Detailed explanation of rebar welding mesh size ‌

‌ Steel bar diameter ‌ : usually between 4mm-14mm, the specific diameter such as 5mm, 6mm, 8mm, 10mm, etc., can be selected according to engineering requirements. When the vertical and horizontal steel bars of the welding network are single steel bars, the diameter of the thinner steel bars should not be less than 0.6 times the diameter of the thicker steel bars.

‌ Hole size ‌ : The hole size can be customized according to the needs of the project, the common ones are 100mm x 100mm, 150mm x 150mm, 200mm x 200mm, etc., and there are also 300mm or 400mm spacing.

Mesh slice dimension : Taking into account the transport conditions, the length is generally not more than 12m, width not more than 3.4m. However, in actual engineering, it can be customized according to specific needs. For example, the width of some nets can reach 1m to 2m, and the length can reach 20m or 30m.

The advantages of rebar welding mesh

1.Improve project quality

With a dense bar spacing, the longitudinal and transverse bars of the welded mesh form a network structure to bond and anchor together, which is conducive to preventing the generation and development of concrete cracks, and the configuration of welding mesh on the road, floor and floor can reduce the crack of the concrete surface by about 75%.

Especially suitable for large-scale concrete projects, the mesh size of the welded mesh is very regular, far beyond the manual binding net, the mesh stiffness is large, good elasticity, the reinforcement is not easy to local bending, deformation and slip phenomenon when pouring concrete, the thickness of the concrete protective layer is easy to control, uniform, significantly improve the quality of reinforced concrete engineering.

2.Cost saving

The design strength of the welded steel bar is 50% higher than that of the I-grade steel bar (smooth steel bar welding mesh) -70% (ribbed steel bar welding mesh), considering some structural requirements can still save about 30% of the steel bar, plus the processing cost of loose steel bar with a diameter of 12mm is about 10%-15% of the material cost. Comprehensive consideration (compared with grade I steel) can reduce the steel engineering cost of about 10%.

3.Increase construction speed

A large number of construction practices at home and abroad show that the use of welding mesh greatly reduces the on-site installation hours and saves the bar processing site. In the case of the same amount of reinforcement, the 1000kg welding net takes about 4 hours according to the single-layer laying, such as the double-layer net takes more than 6 hours, and the manual binding takes 22 hours, which can save about 50%-70% labor compared with the manual binding time.
