Advantages of Welded Steel Mesh

Welded steel mesh is a kind of construction mesh that uses a special welding machine to weld longitudinal and transverse steel bars of the same or different diameters by resistance spot welding (low voltage, high current, and short welding touch time).

The longitudinal steel bars and the transverse steel bars of the welded steel mesh are placed at a certain distance and at right angles to each other, and all the intersection points are welded together by resistance spot welding. With a denser steel bar spacing, the longitudinal bars and transverse bars of the welded mesh form a mesh structure that acts as a bond and anchorage, which is beneficial to prevent the occurrence and development of concrete cracks. Crack about 75%.

Useful of reinforcing welded mesh:

Welded steel mesh is considered to be a new type of high-efficiency and high-quality steel for reinforced concrete structures and is widely used. Welded steel mesh is used in beams and columns, floors, roofs, walls, floors, concrete pavements, bridge decks, airport runways, tunnel linings, concrete pipes, and piles of industrial and civil houses.

Advantages of welded steel mesh:

1.     Compared with the traditional technique of binding steel bars, the welded steel mesh has the advantages of high rigidity, good elasticity and uniform distance.

2.     When pouring concrete, the steel bar is not easy to be partially stepped on, and the thickness of the concrete protective layer is easy to control and uniform. In the bridge deck pavement, the qualified rate of the measured welded mesh protective layer is above 95%.

3.     The selection of welded mesh greatly reduces the on-site installation time and saves the steel bar processing site. In the case of the same amount of reinforcement, the use of steel mesh can save about 50% to 70% of the time compared to manual binding.

4.     The intersection of artificial wire binding is easy to slide, and the bonding force between steel bar and concrete is weak, which is prone to cracks, while the welded joints of welded mesh can not only withstand pressure, but also shear force.

5.     Longitudinal and horizontal steel bars form a mesh structure to play a bonding and anchoring effect. When the welded mesh steel bar is selected with a smaller diameter and a denser distance, because of the increase of welding points per unit area, it is more conducive to enhancing the crack resistance of concrete, which can Cut cracks by more than 75%.

6.     The selection of welded mesh saves a lot of on-site binding labor and construction site, enables civilized construction, and significantly improves the quality of steel reinforcement projects. Because the welded mesh is prefabricated in the factory in advance, there is no need for reprocessing on site, and there is no steel waste head, because the shortened The construction period is reduced, and the cost of hoisting machinery and so on is cut.

7.     Compared with the use of I-grade steel bars, the planned strength of ribbed steel mesh is about 70% higher than that of I-grade steel bars. After considering some structural requirements, it can still save more than 25% of steel.

8.     Welded mesh has good comprehensive economic benefits. The design strength of welded mesh is 50% higher than that of grade I steel (smooth steel welded mesh) ~ 70% (ribbed steel welded mesh), and it can still be used after considering some structural requirements.
