Steel mesh sheet

In modern construction engineering, steel mesh, as an important building material, is playing an increasingly critical role. It provides solid and reliable support for various building structures with unique construction and excellent performance, becoming one of the core elements to ensure building quality and safety. ​
1, Construction and characteristics of steel mesh
Steel mesh is a mesh structure formed by intersecting longitudinal and transverse steel bars, connected by welding or binding. This orderly arrangement endows it with many significant characteristics. Firstly, it has strong overall integrity. Compared with the traditional arrangement of single steel bars, steel mesh can more evenly distribute stress in concrete, effectively enhancing the bearing capacity and seismic performance of concrete structures. For example, in buildings in earthquake prone areas, walls and floors reinforced with steel mesh can better resist the impact of seismic forces and reduce the risk of structural damage. ​
Secondly, steel mesh has high strength and stability. The high-strength characteristics of steel bars themselves, combined with reasonable grid design, make them perform excellently under various loads. Whether it is static loads such as the weight of the building itself, or dynamic loads such as wind, vehicle vibrations, etc., steel mesh can evenly transmit the force, maintain the stability of the structure, and greatly improve the safety and durability of the building. ​
In addition, the construction convenience of steel mesh is also a prominent advantage. At the construction site, prefabricated steel mesh can be directly lifted to the designated location for installation, reducing the workload and time of on-site steel binding, improving construction efficiency, and also reducing labor costs. This fast installation feature can significantly shorten the construction period and accelerate the project progress for large-scale construction projects. ​
2, Manufacturing process of steel mesh
The manufacturing process of steel mesh directly affects its quality and performance. At present, the common production methods mainly include welding and binding. ​
The welded steel mesh adopts professional automated welding equipment to firmly connect the longitudinal and transverse steel bars through resistance spot welding. This welding process can ensure the strength and quality of the welding points, making the integrity of the steel mesh stronger. During the welding process, precise control of welding current, time, pressure and other parameters is crucial to ensure that each welding point can meet the specified welding strength standards and avoid defects such as virtual welding and missed welding. Automated welding equipment not only improves production efficiency, but also ensures consistency and stability in product quality, making it suitable for large-scale production. ​
Binding steel mesh is to use iron wire to tie and fix the longitudinal and transverse steel bars at the intersection. Although this method is relatively traditional, it still has applications in some small projects or special structural parts. The binding process requires workers to have certain skills and experience to ensure firm binding and even spacing. Compared with welding steel mesh, the overall integrity of tying steel mesh is slightly inferior. However, in some situations where welding construction is limited, such as in small spaces where welding equipment cannot be used, the tying method is flexible and feasible. ​
3, Application of steel mesh in construction engineering
Building foundation: In the construction of building foundations, steel mesh is widely used in raft foundations, strip foundations, etc. It can enhance the bearing capacity of the foundation and prevent uneven settlement caused by the huge load transmitted from the upper structure. For example, in the raft foundation of large commercial buildings, laying multiple layers of steel mesh can effectively disperse the weight of the building, ensure the stability of the foundation, and lay a solid foundation for the safety of the entire building. ​
Wall structure: In wall construction, steel mesh can be used for reinforcing masonry structures and reinforcing concrete walls. In masonry structures, placing steel mesh in the mortar joints can enhance the overall integrity and seismic performance of the wall, and improve its ability to resist horizontal forces. For concrete walls, steel mesh serves as the main load-bearing steel bar, working together with concrete to withstand various loads and ensure the strength and stability of the wall. In the shear wall structure of high-rise buildings, the reasonable configuration of steel mesh plays a key role in improving the shear and bending resistance of the wall. ​
Floor slabs and roofs: Steel mesh is equally indispensable in the structure of floor slabs and roofs. As the load-bearing reinforcement of the floor and roof, it can withstand the live and dead loads transmitted from the floor and roof, and transfer the loads to vertical load-bearing components such as beams and columns. At the same time, the steel mesh can effectively prevent cracks in the floor and roof due to temperature changes, concrete shrinkage, and other reasons, improving the waterproof performance and durability of the structure. For example, in the roof construction of industrial plants, the combination of steel mesh and lightweight insulation materials can ensure the structural strength of the roof and achieve good insulation and thermal insulation effects. ​
Road and Bridge Engineering: Steel mesh also has important applications in road and bridge engineering. In road surface construction, steel mesh can be laid on the base of cement concrete pavement to enhance the crack resistance and bearing capacity of the pavement, and extend the service life of the pavement. In bridge engineering, steel mesh is used for bridge deck paving, reinforcement of piers and abutments, and other parts of the bridge. For example, in bridge deck pavement, steel mesh can effectively prevent cracks from appearing on the bridge deck, improve the flatness and driving comfort of the bridge deck, and enhance the connection performance between the bridge deck and the main structure of the bridge, ensuring the overall stability of the bridge.
