The composite steel grating is a product composed of a steel grating with a certain cross-bearing capacity and a checkered plate with a sealing surface. After the composite steel grating is hot-dip galvanized, it will be warped and deformed due to heat, especially if the steel grating of a larger model is selected, it is difficult to level, please pay attention to the type selection.
For composite steel gratings, series 3 steel gratings are commonly used as the bottom plate, and series 1 or series 2 steel gratings can also be used; pattern steel gratings are commonly used for 3mm thick plates, and 4mm, 5mm, and 6mm plates can also be used.
The steel mesh is connected to the front or bottom of the composite steel grating to make a double mesh board, which can prevent small pieces from falling. The double mesh board is used in granaries, restaurants, and warehouses to prevent small animals such as mice from entering.
