Construction mesh has great competitive advantages in the construction industry. In summary, the main points are as follows:

1. Construction mesh saves materials. Due to the high strength of construction mesh, nearly 30% of steel can be saved compared with ordinary first-grade steel in engineering applications. This is particularly important in times of energy shortage.

2. The building mesh is easy to construct and of high quality. The welded steel mesh is produced in the factory according to the design drawings and installed on site. Therefore, compared with traditional on-site manual tying, it not only improves the quality of the project, but also speeds up the construction progress and shortens the construction period.

3. Support of industry standards related to construction mesh. The production and construction of welded steel mesh are strictly based on the "Technical Regulations for Concrete Structures of Welded Steel Mesh", which guarantees the production quality of welded steel mesh. This regulation was edited by the Academy of Construction Sciences and approved by the Ministry of Construction. Technical demonstration by the scientific research department is an important prerequisite for the application of welded mesh.

4. The efforts of many wire mesh manufacturers and the innovation of construction concepts by engineering and technical personnel are the direct driving force for the promotion and use of construction mesh.

5. It can greatly reduce the installation time of steel bars, which is helpful to prevent the occurrence and development of concrete cracks and reduce concrete surface cracks. The mesh size of the welded mesh is regular and has good elasticity. When pouring concrete, the steel bars are not easy to bend, deform and slip locally. Phenomenon, it can reduce the steel project cost by about 10%.

In the construction mesh, due to the high strength, large shrinkage, and insufficient flexibility and deformation of the cement mortar, it directly acts on the outside of the insulation layer and has poor weather resistance, causing cracks. In order to solve this problem, special anti-crack mortar is used and supplemented by reasonable reinforcement mesh - steel wire mesh is added to the cement anti-crack mortar. The steel wire mesh should be anti-corrosion 12.7×12.7mm hot-dip galvanized steel wire 12.7×welded mesh. There are 80 mm long expansion bolts on the galvanized steel mesh in the form of plum blossom piles (50 cm apart) and riveted into the exterior wall. Then the welded mesh is made with an impermeable and crack-resistant mortar, and then the face bricks are constructed.
