The opposite side aperture of each grid of the US grid is generally 6.5cm-14cm. The thickness of the wire used is generally from 3.5mm-6mm. The wire material is generally Q235 low-carbon iron wire. The iron wire is welded into embossed black mesh. The overall dimensions of the mesh are generally 1.5 meters by 4 meters, 2 meters by 4 meters, and 2 meters by 3 meters.
General surface treatment is cold (electric) galvanizing. There are also hot-dip galvanizing, dipping, spraying. But overall, ninety-nine percent are cold (electric) galvanized. There are several points to note about the U.S. grid
The smaller the mesh size of the JM grid, the finer the warp is required, and the larger the mesh, the thicker the warp is required. For example, a mesh diameter of 6.5cm requires an iron diameter of 3.5mm-4mm. It will break if it is thinned again, and it is too heavy for the workers to bear.
The overall size of the Rimage grid does not exceed 2 meters. The length is generally not more than 4m. More than 2 meters, one is laborious, and the other is poor galvanization. The length can also reach 6 meters, but it will not exceed 6 meters. Generally more than 4 meters after the price will increase significantly.
3. Whether the solder joint is firmly welded.
Mei grid welding joints are generally relatively strong, but if the worker is a novice and the technology of adjusting the machine is not high, the situation of welding joints will appear. Once this situation occurs, it will inevitably bring major losses to customers and factories.
4. Galvanizing process
Galvanization is also a problem-prone part of the Grid. Many workers are irresponsible. The boss is a little inattentive, and the worker is likely to shorten the galvanization time quickly, resulting in a situation where zinc is not available. As a result, factories and distributors can also suffer significant losses.
