The difference between cold-rolled ribbed steel bar welded mesh and hot-rolled ribbed steel bar welded mesh

According to raw materials, welded steel mesh can be divided into: cold-rolled ribbed steel welded mesh, cold-drawn round steel welded mesh, hot-rolled ribbed steel welded mesh, among which cold-rolled ribbed steel welded mesh is widely used. According to the grade, diameter, length and spacing of steel bars, welded steel mesh can be divided into two types: shaped steel welded mesh and customized steel welded mesh.

Advantage:

Significantly increase the construction speed, enhance the crack resistance of concrete, and have good comprehensive economic benefits

1. Engineering quality:

The welded steel mesh is manufactured by a fully automatic and intelligent production line under the strict quality control of the factory. Mesh size, bar specification and quality are strictly controlled. It avoids the omission of the artificial side netting. The side part is strong. Mistakes and cutting corners happen.

The mesh has high rigidity, good elasticity, uniform and accurate spacing, and high welding point strength. Thus greatly improving the quality of the project. the

2. Improve the anti-seismic and anti-crack performance:

The longitudinal bars and transverse bars of the welded steel mesh form a network structure, so it has good bonding and anchoring properties with concrete, and the load it bears is evenly spread and distributed, which significantly improves the anti-seismic cracking performance of reinforced concrete structures. According to actual tests, road paving with welded steel mesh can reduce cracks by more than 75% compared with artificial mesh. the

3. Save steel consumption:

The design strength value of the widely used round steel bar is 210N/mm (pingfang), while the design strength of the welded steel mesh is 360N/mm (pingfang). According to the principle of equal strength replacement and considering comprehensive factors, the use of welded steel mesh can save More than 30% of the steel bar usage. And the steel mesh needs to be processed after being transported to the construction site, so there is no loss.
