to 10% of the cost of raw materials. Considering (compared with grade I reinforced) can decrease the reinforcement engineering cost about 10%.
