The widespread and rapid popularization and application of cold-drawn ribbed steel bars and hot-rolled grade III steel bars in my country provides a material basis for the development of welded mesh. The official implementation of mesh product standards and operating procedures has played a positive role in improving product quality and promoting application. It is the trend of the steel industry to develop the support mesh road in the construction of steel reinforcement. This new reinforcement method is especially suitable for large-area concrete projects. Mine wire mesh supplier.

It is mainly used as a false roof and guard for the layered mining of thick coal seams in coal mines, and can also be used as a supporting material for various roadways such as bolt roadway, support roadway, bolt-and-shot roadway, etc. When used for false roofs, it must be used in combination with more than two layers. In addition, it can also be used as an anchoring and reinforcing material for other mine roadway engineering, slope protection engineering, underground civil engineering and traffic road engineering. Mine wire mesh supplier.

The stainless steel support mesh used for the ceiling is also different, with large holes, small holes, useful thick plates, useful thin plates, some thicker and some thinner, etc. The commonly used stainless steel supporting meshes have apertures of 15*25mm, 15*30mm, 30*50mm, 40*80mm, 50*100mm, etc. The commonly used plate thickness is 1.2mm-2.5mm, and the thicker plate should be selected. The state is produced, and after the weight is added, it is not conducive to the development of the ceiling operation.

The shear strength of the reinforcement supporting mesh mesh points should be in accordance with the following rules: F > 150, element factor 150 N/mm2 Type: F---Measured shear force (N)---tensile reinforcement area (square mm), the less force should be set in the direction of the force to force the lap mesh of the rebar. Mine wire mesh supplier.
