6*6 concrete hot dipped galvanized reinforcing mesh

The minimum diameter and maximum spacing of reinforcing mesh for reinforced concrete pavement shall comply with current industry standards. When cold-rolled ribbed steel bars are used, the steel bar diameter shall not be less than 8mm, the longitudinal steel bar spacing shall not be greater than 200mm, and the transverse steel bar spacing shall not be greater than 300mm. The vertical and horizontal steel bars of the welded mesh should have the same diameter, and the thickness of the protective layer of the steel bars should not be less than 50mm. The welded mesh for reinforced concrete pavement reinforcement can be implemented in accordance with the relevant regulations for welded mesh for reinforced concrete pavement.

Mainly used in bridge deck pavement of municipal bridges and highway bridges, renovation of old bridge decks, anti-cracking of bridge piers, etc. The quality acceptance of thousands of bridge applications in China shows that the use of welded mesh can significantly improve the quality of the pavement layer of the bridge deck, the pass rate of the thickness of the protective layer is over 97%, the flatness of the bridge deck is improved, the bridge deck is almost free of cracks, and the pavement speed is increased More than 50%, reducing the cost of bridge deck pavement by about 10%.

According to national regulations, the ribbed reinforcing mesh should be installed in shotcrete, which is conducive to improving the shear and bending strength of shotcrete, improving the punching resistance and bending resistance of concrete, improving the integrity of shotcrete, and reducing the risk of shotcrete.
