The production technology of Dalian heavy steel mesh has special requirements

After forging, the physical properties of Dalian heavy steel plate mesh will also change, which may affect its welding process. The carbon content of steel is an important factor affecting the properties of steel mesh. Here we explain the forging performance of metal steel grating. The products will be pressed and welded by the machine during manufacturing. In the process of forging, due to heating, forging and cooling, the structure and properties of materials will change greatly. This will improve the chemical properties of metal materials, but at the same time, it will produce great internal stress.

Steel plate mesh is a steel product made by cross welding of bearing flat steel and cross bar. The bearing flat steel is used to bear gravity. The cross bar has the effect of fixing the bearing flat steel. The two ends of the bearing flat steel of the steel plate mesh must be placed on the bearing beam to have the effect of bearing. Therefore, the direction parallel to the bearing flat steel is the force bearing direction of the steel plate mesh.

Generally, high-quality carbon structural steel or stainless steel is used, which requires high strength and good corrosion resistance. Its chemical composition and mechanical properties shall comply with Q235A of GB70088 or 0Crl8Ni9 of GBl22092 respectively. Each bearing flat steel and wrapped flat steel shall be double-sided fillet welding and the weld shall not be less than 3MM; The connection between each bearing flat steel and the twist rod is fully welded; After the semi-finished black parts are manufactured, the spatter, welding slag, burr must be removed, the four corners must be polished without sharp edges, and the whole board must be leveled.

The surface treatment of hot-dip galvanized steel mesh can be hot-dip galvanized to prevent oxidation. It can also be made of stainless steel, sprayed with plastic, and cold galvanized. It has the characteristics of good load bearing, does not need too much material support, and bears the same gravity. Compared with other specifications of hot-dip galvanized steel mesh, it is not easy to deform, resistant to corrosion, impact, and has a long service life.

Stemming width of steel mesh: Stemming width of steel mesh is the width of each mesh edge. Stemming width is generally greater than or equal to the plate thickness. Stemming width determines the hardness of steel mesh and the weight of steel mesh.

Stemming width and plate thickness of steel mesh: plate thickness refers to the thickness of raw material steel plate of steel mesh, which is the specification required for customized steel mesh.

Mesh of steel plate mesh: the mesh shape is generally rhombic, some are hexagonal honeycomb and rectangular, and the mesh size is generally the middle to middle distance between stems.

Wire mesh thickness: wire mesh thickness refers to the thickness of the wire mesh after stamping. Before customizing the wire mesh, the manufacturer is generally provided with the thickness of the required plate, but not the thickness of the wire mesh. The wire mesh thickness is affected by many factors, such as the thickness of the plate and the width of the stem.
