Many reasons can lead to the deformation of the steel grating, such as the implementation of the surface hot galvanizing and transportation process, which makes the customer notice that there are many entrances and exits in the appearance of the steel grating and the size of the initial drawing when receiving the product. Cause disputes between customers and manufacturers. Here we look at the deformation of steel grating and take measures to prevent it
Deformation of hot-dip galvanized steel grating: when the steel grating is treated with hot-dip galvanized steel plate, the steel grating will change due to high temperature. Shape phenomenon: if the steel grating has strong internal stress in the future welding, it will have large deformation. Internal stress of steel grating bottom plate. If the steel grating is welded, the flat steel is not straightened, but when the flat steel is directly welded on the mold, it looks straight. In fact, the steel grating produces relatively strong internal stress.
Add a strong external force (such as high temperature, slapping, squeezing), and the internal stress will be exposed, and the appearance of the steel grating will become a horizontal bow. Although they were prevented from being hit, squeezed and impacted, steel mesh packages were still transported. How to prevent the deformation of hot-dip galvanized steel grating: first weld the steel grating and then straighten the flat steel after the process welding. When the flat steel shows an arc bending pattern, the flat steel will not be straightened during welding, but will be straightened. After welding on the mold, it looks straight. In fact, the steel grating has strong internal stress. Before pickling and hot-dip galvanizing, the steel grating is subjected to internal stress. If the internal pressure appears, the appearance will change.
For horizontal shape, hot galvanizing is not paid attention, and this situation has occurred. In modern industrial production, this problem usually does not occur. Steel grating is a common type of steel grating used in various production fields. The middle distance of the bearing flat steel of the steel plate is 30mm, which conforms to the American standard. All steel grating series is prepared for strong resistance. The Flat noodles or edge of the steel grating: Compared with the edge plate * * 100, the required edge opening welded to the steel grating or steel grating is to prevent people or objects from falling, and the height of the flange can also be specified by the user. Compared with ordinary carbon steel, the overall cost of FRP grating is lower, but its one-time investment is higher than that of ordinary carbon steel. It has a long life and can be used for 20 years without protection. Therefore, its comprehensive economic benefit is far better than that of carbon steel. “Cold plating” also means that “electroplating” means that the zinc salt solution is electrolyzed and plated on the plated parts. Generally, heating is not required, and the amount of zinc is very small. The humid environment is very simple and can be ignored.
Hot-dip galvanizing is to galvanize the steel surface on the premise of hot-dip galvanizing. It has strong adhesion and is not easy to fall off. Although the corrosion of hot-dip galvanized pipe has also occurred, it can meet the technical and sanitary requirements for a long time.
