The steel grating carrying the flat steel and wrapping the flat steel has high strength on the front side, ignoring the lateral force, which may cause deformation or damage. Therefore, attention should be paid to the forward force of the steel grating, not the side. It is recommended to use nylon slings when loading and unloading. If the steel wire rope is used for hoisting, attention should be paid to maintaining the flat steel at the edge of the steel grating to avoid deformation of the outside of the steel grating and possible scraping of the galvanized layer. The long-term use of the steel grating due to the excessive load results in excessive bearing capacity, which in turn damages the structure and causes open welding at the joints. If this is the case, then the use time is a bit long, and the life may be shortened due to excessive load. However, if there are problems such as virtual welding and unqualified raw material thickness in production, then this is the reason of the manufacturer, including the planning and layout of the steel grating, the error of the steel grating device, etc. The public service of the steel grating, including the public service time of the flat steel diagonal, is controlled within a very good range. Whether the public service of flat steel meets national standards and national standards, flat steel is the most important part of the steel grating, and bears the largest load in the entire structure. In order to reduce production costs and earn more money, some manufacturers will use scrap steel for secondary processing of flat steel. After purchase, the alignment of the flat bar and the welding of the flat bar may not be completely parallel. Other flat steel may be slightly tortuous due to hoisting during transportation. Don't underestimate the twist. If the steel grating is slightly bent, it will cause welding failure. It may be that the welded steel grating is deformed, so proofreading is very important. Soldering is a very important part. The quality of welding will directly affect the bearing capacity and life of the steel grating. If the welding is not good, it may take several days to open the welding directly, and such steel gratings cannot be used. The hot-dip galvanizing treatment of steel grating is very important for steel grating. This is what the steel grating looks like. The first criterion for customers to judge the steel grating is the surface hot-dip galvanizing. Hot-dip galvanizing is not only beautiful, but also has anti-rust ability. The good quality of hot-dip galvanizing is the natural long life. The last point of packaging and delivery is the packaging and delivery of the steel grating. When loading, if the steel grating is thick or damaged, do not use a forklift to place it randomly. When loading the steel grating, you should also take it lightly, and the forklift cannot pick it up at will.
