Welded steel mesh is mainly used in urban construction.

Urban construction-specific welded steel mesh is a mesh in which longitudinal and transverse steel bars are arranged at specific intervals and perpendicular to each other, with all intersections welded together. It is classified into two types according to the grade, diameter, length, and spacing of the steel bars: standard welded steel mesh and custom welded steel mesh.

The construction process for building-specific welded steel mesh is as follows: Mark the steel bar position lines on the formwork → Lay the lower layer of mesh → Pre-embedded sections for civil engineering and water/electricity systems → Install the upper layer of mesh using support supports → Erect the support walkway → Acceptance of concealed works → Re-inspection and maintenance during concrete pouring.

The difficulties of constructing building-specific welded steel mesh compared to ordinary steel bar binding include:

1. For irregularly shaped edges of buildings with complex structures, straight strips need to be bound or cut on-site.

2. For reserved openings, pipe shafts, ventilation shafts, etc., the welded steel mesh needs to be cut, adjusted, and reinforced on-site, which is difficult.

3. Using HRB400 hot-rolled ribbed steel mesh, which is a double-layered, bidirectional welded mesh, the diameter and spacing of the bottom and top mesh steel bars are different, posing significant construction challenges.

Applications of Welded Reinforcing Mesh for Construction: Welded reinforcing mesh is widely recognized domestically and internationally as a new, efficient, and high-quality steel material for reinforced concrete structures. It is extensively used in industrial and civil buildings for floor slabs, roofs, walls, floors, concrete pavements, bridge decks, airport runways, tunnel linings, concrete pipes, and piles.

Features of Welded Reinforcing Mesh for Construction:

1. Welded reinforcing mesh saves materials and shortens construction time.

2. After forming, the welded reinforcing mesh is less prone to deformation, strengthening its bond with concrete, reducing cracking, increasing overall concrete strength, and ensuring construction quality.

3. Welded reinforcing mesh creates a uniform load distribution on the concrete structure, improving the load-bearing capacity and shear resistance of components.

4. Welded reinforcing mesh overcomes the problems of inconsistent rebar spacing and missed ties caused by manual binding.

5. Welded reinforcing mesh technology reduces labor input, speeds up construction, reduces noise pollution during straightening operations, and promotes civilized construction and environmental protection.

6. It saves steel and improves economic efficiency.

Advantages of Reinforcing Mesh: Reinforcing mesh is manufactured in a factory under strict quality control using a fully automated, intelligent production line. Mesh size, rebar specifications, and quality are all strictly controlled. The longitudinal and transverse bars of the reinforcing mesh form a mesh structure, resulting in excellent bonding and anchoring with concrete. This ensures even load distribution and significantly improves the seismic crack resistance of reinforced concrete structures. Using welded reinforcing mesh in road paving reduces cracking by more than 75% compared to manually tying mesh. Using reinforcing mesh speeds up construction. Simply lay the mesh as required, and concrete can be poured, eliminating the need for on-site rebar cutting, placement, and tying. This can save 50%-70% of labor time, greatly accelerating construction progress and shortening the construction cycle. Reinforcing mesh has a wide range of applications.
